难治性根尖周炎的病因探讨和治疗方法

The etiology of refractory periapical periodontitis and treatment study

目的探讨难治性根尖周炎的发病原因和治疗方法,评价其治疗疗效。方法选取我院2013年7月~2015年11月收治的难治性根尖周炎患者96例作为研究对象,随机分为对照组和观察组,各48例。对照组进行常规性的治疗,观察组进行非手术根管再治疗-根尖手术联合治疗,观察两组的治疗疗效并分析病因。结果患者接受治疗后2年进行复查,对照组的总有效率为75.00%,观察组的总有效率为95.83%,两组对比,观察组明显优于对照组,差异有统计学意义（P〈0.05）。结论难治性根尖周炎的病因有多种因素,但主要以根尖菌斑生物膜为主,手术根管再治疗-根尖手术联合治疗疗效显著,治愈率高,值得在临床大力推广。

Objective To explore the etiology and treatment of refractory apical periodontitis, and to evaluate the therapeutic efect.methods In our hospital from July 2013 to November 2015 were refractory periapical periodontitis in 96 patients as the research object, randomly divided into control group and observation group, 48 cases in each. The control group was given the conventional treatment, the observation group of non surgical root canal treatment - apical surgery combined treatment, observation and analysis of treatment efficacy of two groups the cause.Results The total effective rate in the control group was 75.00% and the total efective rate in the observation group was 95.83%. Compared with the control group, the observation group was better than the control group （P〈0.05）; the diference was statistically signifcant signifcance.Conclusion The etiology of intractable periapical periodontitis has many factors, with the main apical plaque bioflm-based. The efect of radical resection combined with root canal therapy is signifcant, and the cure rate is high; it is worth to popularize clinically.
