Tooth enamel is the hardest substance in the body, but it is still subject to wear due to the harsh oral environment. Tooth wear can be categorized into mechanical and chemical types and can threaten an individual's eating rate and habits. Researchers have proposed using Optical Coherence Tomography (OCT) to measure tooth wear in dentistry, but they rely on the aid of depth-measuring apps. In this work, I systematically reviewed the global prevalence of tooth wear and statistically estimated the number of people affected by teeth wear. I also explored the possibility of using OCT in the quantification of tooth wear without the help of any length/depth measuring apps. I emulated wear in a restorative material, compared the results with the standard method (Surface Profiler), and used OCT to compare emulated wear in three different restorative materials. The results showed that OCT is a step closer to being fully adopted as a clinical imaging tool in dentistry.
