Abstract:

摘要 目的:研究不同浓度磷酸酸蚀对氟斑牙釉质微拉伸粘接强度的影响。方法:实验分为4组,对照组30颗正常牙,实验组90颗氟斑牙按照TFI评分分为3组:轻度氟斑牙组、中度氟斑牙组和重度氟斑牙组。每组牙再分为3个亚组,分别采用35%、40%和45%磷酸酸蚀。进行微拉伸粘接强度测试,扫描电镜观察牙釉质粘接界面,光学显微镜观察断裂模式。结果:氟斑牙粘接强度相比对照组降低(P<0.05),氟斑牙在不同浓度磷酸酸蚀下粘接强度有显性差异(P<0.05),40%酸浓度时粘接强度最大,对照组在45%酸浓度下粘接强度最小。结论:氟斑牙的粘接强度低于正常牙;对于氟斑牙采取不同浓度酸蚀剂会改变其全酸蚀粘接强度,但酸浓度过高反而会导致粘接强度下降
