Abstract
Tooth wear is an ineluctable process with aging. Generally, tooth wear is composed of abrasion, erosion and attrition. Keeping sound occlusion is important factor for better quality of life. Virtual dental models are very effective tool for the research of tooth wear measurement. Therefore, this study aimed to measure maxillary second molar wear quantitatively.
Virtual dental models were constructed from 90 dental models (30 teenage, 30 thirty, 30 fifty). BCPH (buccal cusps plane height) was measured using software. Mean and standard deviation were calculated and analysis of variance was done for comparison between test groups. There were statistical differences between teenage and other groups. And the wear rate was generally slower than maxillary first molar. It is presumed that the eruption order and tooth size factors are reflected to wear rate of maxillary second molar.
