摘要 目的比较镍铬合金和钴铬合金两种非贵金属烤瓷修复体(PFM)对犬牙龈组织超微结构的影响。方法将3只健康犬以镍铬合金和钴铬合金两种PFM进行犬牙修复术,光镜和透射电镜观察犬牙龈组织的超微结构,TUNEL法检测凋亡细胞。结果镍铬合金PFM修复后,犬牙龈组织在镜下见大量的炎性细胞浸润,局部血管出血,细胞凋亡指数为58.63%±9.42%。钴铬合金PFM修复犬牙后,牙龈组织在镜下见炎性细胞浸润及局部血管出血较少,细胞凋亡指数为35.80%±7.58%。两种修复体修复后的牙龈组织细胞凋亡指数相比,P<0.05。结论镍铬合金PFM修复犬牙对犬牙龈组织超微结构的影响大,而钴铬合金PFM修复犬牙对犬牙龈组织超微结构的影响相对较小。
