摘　　要：目的探讨iRoot SP单尖充填技术用于根管再治疗的临床效果。方法选取2021年2月至2022年1月于长沙市口腔医院行根管再治疗的96例患者作为研究对象,根据随机数字表法将其分为研究组(n=48)和参考组(n=48)。研究组行iRoot SP单尖充填,参考组行AH-Plus热牙胶垂直加压法充填。比较两组的根管充填效果、单根管填充时间、疼痛程度、疗效、咀嚼功能。结果两组的根管充填效果比较,差异无统计学意义(P>0.05)。研究组的单根管填充时间为(58.88±5.21)s,短于参考组的(92.35±7.24)s,差异有统计学意义(P<0.05)。研究组术后1、7 d的视觉模拟评分法(VAS)评分为(4.28±0.79)分、(2.97±0.35)分,均低于参考组的(6.54±2.02)分、(3.87±1.21)分,差异有统计学意义(P<0.05);两组的疗效及治疗总有效率比较,差异无统计学意义(P>0.05);术后,两组患者的咀嚼效率、咬合力均高于本组术前,且研究组的咀嚼效率、咬合力均高于参考组,差异有统计学意义(P<0.05)。结论根管再治疗使用iRoot SP单尖充填技术可在确保疗效的同时缩短填充时间,减轻患者疼痛,改善咀嚼功能,值得临床推广使用。Objective To explore the clinical effect of iRoot SP single-tip filling technique for root canal retreatment.Methods A total of 96 patients who underwent root canal retreatment in Changsha Stomatological Hospital from February 2021 to January 2022 were selected as the research objects.According to random number table method,they were divided into study group(n=48)and reference group(n=48).The study group was filled with iRoot SP single-tip,and the reference group was filled with AH-Plus hot gutta-percha vertical compression method.The effect of root canal filling,single root canal filling time,pain degree,curative effect and masticatory function were compared between the two groups.Results There was no significant difference in the effect of root canal filling between the two groups(P>0.05).The filling time of single root canal in the study group was(58.88±5.21)s,which was shorter than(92.35±7.24)s in the reference group,and the difference was statistically significant(P<0.05).The visual analogue scale(VAS)scores of the study group were(4.28±0.79)points and(2.97±0.35)points,both lower than(6.54±2.02)points and(3.87±1.21)points of the reference group,and the differences were statistically significant(P<0.05).There were no significant differences in the efficacy and total effective rate between the two groups(P>0.05).After operation,the masticatory efficiency and bite force of the two groups were higher than those before operation,and the masticatory efficiency and bite force of the study group were higher than those of the reference group,and the differences were statistically significant(P<0.05).Conclusion The application of iRoot SP single-tip filling technique in root canal retreatment can ensure the curative effect,shorten the filling time,relieve the pain of patients,and improve the masticatory function,which is worthy of clinical application.
