氢氧化钙预防根管治疗期间急症的临床疗效观察

Clinical study of calcium hydroxide in prevention of endodontic interappointment emergencies

目的:探讨氢氧化钙(CH)根管内封药用于预防根管治疗期间急症(IAE)的临床疗效。方法:选择慢性根尖周炎患者129例,随机分为实验组(75例)和对照组(54例)。实验组用CH做根管内封药,对照组用甲醛甲酚(FC)做根管内封药。1周后,对IAE的发生率进行比较。结果:CH根管内封药组的IAE发生率明显低于对照组,两组疗效差异有显著性(P<0.05)。结论:CH根管内封药能有效预防根管治疗期间发生的急症。

Objective：To investigate the effect of calcium hydroxide intracanal medicament in prevention of endodontic interap-pointment emergencies （IAE）. Methods： 129 patients with chronic periapical periodontitis were divided into observation group （75 eases） and control group（54 eases） randomly. In the observation group calcium hydroxide was placed in the instrumented root canals;formoeresol was used for intracanal medicament in control group. The clinical effect was observed in 1 week after intracanal medication. Results：The IAE frequeney of observation group was lower than that of control group, and the difference was significant（P〈0.05）. Conclusion：Calcium hydroxide is effective in preventing the occurrence of IAE.
