碧兰根充糊剂一次性根充窦道型慢性根尖周炎疗效观察

The Clinical Effects of Cortisomol Paste in the Treatment of Chronic Periapical Periodontitis with Concomitant Sinus

目的:观察碧兰根充糊剂一次性根充窦道型慢性根尖周炎的疗效,并与传统的氧化锌碘仿根充糊剂进行比较。方法:选择窦道型慢性根尖周炎患者160例,随机分为实验组(碧兰糊剂)80例,对照组(氧化锌碘仿糊剂)80例,同时在局麻下于窦道开口处实施彻底根尖刮治术,用3%双氧水生理盐水交替冲洗病变区,窦道清刮术后,视情况于窦道内置碘仿细纱条,用碧兰糊剂加牙胶尖(实验组)和氧化锌碘仿糊剂加牙胶尖(对照组)进行根管充填。结果:术后7d内,实验组87.5%患者无不适感,对照组37.5%无不适感,实验组疗效显著高于对照组(P<0.05)。1年的连续观察评价临床疗效,实验组治疗后有效率100%,对照组治疗后有效率96.3%,近期疗效明显高于对照组,远期疗效无显著性差。结论:碧兰根充加根尖刮治治疗窦道型慢性根尖周炎治疗效果满意,临床值得推广。

Objective： To investigate the clinical effects of Cortisomol paste in the treatment of chronic periapical periodontitis with concomitant sinus and compare it with those of ZnO iodoform paste. Methods： 160 cases of chron- ic periapical periodontitis with concomitant sinus were chosen, and randomly divided into experimental group （Corti- somol paste） 80 cases, the control group （zinc oxide iodoform paste） 80 cases. The complete periapical curettage was done under local anesthesia in the sinus opening, and the lesions areas was rinsed with 3% hydrogen peroxide saline by turns. The iodoform bandage strip was placed in the sinus when necessary. Then the root canal fillings were competed gutta percha point with Cortisomo[ paste （the experimental group） or zinc oxide iodoform paste （the control group）. Results： 87.5% of patients had no discomfort in the experimental group, while 37.5% in the con- trol group at 7 day after the treatment （P〈0.05）. After 1-year continuous observation, the long-term effect rate of the experimental group was no higher than that of the control group. Conclusion： ＂The Cortisomol paste for the treatment of chronic periapical periodontitis with concomitant sinus is effective and reliable.
