目的:探讨一次性根管治疗慢性根尖周炎的临床效果。方法:选取2011年2月～2011年10月我院口腔门诊收治的慢性根尖周炎患者30例,分为观察组(n=15)与对照组(n=15),观察组采用一次性根管治疗,根管预备后行牙胶尖蘸氧化锌根管充填剂侧方加压术充填根管;对照组采用多次根管治疗,根管预备后封入氢氧化钙糊剂,复诊无症状后再行根管填充。观察两组患者的治疗成功率。结果:两组比较,差异无统计学意义(P>0.05)。结论:慢性根尖周炎的一次性根管治疗远期疗效等同于多次根管治疗,在选择好适应证的情况下,一次性治疗方法具有一定的临床意义。
Objective: To investigate the clinical effect of one-time root canal therapy on chronic apical periodontitis.
