摘　　要：目的探讨ProTaper镍钛系统冠向下根管预备对老年根管再治疗患者术后疼痛的影响。方法将137例接受根管再治疗的老年患者采用数字表法随机分为镍钛锉组(n=71)和不锈钢锉组(n=66),2组均采取相同的术前准备,镍钛锉组利用ProTaper Universal再治疗器械(D1、D2、D3)将根管填充物去除,用ProTaper(F1、F2、F3)开展根管预备;不锈钢锉组采用不锈钢锉进行预备。分析2组患者术后1、6、12、24、48、72h和7d时自评疼痛情况,并于患者24h和7d复诊时,按照Mohd Sulong标准对患者疼痛进行评估。结果 2组患者性别、年龄、患牙位置、术前视觉模拟评分(VAS)、术前根尖周指数、根管治疗难度系数差异均无统计学意义(P>0.05)。镍钛锉组术后6、12、24、48、72h时VAS自评分分别为(1.27±0.56)、(2.31±1.38)、(1.69±0.93)、(1.61±0.31)分,均低于不锈钢锉组的(4.18±1.93)、(4.75±1.53)、(3.27±1.28)、(1.89±0.49)分,差异均有统计学意义(t=11.234、8.523、9.514、3.942,均P<0.05);镍钛锉组术后24h复诊时疼痛率11.3%,显著低于不锈钢锉组的31.8%,差异有统计学意义(χ2=8.657,P<0.05);镍钛锉组术后7d复诊时疼痛率2.8%,低于不锈钢锉组的4.5%,但差异无统计学意义(P>0.05)。结论 ProTaper镍钛系统冠向下根管预备可有效减少老年根管再治疗患者术后疼痛的发生。ObjectiveTo investigate the effect of ProTaper NiTi systems crown-down root canal preparation on postoperative pain in elderly endodontic retreatment patients.Methods137 cases of elderly patients accepted endodontic retreatment were randomly divided into NiTi file group(n=71)and stainless steel file group(n=66).The two groups of patients were taken the same preoperative preparation.Patients in NiTi file group were utilizing ProTaper Universal machine retreatment system(D1,D2,D3)to remove the root canal fillings,and carried out root canal preparation by using ProTaper(F1,F2,F3).Patients in stainless steel file group were taken stainless steel file preparation.After surgery 1,6,12,24,48,72 h and 7d,the self-assessment of pains of the patients were recorded.When patients returned at 24 h and 7 d,the pains were assessed according to Mohd Sulong criteria.ResultsThe differences of gender,age,tooth position,preoperative visual simulation score(VAS),preoperative periapical index and root canal therapy difficulty factor between the two groups were no statistically significant(P>0.05).The VAS scores of patients in NiTi file group at 6,12,24,48 and 72 h after surgery were(1.27±0.56),(2.31±1.38),(1.69±0.93),(1.61±0.31),which were lower than stainless steel file group,which were(4.18±1.93),(4.75±1.53),(3.27±1.28),(1.89±0.49),the differences were statistically significant(t=11.234,8.523,9.514,3.942,P<0.05).The pain rate of patients 24 h after surgery in NiTi file group was 11.3%,which was significantly lower than 31.8%of the stainless steel file group,the difference was statistically significant(χ2=8.657,P<0.05).The pain rate of patients 7 d after surgery in NiTi file group was 2.8%,which was less than 4.5%of the stainless steel file group,but the difference was not statistically significant(P>0.05).ConclusionProTaper NiTi crown-down root canal system could effectively reduce postoperative pain in elderly endodontic retreatment patients.
