The International Team of Implantology Awards Dr. Shankar Rengasamy Venugopalan, Dr. Satheesh Elangovan, and Dr. Erliang Zeng Two-Year Grant Totaling $50,000

Dec 13, 2019

The International Team of Implantology (ITI) has awarded Dr. Shankar Rengasamy Venugopalan, Dr. Satheesh Elangovan, and Dr. Erliang Zeng $50,000 to study the epigenetic mechanisms leading to peri-implantitis. The principal investigator of this grant, Dr. Shankar Rengasamy Venugopalan, is an associate professor in the Department of Orthodontics. The co-investigators are Dr. Satheesh Elangovan, professor in the Department of Periodontics and Dr.Erliang Zeng, associate professor in the Division of Biostatistics and Computational Biology.

Peri-implantitis, like periodontitis, is characterized by loss of alveolar bone beyond physiological limits, which makes it an irreversible condition and a complex problem to tackle. Currently, no single clinical strategy is available that can be utilized to treat peri-implantitis in a predictable manner. The epigenetic modifications play a significant role in the development of human diseases, such as cancer, neurological disorders, and autoimmune diseases. However, its role in peri-implantitis is not well characterized. Dr. Rengasamy Venugopalan and his team, with the grant funding from ITI, will study the epigenetic mechanisms underlying peri-implant pathologies using advanced next-generation sequencing technology. Understanding the epigenetic mechanisms behind peri-implantitis may help to develop novel and predictable preventive or therapeutic approaches.

Dr. Chris Barwacz Receives McLeran Award at Dean’s Club Reception

Dec 06, 2019

The Dean’s Club reception was held on April 15, 2019. Dr. Chris Barwacz, associate professor in the Department of Family Dentistry and the Craniofacial Clinical Research Program, received the James H. and Hermine E. McLeran Award because of his excellence as an educator and his commitment to patient-centered care.

Read more about Dr. Barwacz below:

Known as an outstanding clinical teacher and lecturer who is a role model for both predoctoral and graduate students in the college, Dr. Chris Barwacz has been teaching at the college for the past ten years. As an undergraduate (and throughout dental school), Dr. Barwacz was a research assistant in the laboratory of Dr. Stefan Strack, professor of neuroscience and pharmacology and associate chair for research.

After completing his D.D.S. at Iowa, he completed a residency in Advanced Education in General Dentistry at the Baylor College of Dentistry in Dallas, Texas. He then returned to Iowa as a research fellow in oral implantology and clinical research for two years before becoming a visiting assistant professor, and later an assistant professor in the Department of Family Dentistry. In 2018, Dr. Barwacz was promoted to associate professor with tenure.

As an educator, Dr. Barwacz lectures in five predoctoral and five graduate courses. For first-year dental students, he teaches didactic courses in periodontal aesthetics, and for fourth-year dental students, he is instrumental in their training and clinical supervision as it pertains to the restorative component of dental implant therapy. At the graduate level, he created and teaches a new course aimed at meeting a specific accreditation standard on implant provisionalization for periodontics. He is also actively involved in mentoring student researchers, and in 2015, he was recognized by the Student Research Group as the Mentor of the Year.

Dr. Barwacz SpeakingDr. Barwacz (shown speaking on the right) receives the most joy and satisfaction in observing fourth-year dental students grow and develop over the course of their last year of study and training. Their clinical and patient experiences over the course of the fourth year help them transition from often hesitant students who are completing initial comprehensive exams to confident and competent practitioners fully capable of making professional judgments and treatment plans for their patients independently.

“It is remarkable to see their progress over the course of the year, and it is particularly telling when you see the progress in reverse—seeing how skilled our graduates are by late spring, and then just weeks later seeing the incoming class start that process anew for themselves,” Dr. Barwacz explained.

During this process, Dr. Barwacz’s chief pedagogical goal is not only to educate his students, but to begin the process of treating his students like future colleagues, and part of that means guiding them to recognize when they should push beyond their comfort levels, while also identifying their own limits.

“Mutual respect is crucial to the teacher-student relationship; it is important to respect your students as future colleagues, to have high expectations of them, and help them become continual self-directed learners in the profession,” said Dr. Barwacz.

This relationship between the teacher and student carries over into how patients are treated.

Dean David Johnsen Presenting the McLeran Award to Dr. Chris Barwacz“My highest aim is for our students to be interested in, empathetic toward, and to provide excellent outcomes for their patients as ethical and honest practitioners. To do that, I realize that I have to model that behavior directly with students and patients,” Dr. Barwacz added.

Dr. Barwacz is also active in the larger profession as an active member of the American Association for Dental Research (AADR), American Dental Association (ADA), and Iowa Dental Association (IDA). He is also a recognized fellow of the International College of Dentists (ICD) and the Academy of General Dentistry (AGD). Dr. Barwacz also serves on the Fellowship and Certificate Steering Committee for the Academy of Osseointegration (AO), of which he is an active member. Furthermore, this past summer, he was inducted into the National Dental Honor Society Omicron Kappa Upsilon. This is a very selective recognition, as our local chapter can only elect one full-time faculty member each year.

According to Dr. Gustavo Avila-Ortiz, professor and Department Executive Officer (DEO) of the Department of Periodontics, and Dr. David Holmes, professor and DEO of the Department of Family Dentistry, “Dr. Barwacz has proven his commitment to the mission of our College and his extraordinary skills as a teacher and as a health care provider. We cannot think of a more qualified individual than Dr. Barwacz to be the recipient of the 2019 James H. McLeran Faculty Award.”

Because of his excellence as an educator and commitment to patient-centered care, it is our great honor to award Dr. Christopher Barwacz the 2019 James H. and Hermine E. McLeran Faculty Award (shown with the award and Dean David Johnsen).

Dr. William Synan

Dr. William Synan Named as Outstanding Predoctoral Educator in Oral and Maxillofacial Surgery

Oct 18, 2019

new (1).jpgDr. William Synan, D.D.S., was recently recognized with the 2019 Daniel M. Laskin Award for Outstanding Predoctoral Educator in Oral and Maxillofacial Surgery at the American Association of Oral and Maxillofacial Surgeons (AAOMS) annual meeting in Boston, Massachusetts. Dr. Thomas Indresano, AAOMS president, presented the award to Dr. Synan. (shown on the right).

Honorees are recognized because they exemplify the ideals of an educator, are respected by both peers and students, work to improve the relationship between dental students and oral and maxillofacial surgery residency programs, and are actively involved in efforts to improve undergraduate education.

Dr. Synan with Oral surgery faculty.jpegAs an oral and maxillofacial surgeon himself, Dr. Synan is devoted to the well-being of his students, the program at Iowa, and his profession. In addition to his ongoing work in oral and maxillofacial surgery (OMS), Dr. Synan has served as the predoctoral director educating hundreds of dental students at the College of Dentistry for 25 years. Dr. Synan also directs the resident’s educational and clinical experiences while they rotate from the University of Iowa Hospitals and Clinics to the College of Dentistry.

Dr. Synan has developed a unique “block system” where students focus solely on oral surgery for eight weeks during dental students' third year of dental training.

During this block, Dr. Synan has assembled and directs a first-class team of oral surgeons who provide an intensive exposure to dentoalveolar surgery, single drug sedations and outstanding didactic lectures. He personally developed the “check clinic” where the students present each and every scheduled surgery for that day, discussing the medical history and surgical implications including sterile technique, surgical technique and potential complications. Many of the oral surgeons on the "block" team joined Dr. Synan when he was presented with the award, as seen in the photo to the left.

According to Dr. Kirk Fridrich, DEO of the Department of OMS, “It is truly incredible to see how far he is able to “bring them along surgically” during this eight-week block rotation.”

Dr. Synan’s efforts have certainly born fruit. Thirty-two of Dr. Synan’s predoctoral students have gone on to match and complete their oral surgery residency at the University of Iowa; another fifty-eight have gone on to match and complete oral surgery residency at other programs in the United States for a total of 90 oral surgeons.

Dr. Synan has also served as a research mentor to countless students, which has resulted in numerous national presentations, awards, and scholarly contributions to the literature. He also served on eight Master's thesis committees for UI graduate OMS residents.

Dr. Synan with son, Nick, and wife, AnnDr. Synan's efforts have long been recognized by the UI College of Dentistry. He was the recipient of the prestigious James H. and Hermine E. McLeran Faculty Award for outstanding teaching in 2007. UI dentals students have also honored Dr. Synan with the Instructor of the Year award and the Instructor of All Four Years award. He has received the University of Iowa College of Dentistry Collegiate Teaching Award. Furthermore, in September of 2018, Dr. Synan was honored by the Iowa Dental Alumni Association as the Dental Educator of the Year.

The College of Dentistry is proud that the wider profession is now recognizing Dr. Synan’s educational impact on OMS at the University of Iowa and the profession as a whole. The photo on the right shows Dr. Synan with his son, Nick, and his wife, Ann.

Houjun Cao

NIH Awards Dr. Huojun Cao a 2-year grant for over $300K

Oct 04, 2019

The National Institutes of Health awarded Dr. Huojun Cao, assistant professor in the Iowa Institute for Oral Health Research and the Department of Endodontics, a 2-year grant for his project, “Computational Method for Identification of Master Transcription Factors in Craniofacial Tissues.”

The long-term goal of Dr. Cao’s research is to identify master transcription factors that are responsible for craniofacial development. A master transcription factor is a gene that regulates other transcription factors and associated genes. Thus, a change in the master transcription factor can significantly alter the entire cell or tissue type, and it, therefore, shows great promise for regenerative medicine.

Nevertheless, it is cumbersome, costly, and difficult to identify master transcription factors using experimental methods. Dr. Cao’s team has developed the prediction tool MTFinder to provide a computational method for identifying these master transcription factors. MTFinder incorporates both transciptome and epigenome data within a Bayesian statistical model so that the tool can identify master transcription factors in an inexpensive, efficient, and comprehensive manner. In preliminary studies, the tool successfully ranked all known master transcription factors in mouse embryonic stem cells and liver hepatocytes. Dr. Cao is now expanding this work to systemically identify master transcription factors that control craniofacial development.

He has two aims in the project:

1. Evaluate and determine the optimal configuration of MTFinder in various cell/tissue-types.

2.  Identify MTFs for craniofacial tissues using MTFinder with FaceBase’s transcriptome and epigenome data.

The hope is that this line of work can properly identify master transcription factors for cell lineage reprogramming and thereby improve the prospect of regenerative medicine, disease modeling, and drug screenings among others.

Dr. Cao’s team includes Dr. Brad Amendt, Dr. Xian Jin Xie, and Dr. Shankar Rengasamy Venugopalan.

Steve Levy

NIDCR Awards Dr. Steve Levy Two-Year Grant Totaling Over $650K

Sep 27, 2019

The National Institute of Dental and Craniofacial Research (NIDCR) has funded a new contract with Dr. Steven Levy (Wright-Bush-Shreves Endowed Professor of Research, Department of Preventive and Community, College of Dentistry, and Professor, Department of Epidemiology, College of Public Health) and colleagues at the University of Iowa. The Iowa Fluoride Study (IFS) and Iowa Bone Development Study (IBDS) have been funded by NIDCR research grants since 1991 and 1998, respectively, and have studied a cohort of participants from birth to age 24+.

The new award is for the period of September 1, 2019 to August 31, 2021 for a total of $657,649. The focus will be on data management and sharing of the 28 years of data collected previously in the Iowa Fluoride Study and Iowa Bone Development Study. This includes detailed questionnaire data starting from birth on fluoride exposures, tooth brushing, dietary patterns, and other factors; physical activity questionnaires and assessments with motion sensors; dental examination results for dental fluorosis, dental caries, malocclusion and other dental conditions; bone densitometry assessments; genetics data; and other study information. All study information will have individual identifiers removed and then will be prepared for sharing with other researchers in the United States and around the world. Then these data will be placed into a special repository supported by the National Institutes of Health and interested researchers will apply to have access to the data.

Other faculty directly involved with the new award are Drs. John Warren and Teresa Marshall (Professors, Department of Preventive and Community Dentistry), Dr. Kathy Janz (Professor Emeritus, Departments of Health and Human Physiology and Epidemiology), and Dr. Punam Saha (Professor, Departments of Electrical and Computer Engineering and Radiology).

Karin Weber-Gasparoni and Michael Kanellis (Department or Pediatric Dentistry), Dr. Joseph Cavanaugh (Department of Biostatistics), Drs. James Torner, Trudy Burns, and Linda Snetselaar (Department of Epidemiology), and Dr. Julie Eichenberger-Gilmore (Iowa City Veteran Affairs Medical Center).

Xi Chen

Dr. Xi Chen Receives Two-Year $426K Grant From NIH​

Sep 20, 2019

The National Institute of Nursing Research awarded Dr. Xi Chen, associate professor in preventive and community dentistry, a two-year R21 grant totaling over $426K for his project “Functionally-tailored Oral Care Intervention for Community-dwelling Older Adults with Dementia and Their Caregivers.”

Dr. Chen’s research project focuses on the oral health of older adults who have dementia and yet live in the community, rather than in a nursing home. These persons tend to have poor oral hygiene and a high risk of dental decay and other oral diseases, and their oral health declines can significantly diminish their overall health and well-being.

Dr. Chen said, “As a result of cognitive impairment, persons with dementia gradually lose their ability to perform oral self-care. They have to rely on caregivers for mouth care. However, the help from family caregivers is often limited because caregivers often don’t know how to assist their loved one, especially those with resistant behaviors. As a result, oral health is often poor in persons with dementia living in community, which can not only cause pain, infection and other systemic issues, but also make the relationship tense between caregivers and care recipients. We therefore want to develop a program to help these patients and their family caregivers.”

Dr. Chen’s prior research has investigated how oral-health interventions can improve overall health of older adults with dementia. With the support of his NIH K23 Career Development Award, Dr. Chen developed  “The Dental Activities Test”, which enables dental professionals to objectively evaluates the deterioration of oral self-care resulting from cognitive impairment. Together with his colleagues, Dr. Chen also developed the “Mouth Care Without A Battle”, which has become a standard oral hygiene protocol for residents of nursing homes in many states.

Based on his previous work, Dr. Chen’s current project will create an individualized oral hygiene intervention for community-dwelling persons with dementia and their caregivers, in order to improve oral health in persons with dementia, reduce oral care burden in family caregivers, and improve care partner relationships. The project has two specific aims:

1. Develop a staged and modifiable dyadic oral care intervention to provide functionally-tailored oral care rehabilitation for community-dwelling persons with dementia and need-based skills training their family caregivers.

2. Evaluate the feasibility and efficacy of the intervention in home settings through a randomized, controlled trial with 40 pairs of persons with dementia and their primary caregivers, including immediate post-intervention and 3-month follow-up.

Dr. Chen’s research team includes Dr. Xian Jin Xie from College of Dentistry, Dr. Sato Ashida from College of Public Health and Dr. Kristine Williams from the University of Kansas Medical Center.

Emily Lanzel

The Sjögren’s Syndrome Foundation Awards Dr. Emily Lanzel $25K Grant

Sep 06, 2019

Sjögren's syndrome is an immune system disorder that typically presents with two symptoms—dry eyes and a dry mouth. Although anyone can develop the disorder, most people aren’t diagnosed until later in life and the diagnostic process relies primarily on signs found in various tests (e.g., blood, eye, biopsy) that are used to rule out other medical explanations of the symptoms. The diagnosis is even more complicated for children, since when children have the syndrome, they often don’t present with dry eyes and a dry mouth.

Dr. Emily Lanzel’s project ““Salivary biomarkers for diagnosis of childhood Sjögren syndrome” addresses this difficulty by identifying biomarkers of the disorder so that clinicians will have a much more reliable method for detecting Sjögren's syndrome in children. Although prior studies have observed biomarkers in the saliva of individuals with adult Sjögren's syndrome, Dr. Lanzel and her team will expand this work by finding the biomarkers present in the saliva of children with Sjögren’s syndrome. They expect that they will be able to develop a specific biomarker profile for children with Sjögren’s syndrome so that diagnosis can be done earlier and more precisely. An early diagnosis would give clinicians and researchers more time for testing early intervention strategies that could help identify effective therapies for the disorder. 

Dr. Lanzel’s research team includes Dr. Paula Gomez Hernandez (resident in Pediatric Dentistry), Dr. Scott Lieberman (College of Medicine), and Dr. Kim Brogden (director of the Iowa Institute for Oral Health Research)

Kyungsup Shin

Dr. Kyungsup Shin Receives $20K Grant from the American Association of Orthodontists Foundation

Aug 30, 2019

The American Association of Orthodontists Foundation (AAOF) awarded Dr. Kyungsup Shin (Orthodontics) a $20K grant for his project “Fracture Energy Assessment Using CBCT: a pilot study for predicting risk of Post-Traumatic Craniofacial deformities.” Dr. Shin’s Co-Investigators are Dr. Donald Anderson (College of Medicine), Dr. Veeratrishul Allareddy (OPRM), and Dr. Xian Jin Xie (Biostatistics and Computational Biology).

Temporomandibular disorders are when injury or inflammation of the temporomandibular joint (the joint at the back of the jaw) causes pain in the area. About 60–70% of the general population are afflicted with the disorder, and it is particularly challenging to effectively treat without early diagnosis and treatment.

Dr. Shin’s project is investigating whether cone beam computed tomography (CBCT) can be used to determine how likely it is for disorders to develop as a result of a traumatic event. Post-traumatic osteoarthritis is one of the most challenging degenerative joint disorders, and the degree of trauma plays an important role in the development of the disorder.

Thus, Dr. Shin is using CBCT to determine the degree of trauma—that is, the objective fracture energy, and how that energy is distributed over different anatomical regions of the mandible. The method has been used previously in determining the fracture energy in long-bone (i.e., leg) fractures, and Dr. Shin believes it may be useful for trauma to the jaw as well.

He has two primary aims in this pilot study:

1. Validate the objective fracture energy scores computed from CBCT data.

2. Determine the association between fracture energy and anatomical regions of the mandible.

The ultimate aim is to develop a diagnostic tool for identifying the risk of developing a temporomandibular disorder, which can substantially improve early diagnosis and treatment.

“This study was initiated with dental student summer research and I acknowledge the hard work of Ms. Isabella Jasek and Mr. Ryan Mooneyham. I also thank the Student Research Program, including Dr. Teresa Marshall, Dr. Justine Kolker and Dr. Satheesh Elangovan for their support. With my co-investigators, I will work for successful completion of this study so that this can be another preliminary work for further scientific investigation.”  

Dr. Shin and the Department of Orthodontics also received another subcontract grant from the University of Alabama at Birmingham to continue studying “Anterior Openbite Malocclusions in Adults: Recommendations, Treatment, and Stability.”

Cathy Skotowski

Cathy Skotowski Receives the 2019 Collegiate Teaching Award

Aug 23, 2019

At the All-College Conference on Monday, August 19, Cathy Skotowski was awarded the 2019 Collegiate Teaching Award. The award is given to a faculty member who exhibits an “outstanding contribution to dental students’, graduate students’ or residents’ intellectual and professional development.”

Ms. Skotowski has taught in the Department of Pediatric Dentistry since 1989, and been a fulltime faculty member since 2003. She teaches a variety of courses in pediatric and preventive dentistry, and on the use of fluoride.

“I absolutely LOVE the position I have as Associate Professor in the Department of Pediatric Dentistry!  It is very important to me to be able to interact and teach dental students,” Ms. Skotowski said.  “Often my role involves helping students take all of the preventive dentistry knowledge and skills they have acquired and apply it to children, adolescents and their parents,” she added.

Her teaching is so effective that her students have even named a particularly location on molars “the Skotowski spot.” This spot is easy to miss, but still needs to be cleaned. It really means a great deal to her when she sees the success of her students making a difference for their patients.

Ms. Skotowski’s educational impact also extend well beyond the classroom and our student clinics. She has been involved in the creation and authoring of an educational flip chart, offered both in English and in Spanish, that is used to educate parents of young children on good oral health habits. This is one way that Ms. Skotowski helps “dental students find ways to connect to their patients and to personalize their preventive messages.”

She is also the faculty mentor of the American Academy of Pediatric Dentistry Student Organization, and thus, she helps facilitate and organize numerous community and outreach events where children and families receive oral health education, dental screenings, and fluoride applications. This work is a passion of Ms. Skotowski.

“I am always amazed at the interest and enthusiasm dental students have in volunteering at community events, especially when most are on weekends and evenings,” Ms. Skotowski said.  “And I firmly believe, and have seen over the years, those dental students who participate in these events as students are more likely to be involved in their communities long after they leave the dental school,” she added.

Dr. Karin Weber-Gasparoni, professor and chair of the Department of Pediatric Dentistry, said of Ms. Skotowski, “I truly believe that Cathy’s significant contribution to the education of our students is so very unique because she is not only a role model when it comes to reaching out to those in the community who are in higher need, but she works very hard to provide students with opportunities to experience the delivery of educational and preventive dental care outside the walls of a dental office.”

Liu Hong

Dr. Liu Hong Awarded $45K Grant

Aug 23, 2019

Synthetic bone-graft substitutes are considered a promising alternative approach to current standard treatments for oral and craniofacial bone defects. MicroRNAs (miRs) are small, non-coding RNAs that have emerged as important transcriptional regulators in both physiologic and pathophysiological conditions. The findings from preliminary research demonstrate that great potential exists to develop novel therapeutics for bone regeneration of craniofacial and periodontal bone defects by targeting miRs, and miR-200a specifically.

The NaturemiRI, LLC R&D team has developed the Plasmid-based microRNA inhibitor system (PMIS), a non-toxic, nucleic acid-based method of microRNA inhibition. 

This particular research project is part of an overall series of projects intended to validate and commercialize a PMIS-infused collagen sponge for use in clinical dentistry. Specifically, Dr. Hong’s team expects to show that a PMIS construct inhibiting miR-200a (PMIS-miR-200a) promotes high-quality bone growth in the alveolar ridge of dental patients, thereby offering a new tool in the treatment of craniofacial defects and tooth extractions performed in anticipation of dental implantation.

The project has three primary aims:

  1. To optimize the in vitro transfection efficiency and osteo-inductive capacity of PMIS-miR-200a from collagen sponges.
  2. To determine in vivo osteoinductive capacity of PMIS-miR-200a adsorbed in collagen sponges.
  3. To determine the toxicity risk of PMIS-miR-200a in vitro and in vivo.
Aline Petrin

NIH Awards Dr. Aline Petrin Grant Totaling Almost $700K

Aug 16, 2019

Dr. Aline Petrin (Iowa Institute for Oral Health Research) has been awarded a 5-year career-development NIH K01 grant totaling almost $700,000 for her project, “A Twin Approach for Genome-Wide Differential DNA Methylation in Orofacial Clefting.” Dr. Petrin developed the proposal as a post-doctoral researcher with support from the college’s R90/T90 training grant.

Dr. Petrin’s project draws on a powerful approach to the study of epigenetics and disease using discordant monozygotic twins to detect key epigenetics factors that play a causal role in orofacial clefts. The twin approach allows researchers to control for confounding factors, including genetic background, environmental exposure, age, gender, and other such effects, and thereby uncover epigenetic risk factors that are invisible to conventional genome-wide association studies and sequencing methods. Dr. Petrin and her mentors have successfully applied this twin approach to oral facial clefts (OFCs), and they have discovered the first causal gene for Van der Woude syndrome, the most common syndromic form of OFCs.

Dr. Petrin’s project expands on this work. She hypothesizes that aberrant DNA methylation plays an important role in the etiology of OFCs and she, with the support of her mentors, gathered the largest (to date) set of monozygotic twins in which one has a nonsyndromic OFC and the other does not to characterize genome-wide differentially methylated regions that can impact the risk for orofacial clefts. Her two primary research aims are to:

  • determine genome-wide methylation patterns in DNA samples from monozygotic twins discordant for OFCs.
  • explore the genetic-epigenetic interactions involved in the etiology of OFCs.

Dr. Petrin expressed her gratitude for the grant and the support she has received from the college: “I am truly honored to receive this award and thankful for the support I have received from the Department of Orthodontics, the Iowa Institute for Oral Health Research, and the College of Dentistry. This award is a wonderful opportunity to leverage my knowledge of craniofacial genetics into the proposed epigenetic studies. I feel incredibly lucky for having a team of outstanding researchers and clinicians involved in the project and I will take this opportunity to further develop my line of research and skills as a mentor and educator.”

The second, titled "Pediatric Dental Resident Outreach Project," in the amount of $3,500 is for pediatric dental outreach efforts in Forest City and Waukon. The funds will be used to help offset the expense of new equipment, a Nomad, that will be used for these outreach events. The equipment will allow pediatric residents to provide care in a more efficient manner to individuals in those communities. The remainder of the cost of the equipment is coming from the Pediatric Dentistry Excellence Fund. 

Shaoping Zhang

Dr. Shaoping Zhang Receives NIH Grant

Jul 26, 2019

Dr. Shaoping Zhang (Periodontics) was awarded a three-year National Institutes of Health grant totaling almost $750,000. The project is part of Dr. Zhang’s ongoing work to better understand host-pathogen interactions at the mucosal surface, and this type of grant is intended to help independent investigators develop as a researcher. The hope is that this research will lead to the development of novel preventive, diagnostic, and therapeutic means to improve oral health and address periodontal disease.

Dr. Zhang’s aims for the project are to:

1. Determine the role of the IL-17/TRAF3IP2 pathway-modulated local gingival immune response with a focus on IL-22 activity.

2. Investigate the role of the IL-17/TRAF3IP2 pathway in mucosal physical barrier function and mechanism of IL-17-regulated tight junction structure.

3. Determine the TRAF3IP2 variant effect on immune response as reflected by the transcriptional and post-transcriptional regulation of chemokine synthesis and barrier function in genomically engineered, human gingival epithelial cells.

Kyungsup Shin

Two Orthodontics Faculty Receive Prestigious Faculty Fellowship Awards from the AAO

May 03, 2019

Shankar Rengasamy Venugopalan.jpgThe American Association of Orthodontists (AAO) awarded three prestigious $60,000 Faculty Fellowship Awards, and Dr. Kyungsup Shin and Dr. Shankar Rengasamy Venugopalan were honored to receive two of them after a national level review, based on their commitment to dental education and academics.

Given that there were only three awards given across North American, Dr. Tom Southard said that it was “amazing for two of Iowa’s faculty to receive them.”

These fellowships were instituted by the AAO in response to a 2015-2016 American Dental Education Association report that a large number of dental and dental specialty faculty are close to retirement. Thus, in 2018, the AAO 2018 House of Delegates reinstated the Faculty Fellowship Awards Program. Each award provides funding in an amount of $60,000 for two years.

Regarding the award, Dr. Shin said, “I am truly honored by this fellowship and attribute this to the support from our Department and the College of Dentistry. I will leverage this opportunity to become a dedicated educator and an excellent mentor in our specialty.”

Dr. Rengasamy Venugopalan added, “I am truly humbled to receive this fellowship award from the AAO. The biggest road block for pursuing an academic career in dentistry is the student loan burden. The AAO has done a commendable job in alleviating this burden by providing these fellowship awards. I am delighted and thrilled that two of these awards was given to our faculty. This award has given me a renewed hope to pursue bigger dreams in orthodontic education, research, and service.”

Many other specialty organizations have similar fellowship opportunities like this, and Dr. Shin and Dr. Rengasamy Venugopalan’s experiences show that many of our college’s faculty members would be competitive for those awards. Please reach out to Dr. Shin and Dr. Rengasamy Venugopalan if you are interested in applying for such an award within your specialty area.

Please join me in congratulating Dr. Michelle McQuistan.

Gustavo Avila-Ortiz

Maximizing Bone Preservation

Mar 08, 2019

For each month spent on the International Space Station, an astronaut will lose approximately one to two percent of bone mass. Since the skeleton is not being used to support the full weight of the body, the bones weaken and lose mass and density. When a bone is not being properly stimulated, it usually undergoes disuse atrophy and subsequently shrinks. When a tooth is removed from its socket, this resorptive phenomenon also occurs with the alveolar bone—the bone that provides direct support to the teeth.

Just as scientists have found ways for astronauts to maintain and strengthen bones while living in space, Dr. Gustavo Avila-Ortiz is exploring new therapies to preserve the alveolar bone.

It is common to lose a significant amount of alveolar ridge volume in the first three to six months after a tooth extraction. “Without a tooth there to stimulate the bone, the alveolar ridge volume will decrease,” Avila-Ortiz explained. “Bone loss can lead to an intense remodeling of the contour of the alveolar ridge, which may make it difficult to replace a missing tooth with a dental implant,” he added.

In the late 1990s and early 2000s, clinicians began to explore various ways to preserve the alveolar bone. “Over the years different bone substitutes, like bovine-derived xenograft or a human-derived allograft, typically applied in a particulate form, have been used to fill the tooth socket after tooth extraction in an attempt to reduce alveolar bone resorption. It has also been shown that sealing the socket orifice with a barrier material, such as a biocompatible membrane, is important to protect the underlying bone during the healing process.  This approach, known as alveolar ridge preservation, is a widely used therapy in contemporary practice. But it is not the only available option” Avila-Ortiz commented.

Another alveolar ridge preservation treatment involves intentionally leaving part of the tooth in the socket to stimulate the bone. “Although it can work, this treatment is technically hard, it isn’t always possible, and it may increase the risk of infections and failure of implant integration,” Avila-Ortiz said.

Although he admits that there is no single fix-it-all solution, Avila-Ortiz has been researching how different biomaterials can preserve the natural architecture of the bone after an extraction, minimize the detrimental effects of tooth loss, shorten the healing time between extraction and placing an implant, and reduce the need for additional bone grafting to allow for implant placement.

Recently, Avila-Ortiz has been working with Dr. Liu Hong and Dr. Brad Amendt, using the extraction socket as a research model, on therapies that would apply microRNA therapy for oral bone regeneration purposes. “It’s really very promising, and we are almost ready to initiate the first clinical trials with humans,” Avila-Ortiz said.

One of the main goals of Avila-Ortiz’s research in this area is to discover both new therapies and the influence that patient-specific factors (i.e., local and systemic) have on the outcomes of treatment.  “One size does not fit all. One of our objectives is to deliver individualized care to each of our patients,” Avila-Ortiz explained.


The College of Dentistry Goes to Washington

Mar 01, 2019

IMG_1457.jpgTwo different groups of representatives from the College of Dentistry visited Washington, D.C. on February 26 to advocate on behalf of important oral-health-related legislative priorities.

Dean Johnsen, Dean Amendt, Dr. Teresa Marshall, and fourth-year dental student Leah Barshinger visited with the offices of Iowa Congressman Dave Loebsack and Iowa Senators Chuck Grassley and Joni Ernst to advocate on behalf of continued and increased research funding for the National Institutes of Health and the National Institute of Dental and Craniofacial Research. They were there as representatives of the AADR and the National Student Dental Research Group. The image to the right shows Leah Barshinger, Dean Amendt, Chris Fox (CEO of the AADR), and Dr. Teresa Marshall. 

Dean Johnsen said that it was also an excellent opportunity to communicate the “value the College of Dentistry brings to Iowa.”

Representative Loebsack also addressed 100 delegates from around the country. He spoke on the importance of oral health as a crucial part of overall health and the value of advocating on behalf of oral-health fields.

2019 AAPD Advocacy Day.JPGThe Department of Pediatric Dentistry also sent representatives to Washington, D.C. on February 26 as part of the annual Pediatric Oral Health Advocacy Conference organized by the American Academy of Pediatric Dentistry. This is particularly fitting given that February is Pediatric Dentistry month.

Dr. Matt Geneser (Pediatric Dentistry) and second-year pediatric dentistry residents Dr. Liz Wilkinson, Nate Green, Kirstina Gratz, and Casey Goetz met with the offices of Senators Chuck Grassley and Joni Ernst and with Representatives Dave Loesback and Abby Finkenauer to advocate on behalf of continued support for Title VII funding for pediatric dentistry training programs and dental faculty loan repayment plans.

Rena D'Souza

The College of Dentistry’s Annual Local AADR Research Day Was a Great Success

Feb 15, 2019

With over 100 presentations from students, staff, and faculty and an excellent keynote address by Dr. Rena D’Souza, the College of Dentistry’s Annual Local AADR Research Day was a great success. 

Our keynote speaker, Dr. D’Souza, is Professor of Neurobiology, Pathology, and Medicine and the Associate Vice President of Research at the University of Utah School of Medicine. As an outstanding scholar, leader, and mentor in our profession, she has held and continues to hold many prominent positions at her university and in the wider profession, including serving as President of the International Association for Dental Research, the 41st President of the American Association for Dental Research, and many other prominent positions related to oral health. 

According to Dr. Brad Amendt, this is the first time that the current IADR president has addressed the college for our Research Day.

Dr. D’Souza expressed admiration for the college's efforts to develop an integrated research program that includes basic science, translational, and clinical research. She said that the college has become a cutting-edge institution in this respect, and in her opinion, it is why “Iowa is one of the top 10, if not top 5 dental colleges in the United States.”

Dr. D’Souza’s keynote address covered a variety of topics including important areas for research in dentistry and the oral sciences, her goals for the IADR, and the specific kinds of genetic research that she has explored personally.

College of Dentistry researchers are playing important roles in some of the important areas for research that Dr. D’Souza highlighted, including big data analysis, precision and personalized medicine, genomic research, microbiome research particularly regarding prebiotics or probiotics for the oral microbiome, and translational and clinical research.

And Dr. D’Souza’s own research shows the great value of collaborating with colleagues in a variety of related fields—from clinicians working with basic science researchers to oral science researchers learning from hair follicle research.

After her keynote address, Dr. D’Souza spent a great deal of time talking with faculty, staff, and students.

It was a wonderful opportunity for the college to deepen our relationship with Dr. D’Souza.

Feb 08, 2019

The New York Institute of Technology (NYIT) granted Dr. Erliang Zeng a subaward grant for a project funded by the National Cancer Institute, a part of the NIH. The project, Molecular Circuit of Multi-ciliogenesis Regulates Choroid Plexus Differentiation and Tumor Development, investigates how the molecular circuit of malignant choroid plexus tumors in children interact with signaling pathways as the tumors are formed. Dr. Zeng will be responsible for leading efforts in bioinformatics development and data analysis for the project. Dr. Zeng brings significant expertise to provide outstanding support for the project on the omics data integration and bioinformatics analysis. This project will foster the already existing relationship and collaboration between subaward PI Erliang Zeng at UI and PI Haotian Zhao at NYIT and will strengthen the bioinformatics program development in the Division of Biostatistics and Computational Biology of the UI College of Dentistry.

Teixeira, Erica

Dr. Erica Teixeria Continues Industry-University Collaboration with New Grant

Feb 01, 2019

Tokuyama Dental Corporation awarded Dr. Erica Teixeria a $134,000 grant for the project, “Esthetic outcomes of a newly developed dental composite and adhesive system: a randomized clinical trial.”

Dr. Teixeria’s project continues a long-term partnership between the College of Dentistry and Tokuyama. More specifically, Dr. Teixeria and her research team will conduct a 36-month randomized controlled clinical trial to evaluate and compare the esthetic outcomes and patient satisfaction of a simplified newly developed dental composite system for the esthetic region to a nanohybrid composite system. Although dental composite systems have been used extensively for the anterior region, it can still be difficult for clinicians to select the proper shade and the materials may not last as long as clinicians would like. This new system has been developed to improve the esthetic outcomes and patient satisfaction by enhancing its blending capability.

Dr. Teixeria research team includes: Drs. Amira Ahmed, Steve Armstrong, Hanan Elgendy, Sandra Guzman-Armstrong, Aditi Jain, Justine Kolker, Rodrigo Maia, Patricia Meredith, Cristina Vidal, Marcos Vargas, Xian Jin Xie, and research coordinator Karen Kluesner. 

Jin Xie

A World-Class Program for Biostatistics and Computational Biology

Jan 25, 2019

XieTeam_082018_400wide.jpgFrom baseball to politics, big data has taken the world by storm. It has revolutionized our recreational pursuits and our health care decisions. Oral health research is no exception to this trend, and the College of Dentistry is on the cutting edge of that trend.

The Division of Biostatistics and Computational Biology provides statistical and computational expertise for the college’s research projects. Although in past generations statistical analysis was mostly performed by an individual researcher, it is now an expectation that elite biomedical research centers have a designated biostatistics division.

“A single person is simply not adequate anymore. The databases are too large and of great complexity, and any person would have to know database management, frequentist methods, Bayesian methods, bioinformatics, structural equation modeling, etc.,” said Dr. Xian Jin Xie, director of the Division of Biostatistics and Computational Biology.

Xie joined the college a little over a year ago in fall 2017, and since then, his division has worked with over 40 researchers at the college. Xie has really appreciated the collegial working environment. “Everyone is so easy to work with and the faculty really support one another,” said Xie. “This environment really lays the foundation for achieving more NIH grants, and potentially large multi-investigator program grants,” Xie added. 

Xie also underscored how much support he’s received from the college administration. “We have received great support from Dean Johnsen, Dean Schneider, and Dean Amendt. Everything we’ve asked for, they’ve given us.”

And Xie has asked for a lot! Ultimately, he aims for the division to become a model for dental colleges across the country. “We are the first college in the country to have a division of biostatistics and computational biology,” Xie said. This new methodological focus is poised to become the new standard. 

Xie’s first year plan had three goals for accomplishing that ambitious goal.

First, he sought to recruit high quality faculty and research staff, like associate professor Dr. Erliang Zeng, a new faculty member in the division who specializes in bioinformatics. Adding Zeng was crucial for establishing the division’s expertise in computational biology.

Second, he wanted to continuing building on the college’s grant writing success, and his division has helped with 10 NIH grant submissions and many foundation sponsored grants this past year.

Third, he plans to develop educational modules and one-hour lectures to help improve knowledge of statistical methods with the aim of helping all of our researchers, but especially our clinical researchers who want to do research but have limited time because of their extensive clinical responsibilities

Although a great deal of Xie’s attention is dedicated to serving as the director of the division and advising on dental research projects, he also conducts and publishes his own statistical research on 1), statistical model diagnosis; 2), high throughput data analysis; and 3), new design of Phase I Clinical trials.

“In my position, you need a breadth of knowledge to support various basic science and clinical research projects, but it’s always fulfilling and enjoyable to have your own research too,” said Xie.

The Division of Biostatistics and Computational Biology is located on the first floor of the north wing of the Dental Science Building and is available for consults for upcoming research projects.

Cristina Vidal

From the Bench to the Chair: Translational and Clinical Research at the College of Dentistry

Jan 11, 2019

Dental researchers at the college have a strong history of pursuing basic, clinical, and translational research in a collaborative and supportive environment with the goal of improving patient care. “The ultimate goal of our research is to benefit and contribute to our community and society,” said Dr. Cristina Vidal, assistant professor in operative dentistry. 

The college’s translational and clinical research has flourished by drawing knowledge and experience from College of Dentistry colleagues and other disciplines—from medicine to physics, from public health to engineering.

“Many questions in dentistry can be addressed, at least in part, with advances that have been made in other fields such as medicine or engineering. So I often start by asking ‘What approaches are being used in other fields?’” said Dr. Kyungsup Shin, assistant professor in orthodontics and director of clinical research for the college.

Trishul_DSBW.jpgFor example, in the field of Oral and Maxillofacial Radiology, clinical professor Dr. Trishul Allareddy has been using his expertise to improve the quality of dental radiographic images as the co-chair of the Standards Committee on Dental Informatics for the American Dental Association and Co-Chair of DICOM international standard for Dentistry.

“Most of the 180,000 US dentists make radiographs in their offices, but they have minimal training in radiology in dentistry and often the scope of that training does not address quality assurance across all modalities of imaging in dentistry,” said Allareddy, “and that’s why it is so important to know how things should be done.”

Having high-quality images requires a goldilocks level of radiation—just enough to get sufficient information for clinical judgments, but not too much, which exposes the patient to too much radiation.

“Unfortunately, many of the digital intraoral radiographs that dentists take are not clinically useful as the patients are underexposed and the radiographs do not have enough information,” Allareddy explained.

In addition to creating standards for the use of x-rays in dental clinics, Allareddy is also researching best practices for the use of cone-beam computed tomography (CBCT) in dentistry. CBCT technology is used when regular dental radiographs are not sufficient—for example, in cases of oral cancer or for dental implants.

“Dentists need to be aware of what imaging tools are useful in which contexts; it’s really about optimizing our care for each patient,” Allareddy said.

Vidal_Portrait_111418b_small.jpgThat’s also a central part of Vidal’s research. Whether designing materials that will take less time to use or discovering bioactive materials and mechanisms that can stimulate and regenerate teeth, Vidal’s research is focused on patient well-being.

Two of Vidal’s recent projects illustrate this line of research. In one, she is investigating a novel universal bonding agent that doesn’t require any light curing—and thus, it could reduce the time a patient spends in the dentist’s chair. Her research team will determine how well this new agent performs and make recommendations for its use in clinics.

In another, her team is exploring how a certain plant-derived compound that can preserve, repair, and restore the bond between dentin and resin material.

Although these particular clinical applications are important, Vidal is also interested in the underlying mechanisms. “By understanding both the enzymes that degrade collagen, and the natural processes that inhibit degradation of the resin-dentin bond, we will have a greater understanding of the most efficient and least invasive approaches in the clinic,” Vidal said.

Kyungsup_DSBW.jpgLike Allareddy and Vidal, Shin’s research—specializing on the temporomandibular joints (TMJ)—exemplifies the college’s patient-oriented and collaborative research.

After asking about approaches in related fields, Shin found out that an orthopedic research group (Dr. Don Anderson) had used medical CT images of leg fractures to determine the risk for developing arthritis as a result of the fracture. Shin wanted to apply that research to his specialty, the TMJ.

Drawing on Allareddy’s expertise in radiology and CBCT images, Shin hopes to develop a predictive diagnostic tool using CBCT images to assess the risk of developing osteoarthisis in the TMJs after trauma to the joint. Post-traumatic osteoarthritis in this joint is particularly challenging to treat, often requiring extensive surgical procedures.

“Without reliable predictive diagnostic tools, we don’t really know when to intervene to prevent long-term complications associated with post- traumatic osteoarthritis,” Shin explained.

Shin has also been collaborating with colleagues in other colleges—Dr. Aliasger Salem in pharmacy and Dr. James Martin in medicine—on basic science research concerning bone and cartilage tissue regeneration in the TMJ.

Allareddy, Vidal, and Shin are wonderful pictures of the collaborative, translational, and clinical research being conducted at the College of Dentistry. Whether patients are having a dental radiograph made, having a broken tooth repaired, or having surgery on their temporomandibular joint, these researchers are finding a way to make a difference.

Anamali, Sindhura

ADEA Awards Dr. Anamali $8,500 Grant for Teaching General Dentists about Advanced Imaging in Radiology

Jan 11, 2019

ADEA awarded Dr. Sindhura Anamali (Oral Pathology, Radiology, and Medicine) a $8,500 grant. The project for the grant is titled “Developing Learning Modules in Intra-oral, Extra-oral and Advanced Imagining in Radiology for Better Understanding and a Reference of Anatomy for General Dentists.”

The aim of project is educate general dentists about the vast quantities and complexity of information contained in cone-beam computed tomography (CBCT) scans. Dr. Anamali’ s modules will include a comprehensive details about the complexity of anatomical information available on a CBCT scan.  The hope is that the module will assist dentists deliver quality patient care.
