目的探讨热牙胶垂直加压充填磨牙弯曲根管的临床疗效。方法选取2011年3月-2013年3月我院口腔科治疗的患有牙髓病和根尖周病且根管弯曲的恒磨牙180颗,随机分为两组各90颗。观察组90颗恒磨牙120个根管采用垂直加压技术进行热牙胶根管充填,对照组恒90颗磨牙126个根管采用冷牙胶侧方加压根管充填。观察并比较术后疼痛的发生情况、根管充填的恰填率和成功率。结果观察组与对照组术后疼痛发生率无显著差异(P>0.05);观察组根管充填恰填率、治疗成功率均高于对照组,组间差异有统计学意义(P<0.05)。结论采用热牙胶垂直加压充填磨牙弯曲根管的临床疗效显著,值得推广。
Objective To investigate the clinical effect of hot teethers loaded vertically on curved curved root canal. Methods 180 permanent molar with endodontic and periapical periodontitis and root canal bending treated in our department from March 2011 to March 2013 were randomly divided into two groups of 90 each. In the observation group, 120 root canals of 90 permanent molars were filled with hot gutta-percha canal, while the control group of 90 permanent molars with 126 root canals were filled with cold tamponade lateral pressure root canal. Observe and compare the incidence of postoperative pain, root canal fill the correct rate and success rate. Results There was no significant difference in the incidence of postoperative pain between the observation group and the control group (P> 0.05). The filling rate of root canals and the success rate of treatment in the observation group were all higher than those in the control group (P <0.05) . Conclusion The clinical effect of using hot gutta-percha vertical compression filling of curved root canal is significant and worthy of promotion.
