目的:观察显微根管治疗牙髓源性牙周牙髓联合病变疗效观察。方法:选用自2014年9月至2016年6月我院收入牙髓源性牙周牙髓联合病变128例,A组64例应用显微根管治疗,B组64例应用传统法,比较两组的治疗效果及复查时探诊深度、出血情况及牙纵裂发生情况。结果:对比两组的治疗效果,应用微创术的A组结果统计明显优于B组,比较两组术后发生牙纵裂的情况,A组可有效降低根管治疗术后并发症,且通过对比术后复查时探诊深度及出血情况,可发现显微根管明显优于传统的治疗方法。结论:显微根管治疗术在用于牙髓源性牙髓牙周联合病变治疗时,其治疗效果比传统方法更佳,应予推广。 Objective: To observe the curative effect of root canal and endodontic pulp combined with micro-root canal therapy. Methods: From September 2014 to June 2016, 128 cases of periodontal and endodontic pulp lesions in our hospital were enrolled, 64 cases in group A were treated with endodontic pulp and 64 cases in group B were treated by traditional method. Group of treatment and review the depth of exploration, bleeding and the occurrence of tooth longitudinal splitting. Results: Comparing the curative effect of the two groups, the result of group A using minimally invasive surgery was obviously better than group B. Comparing the situation of tooth longitudinal split between the two groups, group A can effectively reduce the postoperative complications of root canal therapy By comparing the depth of postoperative exploration and bleeding, can be found significantly better than the traditional micro-root canal treatment. Conclusion: Micro-root canal therapy is more effective than the traditional method in the treatment of periodontal joint lesions of dental pulp origin and should be popularized.
