摘　　要：目的　比较三金羟磷灰石根管封闭剂与传统根管封闭剂的封闭能力。方法　采用美兰渗漏染色法测定 3种根管封闭剂的根尖渗漏染色长度。结果　三金羟磷灰石糊剂、碘仿糊剂、氧化锌丁香油糊剂的根尖渗漏平均染色长度分别为 2 .40mm、4.37mm、5 .80mm。三金羟磷灰石糊剂与碘仿糊剂及氧化锌丁香油糊剂的美兰渗入长度有显著差异 (P <0 .0 1)。碘仿糊剂与氧化锌丁香油糊剂的美兰渗入长度无显著差异。结论　三金羟磷灰石根管封闭剂与传统根管封闭剂比较 ,具有很好的根尖封闭效果。Objective To compare the apical sealing ability of Sankin hydroxyapatite root canal sealer with traditional root canal sealers. Methods Determination of the length of apical dye leakage by methylene leakage test. Results The length of apical dye leakge of Sankin hydroxyapatite root canal sealer was 2.40mm, that of iodoform paste and zinc oxide eugenol paste was 4.37mm and 5.80mm,respectively. There was no significant difference between iodoform paste and zinc oxide eugenol paste( P >0.05);whereas there was significant difference between Sankin hydroxyapatite root canal sealer and iodoform paste or zinc oxide eugenol paste( P <0.01). Conclusion Sankin hydroxyapatite root canal sealer has better apical sealing ability than traditional root canal sealers. [
