OBJECTIVE
This paper discussed the dredging effect and safety of ethylenediaminetetraacetic acid (EDTA) combined with C-pilot files and microultrasound (mUS) on root canal calcification.
METHODS
From October 2021 to January 2022, 132 patients with calcified root canals treated in our hospital were selected as the research subjects. Among them, 64 cases who received EDTA combined with C-pilot Files and mUS plus ultrasonic instruments to dredge calcified root canals were regarded as the research group (RG), and another 68 cases given ultrasonic instruments plus C-pilot files were regarded as the control group (CG). The root canal dredging time was recorded, and the dredging success rate and total success rate of different tooth positions and calcification sites were compared between groups. The clinical efficacy was assessed 6 months after treatment. Pain severity was evaluated by the Pain Intensity Numerical Rating Scale (PI-NRS) before (0), during (1), and after treatment (2). Finally, the incidence of adverse reactions within one week after treatment was counted.
RESULTS
RG was observed with statistically higher success rates of root canal dredging in different tooth positions and calcified sites than CG ( < 0.05). Besides, the total effective rate of treatment was 92.19% in RG, which was also higher compared with CG, while the root canal dredging time in RG was shorter than that in CG ( < 0.05). Increased NRS scores were found in both groups at 1, and the score in RG was significantly lower compared with that in CG. At 2, both groups showed a lower PI-NRS score than 1 but higher than 0, and the score at 2 was also lower in RG as compared to CG ( < 0.05). Moreover, the reduced incidence of adverse reactions were observed in RG compared with CG ( < 0.05).
CONCLUSIONS
EDTA combined with C-pilot files and mUS can effectively improve the dredging success rate of root canals obstructed by calcification, shorten the dredging time, and improve patient comfort, which is an effective method for clinical dredging of calcification obstructed root canals.
目的
本文探讨了乙二胺四乙酸（EDTA）联合 C 型锉和微超声（mUS）对根管钙化的疏通效果和安全性。
方法
选取 2021 年 10 月至 2022 年 1 月在我院接受钙化根管治疗的 132 例患者作为研究对象。其中，64 例行 EDTA 联合 C 型锉和微超声加超声器械疏通钙化根管的患者作为研究组（RG），68 例行超声器械加 C 型锉疏通的患者作为对照组（CG）。记录根管疏通时间，比较两组不同牙位和钙化部位的疏通成功率和总成功率。治疗后 6 个月评估临床疗效。采用疼痛强度数字评分量表（PI-NRS）评估治疗前后（0、1、2）疼痛严重程度。最后，统计治疗后 1 周内不良反应的发生率。
结果
RG 在不同牙位和钙化部位的根管疏通成功率均明显高于 CG（<0.05）。此外，RG 的治疗总有效率为 92.19%，高于 CG，而 RG 的根管疏通时间短于 CG（<0.05）。两组 1 时 NRS 评分均升高，且 RG 评分明显低于 CG。2 时，两组 PI-NRS 评分均低于 1，但高于 0，且 RG 评分低于 CG（<0.05）。此外，RG 的不良反应发生率低于 CG（<0.05）。
结论
EDTA 联合 C 型锉和微超声能有效提高钙化阻塞根管的疏通成功率，缩短疏通时间，提高患者舒适度，是钙化阻塞根管临床疏通的有效方法。
