摘要:目的  探讨iRoot SP糊剂用于根管再治疗的疗效。方法  选取2016年5月~2017年12月我院接受非手术性根管再治疗患者158例(患牙174颗),采用随机数字表法分为A组和B组,每组87例。A组使用iRoot SP糊剂,B组使用AH-Plus糊剂,两组患牙放置根管充填糊剂后,均采用热牙胶连续波垂直加压法充填根管,比较两组治疗48 h、10 d后疼痛反应以及6个月、1年临床疗效。结果  治疗后48 h,A组疼痛率低于B组(8.05% vs 24.14%),差异有统计学意义(P<0.05);治疗后10 d,两组疼痛率比较(5.75% vs 11.49%),差异无统计学意义(P>0.05)。治疗后6个月、1年,A组成功率均高于B组,但差异无统计学意义(P>0.05)。结论  iRoot SP糊剂用于根管再治疗可减轻根管再治疗患牙充填后的急性疼痛,并且远期疗效稳定。

Abstract:Objective  To investigate the efficacy of iRoot SP paste for root canal retreatment. Methods  From May 2016 to December 2017, 158 patients (174 teeth) were treated with non-surgical root canal therapy. The patients were divided into group A and group B by random number table, 87 cases in each group. Group A used iRoot SP paste, group B used AH-Plus paste, two groups of teeth placed root canal filling paste, were filled with hot tooth gel continuous wave vertical compression method, compared with two groups for 48 h treatment the pain response after 10 d and the clinical efficacy of 6 months and 1 year. Results  At 48 h after treatment, the pain rate in group A was lower than that in group B (8.05% vs 24.14%), the difference was statistically significant (P<0.05). The pain rate was compared between the two groups (5.75% vs 11.49%) at 10 d after treatment,the difference was not statistically significant (P>0.05). At 6 months and 1 year after treatment, the power of A was higher than that of group B, but the difference was not statistically significant(P>0.05). Conclusion  iRoot SP paste for root canal retreatment can reduce the acute pain after root canal retreatment for tooth filling, and the long-term effect is stable.

牙齿的根管系统错综复杂,有文献报道,目前根管治疗技术的成功率为40%~97%[1],而导致治疗失败最直接的原因是根管内部感染病灶清除不彻底,根管治疗失败的首选补救方案为非手术性根管再治疗,旨在清除根管内残余感染灶,重建根尖周组织的健康[2]。有研究显示[3],使用具有组织相容性良好、抗菌作用明显的根管封闭材料能够明显提高根管再治疗的成功率,减轻术后反应,临床远期效果稳定。AH-Plus糊剂由糊剂A(环氧化物树脂、钨酸钙盐、氧化锆、二氧化硅、氧化铁色素)和糊剂B(胺、钨酸钙盐、氧化锆、二氧化硅、硅树脂油)组成,具有良好的尺寸稳定性、低溶解性及一定的自粘性,但易出现超填现象,导致根充术后疼痛等并发症。iRoot SP糊剂的主要成为为氧化锆、硅酸钙、磷酸钙、氢氧化钙、填料和增稠剂,其具有优秀的生物相容性,生物活性,和无细胞毒性。本文主要探讨iRoot SP糊剂用于根管再治療的临床疗效,现报道如下。
