摘要
目的探讨单支锉系统在后牙一次性根管治疗中的应用价值。方法选取153例拟行后牙一次性根管治疗的患者,以随机数表分为W组、M组和P组,每组各51例。W组采用单支锉系统Wave one Gold进行一次性根管治疗,M组采用连续旋转运动镍钛器械M3-L进行一次性根管治疗,P组采用ProTaper机用镍钛锉进行一次性根管治疗。比较一次根管预备成功率、根管充填质量和适充率,治疗前、治疗1周后和治疗4个月后患牙疼痛评分变化,评价患者的治疗满意度。结果W组、M组和P组一次根管预备成功率分别100.00%、98.04%、82.35%,W组和M组一次根管预备成功率均高于P组(P<0.05);W组和M组适充率分别为100.00%和100.00%,均高于P组(80.39%,P<0.01);治疗1周后和治疗4个月后W组、M组患牙疼痛评分均低于P组(P<0.05),且3组治疗1周后患牙疼痛评分均低于治疗前(P<0.05),4个月后患牙疼痛评分均低于1周后(P<0.05);W组和M组对根管预备、根管填充、根管治疗后的满意度均高于P组(P<0.01)。结论在后牙一次性根管治疗中,单支锉系统中Wave one Gold和M3-L比传统ProTaper机用镍钛锉的根管预备效果更佳,且能提高适充率,减轻疼痛感,提高患者满意度,Wave one Gold和M3-L之间的效果无明显差异。
Objective The aim of this study was to explore the application value of single file system in single-visit root canal therapy of posterior teeth.Methods 153 patients were selected for single-visit root canal therapy of posterior teeth.They were randomly divided into group W,group M and group P with 51 cases in each group.Group W was given single-visit root canal therapy with Wave one Gold in single file system.Group M was given single-visit root canal therapy with reciprocating nickel-titanium instrument M3-L.Group P was given single-visit root canal therapy with ProTaper machine and nickel-titanium file.The success rate of root canal preparation,the quality and filling rate of root canal filling,and the changes inpain score of affected teeth before,after 1 week and 4 months were compared.The patients'satisfaction with treatment was evaluated.Results The success rates of single-visit root canal preparation in group W,M and P were 100.00%,98.04%and 82.35%,respectively.The success rates of single-visit root canal preparation in group W and M were higher than that in group P(P<0.05).The filling rates of group W and M were 100.00%and 100.00%,respectively,higher than that of 80.39%of group P(P<0.01).The pain scores in group W and M after 1 week and 4 months were lower than those in group P(P<0.05).The pain scores in three groups after 1 week and 6 weeks were lower than those before treatment(P<0.05).The pain scores of affected teeth after 4 months were lower than those after 1 week(P<0.05).The pain scores of affected teeth in group W,group after 1 week and 4 months were lower than those in group P(P<0.05).The satisfaction rates of root canal preparation,root canal filling and root canal treatment in group W and group M were higher than those in group P respectively(P<0.01).Conclusion In single-visit root canal therapy of posterior teeth,the Wave one Gold and M3-L in single file system have a better effect on root canal preparation than the traditional ProTaper machine,which can improve the filling rate,reduce pain and achieve patient satisfaction,without a significant difference in effect betweenWave one Gold and M3-L.
