氢氧化钙根管内封药预防根管治疗期间的急症

A prospective study of calcium hydroxide intracanal medicament against endodontic interappointment emergency

目的 探讨氢氧化钙 (calciumhycroxide ,CH)根管内封药对根管治疗期间急症 (Endodonticinterapp -ointmentemergencies,IAE)的预防效果。 方法 对使用不同药物根管内封药IAE的发生率进行比较。结果 CMCP、PC、IPI、CH组IAE发生率分别是为 2 2 .0 %、2 8.0 %、2 6 .0 %和 4 .0 % ,有非常明显的差异 ,疼痛指数亦以CH组最低。结论 CH根管内封药 。

Objective To investigate the effect of calcium hydroxide(CH) intracanal medicament against endodontic interappintment emergencies(IAE).Methods 200 patients with 200 teeth were undergoing root canal therapy(RCT) and then divided into 4 groups.CMCP group,FC group,IPI group and CH group,intracanal medicament were CMCP,FC,IPI and CH with the 4 groups.Results The respectives IAE frequencies of the 4 group were 22.0 %, 28.0 %, 26.0 %, 4.0 % which were statistical significant(P< 0.01 );And pain index of the 4 groups were statistical significance too(P< 0.01 ).Conclusion CH can prevent IAE in RCT.
