摘　　要：目的:比较慢性根尖周炎一次性根管治疗和多次性根管治疗的临床疗效。方法:选择2009年1月至6月慢性根尖周炎的患者105例,患牙178颗。将此105例患牙随机分为2组,分别采用一次性根管治疗法和多次性根管治疗法进行治疗;观察治疗后第3天和第7天疼痛发生率和1年后治疗效果。结果:治疗后3天内的疼痛发生率一次性根管治疗组高于多次根管治疗组;治疗后7天的疼痛发生率两组差异没有统计学意义。1年后随访两组患牙治疗的成功率,差异无统计学意义。结论:一次性根管治疗和多次性根管治疗对慢性根尖牙周炎均有较好的临床效果;但一次性根管治疗能明显减少患者的就诊时间和次数,值得在临床推广。[Objective]To compare the therapeutic effects between Single-visit and traditional root canal therapy for chronic apical periodontitis.[Method]105 cases were randomly divided into two groups:study group treated with root canal therapy in single visit and control group with multiple root canal therapy.The pain intensity within 1 and 3 week and therapeutic effects within 1 year after treatment was evaluated.[Result]Compared with multiple-visit root canal therapy,single-visit root canal therapy has much higher incidence of pain on the 3rd day.However,no obvious difference is found on the 7th day as well as treatment effect after 1 year.[Conclusion]Both Single-visit root canal therapy and multiple root canal therapy have good treatment effect on the chronic apical periodontitis.However,the former could reduce the time and frequency of visits for the patients, and is more recommended.
