不锈钢K锉根管与ProTaper镍钛旋转器械根管治疗牙体牙髓病对比

Comparison of stainless steel K-file root canal and ProTaper nickel titanium rotating instrument root canal treatment of dental pulp disease

目的:探讨不锈钢K锉根管与ProTaper镍钛旋转器械根管治疗牙体牙髓病的应用价值。方法:选取2011年1月至2016年12月收治的180例牙体牙髓病患者,随机将患者分为观察组和对照组,每组90例,观察组采用ProTaper镍钛旋转器械根管治疗,对照组采用不锈钢K锉根管治疗,对比两种方法的治疗效果。结果:观察组根管预备成功率为100.0%(90/90),高于对照组90.0%(81/90)(χ2=4.237,P=0.043);治疗前疼痛视觉模拟评分法(VAS)评分组间差异无统计学意义(t=0.875,P=0.334),治疗后两组评分均降低(P<0.05),并且治疗后观察组评分低于对照组(t=3.432,P=0.005);观察组满意度为95.6%(86/90),高于对照组的80.0%(72/90)(χ2=10.683,P=0.004)。结论:ProTaper镍钛旋转器械根管治疗牙体牙髓病,具有根管预备成功率高、患者疼痛缓解以及患者治疗满意度较高等优点。

Objective： To investigate the clinical value of stainless steel K - file root canal and ProTaper nickel titanium rotating instrument root canal in the treatment of dental pulp disease. Methods： 180 cases of patients with dental pulp disease enrolled in our hospital from January 2011 to December 2016 were selected and divided into observation group and control group according to the random number table method, 90 cases in each group. The observation group was treated with ProTaper nickel titanium rotating instrument mot canal treatment, and the control group was treated with stainless steel K - file root canal. The therapeutic effects of the two methods were compared. Results： The success rate of root canal preparation in observation group was 100 % （90/90） , higher than that in control group （90 %, 81/90）, and the difference was statistically significant （χ^2 = 4. 237, P = 0. 043 ）. Before treatment, there was no significant difference in VAS score between the two groups （ t = 0. 875, P = 0. 334）. After treatment, the scores of the two groups were decreased, and the scores of the observation group after treatment were lower than those of the con- trol group, the difference was statistically significant （ P 〈 0.05 ）. The satisfaction rate was 95.6 % （86/90） in the observation group and 80 % （72/90） in the control group, and the difference was statistically significant （χ^2 = 10.683, P = 0. 004 ）. Conclusion：PreTaper nickel titanium rotating instrument root canal treatment of dental pulp disease has the advantages of the higher root canal preparation success rate, greater degree of pain relief and higher satisfaction rate of the treatment.
