方法：從山西醫科大學法醫學院及口腔醫院收集的636磨牙（無齲壞、無根尖病變）分為max1 、 max2 、 man1 、 man2四組，根據牙齒的增齡變化特點，篩選了5個與牙齡變化密切相關的指標（牙齒的磨耗、接觸區面積、牙本質髓室指數、根尖牙骨質的厚度、根尖牙本質透明） ，提出了指標的分級標準和評分標準，對各組的牙齒測量后進行數據處理和統計分析。 -
Results : all the five indexes ( dental attrition, contact area, the index of dentine marrow cavity, the thickness of cementum of root, the diaphaneity of dentine of root ) revealed a highly interrelated relationship with age. regression height was significant when the multiple regression equation, which was formulated with these five indexes and age and used to judge the age was statistically analyzed
