Research Summary/Interests

Pathogenesis of abfractions: determine whether occlusal stress, toothbrush abrasion, or both are etiological factors for the development of non-carious cervical lesions (abfractions).

Toothbrush biomechanics: use strain gage technology to clinically measure the pressing force, stroke frequency and dynamic stiffness involved in toothbrushing.

Correlate clinical and in vitro data through the transfer of new state-of-the-art technology into the clinical setting.

Test the Virtual Dental Patient software developed by Dr. Ralph DeLong through his NIH/NIDCR grant. The VDP software is a computerized simulation of a dental patient that creates accurate 3D renditions of the jaws and teeth.

"A Digital Environment for Teaching Oral Anatomy - a Student Oriented Approach" - a teaching aid for Oral Anatomy students. It allows the students to manipulate computerized 3-D models of individual, anatomically correct teeth.
