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

目的:觀察激光在根管內照射后對根尖周組織的作用.方法:選3隻小型豬，全麻下將乳前磨牙開髓、抽髓，根管擴大后，激光照射30秒，做常規根管充填.對照組為常規根管充填. 1天、 3天、 7天和15天後觀察根尖周組織的變化.結果:激光照射后1天，根周膜血管充血、輕度炎癥，對照組只有根尖周膜充血.激光組組織反應比對照組稍重.激光照射后3天和7天，少數病例根周組織有輕度的刺激與對照組的病理表現相近.激光照射后15天部分標本根周膜正常，部分標本有輕度炎癥反應，與對照組結果基本相似.結論:本激光照射條件對根尖周組織沒有明顯損傷作用，可供臨床應用時參考Dental root - canal instruments - files, reamers, barbed broaches, rasps, paste carriers, explorers and cotton broaches
