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)。

关键词: 结构面积测量;冠室指数;回归方程;华南人

Abstract: The materials investigated were 91 maxilhary 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 erown) ]×100
The regression formula to estimate age is:
Y=72. 32-0: 442X.
(X=crown-chamber index)

Key words: Area measurement of structures; Crown-chamber index; Regression; Southern Chinese
