摘　　要：本文设计了改良的冠室指数公式。用求积仪对91例上颌第一磨牙磨片的釉质、冠部牙本质和髓室的面积进行了测量,经统计学处理求得冠室指数与年龄关系的回归方程式:Y=72.32-0.442x(Y为推断年龄,x为冠室指数)。The materials investigated were 91 maxillary first permanent molars of Southern Chinese. The method of area measurement of structures of the teeth on longitudinal section is applied. The crown-chamber index was calculated according to the following formula: Crown-chamber index = [(area of enamel + area of pulp chamber)/(area of dentine of crown)] X 100 The regression formula to estimate age is: Y=72;32-0:442 X (X=crown-chamber index)
