Dr. Rodrigo Rocha Maia has received two grants from the American Dental Education Association (ADEA)
A $4,100 ADEA grant will support his research project, "Comparison of Light Propagation in Dental Tissue and Resin-Based Composite by Lasers." The use of laser (He-Ne) in three different wavelengths (red, green and blue) will be used to evaluated the light propagation (absorption, transmittance, attenuation coefficient, scattering and back scattering) in enamel dentin and dentino-enamel junction (DEJ) and to compare the difference among three incremental build-up techniques using a nano-filled resin based composite. Dr. Maia is principal investigator. Dr. Hanan Adel Elgendy, an operative dentistry resident, is co-investigator.
A $3,300 ADEA grant will support Dr. Maia's research on "Esthetic Blending: Visual vs. Spectrophotometer Data Analysis for Different Bevels in Class 4 RBC's Direct Restorations.". The goal of this research will be to determine what type of bevel to use on class IV build ups. Dr. Maia is principal investigator. Dr. Tracy D'Antonio, an operative dentistry resident, is co-investigator.
