[摘要]目的：探讨根尖手术联合骨组织再生术对慢性根尖周炎患者的治疗效果。方法：选取2016年3月-2019年3月笔者医院诊治的30例慢性根尖周炎患者为研究对象，收集患者资料，进行回顾性分析。患者接受根尖手术后在骨腔内植入骨替代材料，并覆盖生物膜。所有患者均于术后半年内复诊，评价患者术后恢复情况。结果：经术后随访，其中1例患者术后30d内有轻度叩痛，且术后90d内即无明显症状。30例患者均为成功病例，其中好转5例（16.7%），治愈25例（83.3%）。结论：根尖手术联合引导骨组织再生术治疗慢性根尖周炎患者效果显著，满意度较高。

Abstract： Objective  To investigate the effect of root tip surgery combined with bone tissue regeneration on chronic periodontitis inflammation. Methods  Twelve patients with chronic periodontitis who were diagnosed and treated in the author's hospital from March 2016 to March 2019 were selected as the study objects.Patient data were collected for retrospective analysis.Patients underwent root tip surgery with bone replacement material inserted into the bone cavity and biofilm covering.All patients were subsequent visited within half a year after the operation to evaluate their postoperative recovery. Results After postoperative follow-up，One patient had mild knock pain within 30 days after surgery， and the other two had no obvious symptoms within 90 days after surgery.All 12 patients were successful，Among them， 2 cases （16.7%） were improved and 10 cases （83.3%） were cured. Conclusion  Apical surgery combined with guided bone tissue regeneration has a significant effect on the treatment of chronic periodontitis with high patient satisfaction.

根尖周病是指局限于根尖部的牙周組织，如牙周膜、牙骨质及牙槽骨的炎症[1]，又分为急性与慢性根尖周炎，在病理上又分为化脓性和浆液性根尖周炎。慢性根尖周炎的症状较轻，病程长，发展缓慢，往往形成瘘管，经年数月不愈，如产生慢性根尖囊肿，较大者可致使面部变形[2-3]。现今，常使用根尖外科手术来治疗此病，但联合骨组织再生术的案例较少，对其能否增加手术成功率还尚有争议。故此，本研究旨在探讨慢性根尖周炎患者行根尖手术联合骨组织再生术的有效性及安全性，现将结果报道如下。
