目的:比较两种根管糊剂治疗慢性窦道型根尖周炎的临床疗效。方法:选择慢性窦道型根尖周炎379例,随机分为Cor-tisomol糊剂组191例和传统根管糊剂组188例。两组分别采用Cortisomol糊剂与传统根管糊剂行一次性根管治疗,治疗后7天、30天及1年分别比较两组及其不同年龄段的临床疗效。结果:(1)治疗后7天,Cortisomol糊剂组患牙窦道愈合率为88.0%,显著高于传统根管糊剂组的73.3%(P<0.05)。≥60岁年龄段中,Cortisomol糊剂组患牙窦道愈合率显著高于传统根管糊剂组(P<0.05);<60岁年龄段中,两组比较,差异不显著(P>0.05)。(2)治疗后30天,Cortisomol糊剂组患牙根尖愈合优级者占88.5%,传统根管糊剂组占86.1%;两组比较,差异不显著(P>0.05)。≥60岁年龄段及<60岁年龄段中,两组患牙根尖愈合优级者构成比比较,均差异不显著(P>0.05)。(3)治疗后1年,Cortisomol糊剂组治疗成功率为95.3%,传统根管糊剂组为92.0%;两组比较,差异不显著(P>0.05)。≥60岁年龄段及<60岁年龄段中,两组治疗成功率比较,均差异不显著(P>0.05)。结论:在治疗慢性窦道型根尖周炎方面,Cortisomol糊剂较传统根管糊剂短期内能更有效促进窦道愈合,远期疗效较好,老年患者适宜采用Cortisomol糊剂。
Objective: To compare the clinical effects of two kinds of root canal paste in the treatment of chronic sinusoid apical periodontitis. Methods: A total of 379 cases of chronic sinusoidal periapical periodontitis were randomly divided into Cor-tisomol paste group (n = 191) and traditional root canal paste group (n = 188). The two groups were treated with Cortisomol paste and traditional root canal paste one-time root canal therapy, respectively. The clinical effects of two groups and their different ages were compared at 7 days, 30 days and 1 year after treatment. Results: (1) The healing rate of sinusoids in Cortisomol paste group was 88.0% 7 days after treatment, which was significantly higher than that of the traditional root canal paste group (73.3%, P <0.05). In the 60-year-old group, the healing rate of the sinus of the Cortisomol paste group was significantly higher than that of the traditional root canal paste group (P <0.05); in the 60-year-old group, the difference was insignificant (P> 0.05 ). (2) 30 days after treatment, 88.5% of patients with C root tip healing in Cortisomol paste group and 86.1% in traditional root canal paste group showed no significant difference (P> 0.05). In the group of ≥60 years old and <60 years old, there was no significant difference between the two groups (P> 0.05). (3) One year after treatment, the successful rate of Cortisomol paste group was 95.3% and that of traditional root canal paste group was 92.0%. There was no significant difference between the two groups (P> 0.05). ≥60 years of age and <60 years of age, the treatment success rate of the two groups were not significantly different (P> 0.05). Conclusion: Cortisomol paste can promote sinus healing more effectively than conventional root canal paste in the treatment of chronic sinusoid apical periodontitis, and the long-term curative effect is better. Cortisomol paste is suitable for elderly patients.
