目的：观察一次法根管治疗术对老年人前牙慢性根尖炎的疗效。方法：前牙慢性根尖炎老年患者80例，40例采用一次法根管治疗术治疗，40例采用传统多次法根管治疗术治疗，记录两组术后（多次法为第一次术后）24 h、第7天患牙疼痛发生率、同时采集患者上述两时点静脉血2 mL，采用Sysmex全自动血球分析仪检测白细胞（ WBC）计数，散射比浊法测定血清C-反应蛋白（ CRP），观察患牙疼痛发生率、WBC计数、CRP变化及1年后患牙临床疗效。结果：两组患者术后24 h、第7天患牙疼痛发生率、WBC计数、CRP检测比较，差异无统计学意义（P>0.05），1年后临床疗效的评定两组比较，差异无统计学意义（P>0.05）。结论：一次法根管治疗术在老年人前牙慢性根尖炎手术治疗效果与传统多次法相当，值得临床推广。

Objective:To observe the curative effect of single visit root canal therapy in the elderly chronic periapical inflammation of anterior teeth. Methods:Anterior teeth with chronic apical peri-odontitis of 80 elderly patients,40 cases were given one time root canal therapy( group S),40 cases were treated with traditional multiple root canal therapy( group m ),the incidence of dental pain, white blood cell counts,C-reaction protein( CRP)levels in the two groups were observed( after the first operation in group m)in 24h and 7 days after operation,and clinical efficacy was assessed after 1 year. Results:No significant difference was found in the incidence of dental pain,white blood cell count,CRP levels in 24h and 7 days after operation and clinical efficacy between the two groups(P>0. 05 ). Conclusions:One visit root canal therapy has equivalent efficacy with multiple root canal ther-apy in the treatment of elderly chronic apical periodontitis of anterior teeth,and is worth the clinical promotion.
