Abstract: The sample consisted of 262 Chinese male skulls of known age (17-71). It was collected from Jiangxi, Qinghai, Jilin, Hebei, Anhui, Guizhou, Yunnan, Guangxi, Shangdong provinces. Observations were made at M1 and M2. Based on the changes on M1 and M2, the tooth attritions were sapareted into ten levels (I-X), and then were scored. The regression equations were constructed with scored M1 and M2 to estimate age at death.
The method of age estimation has a sufficient value for practical purposes.

Key words: Tooth attrition; Age estimation; Human identification
