摘要: 目的：探讨热牙胶垂直加压充填技术治疗下颌第二磨牙C形根管的疗效及安全性。方法：选取84例经X线片发现C形根管的下颌第二磨牙病变病人，采用数字表法分为对照组和观察组，各42例。对照组病人采用常规冷牙胶侧压法充填C形根管进行治疗，观察组病人采用热牙胶垂直加压充填技术进行治疗。对比2组临床治疗效果及根管治疗后并发症的发生情况。结果：观察组病人的总有效率优于对照组（P<0.01）；观察组病人治疗适填率92.86%，高于对照组的71.43%（P<0.05）；观察组病人在根管治疗的根充时间、患牙填充材料与根尖区的距离方面均明显优于对照组（P<0.01）；观察组病人并发症发生率9.52%，明显低于对照组的33.33%（P<0.01）。结论：对C形根管的下颌第二磨牙病变病人采用热牙胶垂直加压充填技术，可改善牙痛、牙龈肿胀等不适症状，同时恢复牙齿正常咀嚼功能，患牙填充材料与根尖区封闭较为良好，治疗后并发症的发生率低。

Abstract: Objective:To investigate the efficacy and safety of hot gutta percha vertical pressure filling technology in the treatment of C shaped root canal in mandibular second molar.Methods:Eighty-four patients with C shaped root canal lesion in mandibular second molar diagnosed by X-ray were randomly divided into the control group and observation group using numerical digit method(42 cases each group).The C shaped root canal in control group and observation group were treated with the conventional cold gutta percha lateral pressure filling technology and hot gutta percha vertical pressure filling technology,respectively.The clinical effects and incidence of complications after root canal treatment between two groups were compared.Results:The clinical efficacy in observation group was better than that in control group(P<0.01).The proper fill rate in observation group(92.86%) was higher than that in control group(71.43%)(P<0.05).The filling root time,filling material and distance between apical region in observation group were significantly better than those in control group(P<0.01).The incidence rate of complications in observation group (9.52%) was significantly lower than that in control group(33.33%)(P<0.01).Conclusions:Hot gutta percha vertical pressure filling technology for C shaped root canal in mandibular second molars can improve the toothache,gingival swelling and other symptoms,and restore the normal chewing function of teeth.The closeness in dental filling material and apical area are good,and the incidence of postoperative complications is low. -
