目的探讨感染性根管一次性根管治疗的临床疗效。方法将芜湖市中医医院2009年2月到2010年6月之间收治的43例采取感染根管一次性根管治疗的牙髓坏死和慢/急性根尖周炎患者(75颗患牙)和同期的47例采取感染根管二次性根管治疗的牙髓坏死和慢/急性根尖周炎患者(83颗患牙)的临床效果进行对比分析,观察两组的患者术后的疼痛情况和临床治疗效果情况。结果通过两组的治疗效果对比,观察组的患者术后1周的疼痛率与对照组的患者术后1周的疼痛率比较无明显的差异(P>0.05)。观察组的患者在术后3、6、12个月的治疗效果与对照组的比较无明显的差异(P>0.05),统计学无意义。结论临床中采取感染根管一次性根管治疗具有较好的应用效果,有效的缩短患者的临床治疗时间,减少患者就诊次数,值得在临床中推广应用。
Objective To investigate the clinical effect of disposable root canal therapy of infectious root canal. Methods A total of 43 patients with pulpal necrosis and chronic / acute apical periodontitis (75 teeth) underwent one-time root canal therapy with infected root canal were treated in Wuhu Hospital of Traditional Chinese Medicine from February 2009 to June 2010 In the same period, 47 patients with pulp root necrosis and acute / chronic apical periodontitis (83 teeth) treated with root canal infection were compared and analyzed. The postoperative pain was observed in both groups And the clinical treatment of the situation. Results There was no significant difference (P> 0.05) in the pain rate of the patients in the observation group between one week after operation and the control group after one week of operation. There was no significant difference in the treatment effect between the observation group and the control group at 3, 6 and 12 months after operation (P> 0.05), which was statistically insignificant. Conclusions The clinical application of root canal therapy with infected root canal has a good application effect, effectively shortening the clinical treatment time and reducing the frequency of patient visits, which is worth popularizing in clinic.
