摘    要:目的观察不同年龄段人的牙齿在受到龋损刺激后,修复性牙本质的生成情况。方法收集5组不同年龄组含有牙本质浅层龋的离体牙,每组各5颗牙齿。制作标本切片,HE染色,显微镜下观察。测量修复性牙本质厚度,作统计学检验。结果5组不同年龄牙齿的修复性牙本质平均厚度分别为:3.36、2.6、2.8、4.2、3.36,统计学检验无明显差异。结论受龋损刺激后,不同年龄牙齿的修复性牙本质生成情况无明显差异。

关 键 词:修复性牙本质  成牙本质细胞  年龄

Abstract:Purpose To determine the reparative dentin formation characteristic after caries in different ages.Methods Collected 25 extracted teeth with shallow dentin caries in 5 age groups, each group 5 teeth. The teeth were sliced and dyed with HE.Then the thickness of the reparative dentin was measured.Results The thickness of the reparative dentin in 5 groups was 3.36,2.6,2.8,4.2,3.36. There was no significant difference among the groups.Conclusions There was no significant relation between the reparative dentin formation after caries and age.
Keywords:reparative dentin odontoblast age
