目的:比较一次法根管治疗慢性牙髓炎与慢性根尖周炎的临床疗效。方法:随机选取一次法根管治疗的慢性牙髓炎与慢性根尖周炎病例各24例24个牙,分为两组,慢性牙髓炎为对照组,慢性根尖周炎为治疗组,比较两组治疗后的临床疗效。结果:治疗1周后,对照组有效率为87.5%,治疗组有效率为79.17%,差异无统计学意义(P>0.05),治疗18个月后,对照组有效率为83.33%,治疗组有效率为45.83%,两者有显著差异(P<0.05)。结论:一次法根管治疗慢性牙髓炎与慢性根尖周炎都具有一定的临床疗效,但一次法根管治疗慢性牙髓炎的长期疗效比一次法根管治疗慢性根尖周炎临床疗效好。
Objective: To compare the clinical efficacy of root canal therapy for chronic pulpitis and chronic apical periodontitis. Methods: A total of 24 teeth of 24 patients with chronic pulpitis and chronic apical periodontitis treated by root canal therapy were randomly divided into two groups. Chronic pulpitis was the control group, chronic apical periodontitis was the treatment group, The clinical efficacy of the two groups after treatment was compared. Results: After 1 week of treatment, the effective rate was 87.5% in the control group and 79.17% in the treatment group, with no significant difference (P> 0.05). After 18 months of treatment, the effective rate of the control group was 83.33% The effective rate was 45.83%, there was a significant difference between the two (P <0.05). Conclusion: One-time root canal treatment of chronic pulpitis and chronic apical periodontitis have a certain clinical efficacy, but the long-term efficacy of a root canal treatment of chronic pulpitis than a single root canal treatment of chronic apical periodontitis clinical efficacy it is good.
