Abstract

Detecting and measuring tooth wear is becoming a growing concern in dentistry. This means that there is a need for more accurate and non-destructive advanced techniques to take measurements to help overcome the problem, ideally during, intraoral examinations. This study recreated tooth wear using simulant materials in two types of wear test run in a Universal Mechanical Tester (UMT) using spherical zirconia antagonists run against two layer specimens made from VITA ENAMIC® and Fibrafill® CUBE. One was a reciprocating sliding test; the other a unidirectional wear test where the spherical zirconia probe returned to the start point out of contact, so there was an initial impact and then the sliding motion (“one-way impact-slide” mode). Different approaches were used to measure the resulting wear: Alicona (Infinite Focus) device (wear scar profile and roughness); Optical Coherence Tomography (OCT) (wear scar profile) and ultrasound (US) (wear scar depth), the latter two being options for intraoral measurements. The results demonstrated good comparability, but OCT has the best potential.
