Dr. Barwacz joined the staff at the Craniofacial Clinical Research Program in 2008, where he provides the latest in dental care to research participants as well as private patients.
Dr. Barwacz is a faculty member of the Department of Family Dentistry as well as the Iowa Institute for Oral Health Research.
Dr. Barwacz provides dental care to research participants and private patients in the Craniofacial Clinical Research program.
Dr. Barwacz's areas of research include human clinical translational research in dental implant therapy; peri-implant crevicular fluid cytokine and bone-mediator expression; peri-implant mucosal esthetics; implant-abutment biomaterials and surface topography; minimally-invasive, microscope-based dentistry; dental ceramics; and translational human in-situ caries model research.
His current research topics include:
- Examining how pro-inflammatory and bone metabolism mediators affect short- and long-term peri-implant mucosa and bone outcomes and homeostasis;
- Examining the use of novel miRNA technology to downregulate pro-inflammatory cytokines to arrest periodontitis-induced bone loss;
- Investigating peri-implant mucosal dynamics and esthetics as a function of abutment biomaterials, morphology, and surface topography;
- Examining prosthetic and educational factors that impact peri-implant mucosal esthetics via application of the standardized Pink Esthetic Score (PES);
- Examining fixed prosthodontic educational outcomes as they relate to minimally invasive, microscope-based dentistry;
- Evaluation of novel dentifrice compounds via the use of an in-situ, additive manufacuring (3D printing) human caries research model; and
- Examining clinical outcomes of next generation adhesive dental cements for all-ceramic restorations.
