摘　　要：目的:通过调查普通人群牙齿切缘及咬面的磨耗情况,研究牙齿磨耗与年龄和性别的关系.方法:分年龄段对抽样人群进行牙齿随机检查,采用Smith和Knight牙齿磨耗指数TWI分度方法,对416例受检人群的11395颗牙齿的切缘和咬面进行磨耗度检查.对各个牙齿的磨耗数据进行统计学分析.结果:测得当代普通人群牙齿平均磨耗度为1.51.不同年龄段牙齿的磨耗程度有显著性差异(P<0.05),牙齿的磨耗程度随年龄增加而逐渐加重.同名牙齿的平均磨耗程度在男女性别中无显著性差异(P>0.05).结论:牙齿磨耗呈现增龄性变化,但不存在性别差异.AIM： To study the correlation between tooth wear and age as well as gender by investigating the state of average tooth wear on incisal and occlusion surfaces in general population. METHODS： A sample group of 416 adults aged from 15 to 75 years old was randomly enrolled in this study. The Smith and Knight tooth wear index（TWI） was applied to assess the degree of the incisal and occlusion surface wear of total 11 395 teeth from the group. All the data were analyzed statistically. RESULTS： The average attrition gradation of the teeth in general population was 1.51. There was great significant variation on degree of tooth wear among different age groups （P 〈 0.05）, while no significant difference in the tooth wear between male and female （P 〉 0.05）. CONCLUSION： Tooth wear is synchronous with the increase of age, while there is no apparent difference between male and female.
