目的:比较两种诱导剂在年轻恒牙根尖诱导成形术中的临床效果。方法:将发生牙髓病变或根尖周炎症的年轻恒牙68颗随机分为氧化钙碘仿糊剂组和Vitapex糊剂组各34例,两组常规根管预备后,分别用氢氧化钙碘仿糊剂和Vitapex糊剂作诱导剂行根尖诱导成形术,定期复查2年。结果:氢氧化钙碘仿糊剂组和Vitapex糊剂组分别取得88.2%和94.1%的有效率,两组之间差异无统计学意义。结论:氢氧化钙碘仿糊剂和Vitapex糊剂均为有效的根尖诱导剂。

Objective:To study the clinical efficacy of two materials in apexification of young permanent teeth.Methods:A total of 68 young permanent teeth with pulpitis or apical peridontitis were divided into two groups randomly.After canal preparation was carried out,these teeth were assigned to iodoform-calcium hydroxide paste or Vitapex paste differently for apexification,and the clinical efficacy was observed 2 years later after apexification.Results:With effective rate as 88.2% in iodoform-calcium hydroxide paste group and 94.1% in Vitapex paste group,there was no significant difference between two groups(P>0.05).Conclusions:Iodoform-calcium hydroxide paste and Vitapex paste are effective materials in apexification of young permanent teeth.
