摘要

目的:比较显微根尖外科手术后短期和长期临床疗效差异并分析原因.方法:从2010-07-2012-12完成显微根尖手术且有1年随访的患者152例患牙207个中,纳入具备完整4年随访资料的患者124例,患牙162个.根据Rud评价标准,对术后1、4年临床及放射学资料进行评估,按1、4年疗效将结果分为成功-成功、成功-失败、失败-成功、失败-失败4组,对比术后1年和4年成功率,并分析成功-失败、失败-成功2组不同观察期愈合结果转变原因及对长期预后的影响因素.结果:术后4年有效随访率78.3%(162/207),术后1年和4年成功率分别为88.3%(143/162)和87.0%(141/162)(P>0.05).成功-失败组的6个患牙,转变原因包括牙周炎、根裂、根面龋损和牙外伤.失败-成功组的4个患牙,转变原因为明确病因后干预治疗.结论:显微根尖外科手术后短期和长期疗效无明显差异.严格手术适应证、规范化操作、避免继发龋和牙外伤等非手术因素,以及失败病例再次手术可以提高显微根尖外科手术的短期和长期疗效.

Abstract

AIM:To evaluate the clinical outcomes of apical microsurgery in short-term and long-term follow-up.METHODS:152 patients with 207 teeth underwent apical microsurgery.Clinical and radiographic evaluations were performed 1 y and 4 y after surgery according to Rud's criteria.Based on the follow-up results,the cases were divided into 4 groups,as success-success group,success-failure group,failure-success group and failure-failure group.Cases with different success rates at 1 y and 4 y follow-up were compared,the causes of change and factors of long-term prognosis were analysed.RESULTS:A total of 124 patients with 162 teeth were completed 4 y follow-up (78.3% recall rate).The success rates of 1 y and 4 y follow-up were 88.3% (143/162) and 87.0% (141/162) respectively (P>0.05).6 teeth were classified as success-failure group.Failure reasons at 4 y follow-up were periodontitis,vertical root fracture,secondary caries and traumatic dental injury.4 teeth were classified as failure-success group and the reason of success at 4 y follow-up was interventional treatment after failure reason was found.CONCLUSION:There was no significant difference between the short-term and long-term clinical outcomes after apical microsurgery.1 year outcome can basically predict the long-term prognosis.Strict selection of surgical indications,standardized operation,avoidance of secondary caries and dental trauma can improve the outcomes of apical microsurgery.
