摘要
Aim This study aimed to measure the thickness of radicular dentine and cementum in incisors, canines and premolars, and to develop geometric average models. Methodology The roots of 220 extracted human teeth were sectioned in three horizontal parallel planes and measured using an optical microscope, For each cut surface buccal, lingual, mesial, and distal thickness of the root wall was measured. Mean values of the thickness at each location of each cut surface were calculated. The observed differences in thickness by tooth type. location, and section were compared by ANOVA and Student's t-test. Results Maxillary central incisors and maxillary canines had the greatest widths, In all teeth with a single root. the wall thicknesses were greater oil the lingual side than the buccal side, Although differences between mesial and distal thicknesses were noted in all groups of teeth. they were not statistically significant. Conclusions Wall thickness varied greatly, The lingual surfaces of roots were larger, All roots had thin walls in the apical third.
