    【Abstract】 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. ......
