Clinically Relevant 3d Characterization Of Simulated Non-Carious Cervical Dental Lesions And The Effects Of Toothbrush And Toothpaste Types On Wear, James Needy
Biomedical Engineering Undergraduate Honors Theses
This study sought to develop a novel method to quantitatively characterize non-carious cervical lesions (NCCLs) using an intraoral scanner (IOS) paired with Geomagic Wrap mesh software. The goal was to compare results with those obtained using an optical profilometer and Proscan superimposition software for clinical application. Comparisons were made using a previously published dataset aimed at measuring tooth loss associated with differing toothbrush and toothpaste types. Results show good comparability between methods and confirm that variation in brush stiffness and paste abrasivity result in significantly and predictably different levels of NCCL development. Extracted human maxillary premolars were assigned to one …
