目的:用氢氧化钙糊剂与甲醛甲酚作为慢性根尖周炎的根管消毒剂,比较在根管治疗中分别封入此两种药物消毒根管期间急症发生的差异性。方法:患有慢性根尖周炎恒牙共260颗,随机分为两组,记录临床症状、体征,摄X片、常规根管预备后,分氢氧化钙组和甲酚甲醛组;一周后复诊应用临床根尖周指数(CPI)进行疗效评定,观察疗效。结果:氢氧化钙组(A组)根管治疗期间急症的发生率明显低于甲醛甲酚组(B组)(P<0.01),两组有显著性差异。结论:氢氧化钙糊剂作为根管消毒剂,可减少慢性根尖周炎根管治疗过程中急症的发生。
OBJECTIVE: To compare the difference of acute emergency between root canal therapy and root canal therapy by using calcium hydroxide paste and formaldehyde cresol as root canal disinfectant for chronic apical periodontitis. Methods: A total of 260 permanent permanent apical periodontitis patients with chronic apical periodontitis were randomly divided into two groups. Clinical symptoms, signs, radiographs and routine root canal preparation were recorded. Calcium hydroxide group and cresol formaldehyde group were divided into two groups. Clinical apical week index (CPI) to evaluate the curative effect. Results: The incidence of acute illness during root canal therapy of calcium hydroxide group (A group) was significantly lower than that of formaldehyde cresol group (P <0.01). There was significant difference between the two groups. Conclusion: Calcium hydroxide paste as a root canal disinfectant can reduce the occurrence of emergency in the treatment of chronic apical periodontitis.
