单支锉根管预备联合iRoot sp单尖法充填用于一次性根管治疗的临床观察

Clinical observation of single-file root canal preparation combined with iRoot sp single-tip method for one-time root canal treatment

摘要

摘要:
目的： 探讨单支锉根管预备联合iRoot sp单尖法一次性根管充填治疗慢性根尖周炎临床效果。
方法： 选取100例慢性根尖周炎拟行一次性根管治疗的病人，以随机数表分为研究组（W组）和对照组（P组），每组各50例（患牙50颗）。W组采用单支锉系统Wave one Gold进行根管预备联合iRoot sp单尖法根管充填。P组采用Protaper Gold进行根管预备联合AH Plus热牙胶垂直加压法根管充填。比较2组一次性根管预备成功率、单根管预备时间、单根管充填时间、根管充填质量，术后疼痛情况，术后6个月复查结果，对比2组病人根管治疗有效率。
结果： W组根管预备成功率明显高于P组（P ＜ 0.05）；W组根管预备时间明显少于P组（P ＜ 0.01）；W组适充率高于P组（P ＜ 0.01）；单根管充填所需时间W组明显少于P组（P ＜ 0.01）；2组术后24 h VAS评分比较差异无统计学意义（P ＞ 0.05）。术后48 h和72 h，W组VAS评分低于P组（P ＜ 0.01）。半年后复查，W组有效率高于P组（P ＜ 0.05）。
结论： 慢性根尖周炎患牙采用一次性根管治疗，单支锉系统Wave one Gold 根管预备联合iRoot sp单尖法充填比较Protaper Gold根管预备AH Plus热牙胶充填，前者根管预备、根管充填用时更少，适充率更优，术后疼痛发生率较低且轻，术后6个月复查效果更佳。

Abstract:
Objective To investigate the clinical effects of single-file root canal preparation combined with iRoot sp single-tip root canal filling in the treatment of chronic periapical inflammation.
Methods A total of 100 patients with chronic periapical periodontitis scheduled by one-time root canal treatment were randomly divided into the study group (group W) and control group (group P) 50 patients (teeth) each group. The W group were treated with root canal preparation of single file system Wave one Gold combined with iRoot sp single tip method. The P group were treated with Protaper Gold root canal preparation combined with AH Plus hot gum vertical compression method. The success rate of one-time root canal preparation, single canal preparation time, single canal filling time, root canal filling quality and postoperative pain between two groups were compared. Two groups were re-examined after 6 months of surgery, and the effectiveness of root canal treatment was compared between two groups.
Results The success rate of root canal preparation in the W group was significantly higher than that in P group (P ＜ 0.05). The root canal preparation time in the W group was significantly less than that in P group (P ＜ 0.01). The filling rate in the W group was higher than that in P group P (P ＜ 0.01). The time required of single canal filling in the W group was significantly less than that in P group (P ＜ 0.01). There was no statistical significance in the VAS scores after 24h of operation between two groups (P ＞ 0.05). The VAS scores in the W group were lower than those in P group at 48h and 72 h after operation (P ＜ 0.01). Six months later, the effective rate in the W group was higher than that in P group (P ＜ 0.05).
Conclusions Compared with Protaper Gold root preparation and AH Plus hot glue filling, the single file system Wave one Gold root preparation combined with iRoot sp single tip method for one-time root canal treatment for teeth with chronic periapical inflammation takes less time in the root canal preparation and filling, has good filling rate and low and mild postoperative pain incidence, and the treatment results are better at 6 months after surgery.
