摘要：

目的    对比观察氢氧化钙和甲醛甲酚用于根尖周炎患牙根管内封药的疗效。方法    选择2008年1月到2009年12月在中国医学科学院整形外科医院口腔中心就诊的135例牙根尖周炎患者的156颗患牙，随机分为A组（81颗）和B组（75颗）。步退法根管预备后分别于根管内封入氢氧化钙（A组）和甲醛甲酚（B组）进行消毒。于封药后1周、根充后1周和治疗后3个月对两组疗效进行观察并作出相应评价。结果    根管封药后1周A组的有效率为92.59%，B组的有效率为78.67%，两组间差异有统计学意义（P＜0.05）；根管充填后1周，A、B两组的急症发生率（3.70% 对12.0%）差异有统计学意义（P＜0.05）。治疗后3个月A组的成功率为91.36%；B组为84.00%，两组间差异有统计学意义（P＜0.05）。结论    氢氧化钙用于根尖周炎患牙根管内消毒的疗效优于甲醛甲酚。

Abstract:

Objective    To study the disinfecting effects of calcium hydroxide and formocresol on fistula periapical periodontitis in root canals of infected teeth. Methods    A total of 156 teeth with fistula periapical periodontitis were divided into two groups. Group A （81 cases） was disinfected using calcium hydroxide and Group B （75 cases） using formocresol. Both types of disinfectants were put into root canals by using step-back techniques，and their therapeutic effects were examined at different time later. Results    Both disinfectants led to alleviation or disappearance of toothache. The therapeutic effect of calcium hydroxide was better （92.59%） than that of formocresol （78.67%） in a week. The teeth with root canal therapy emergencies （RCTE） in group B were more than in group A during and after root canal therapy. There was statistical significance in the effect of the two groups. Conclusion    For teeth with fistula periapical periodontitis calcium hydroxide is a relatively suitable root canal disinfectant.
