摘　　要：目的：探讨根管治疗上乳切牙（BA｜AB/｜）根尖周炎伴牙冠缺损的疗效。方法：对2010年1月—2012年12月收治的114例（162颗）上乳切牙根尖周炎伴牙冠缺损患儿进行根管治疗。根据牙冠缺损原因分成龋病组（85颗）和外伤组（77颗）。162颗患牙中2～3岁患儿的患牙75颗,3～4岁患儿的患牙87颗。用日本森田公司Vitapex糊剂进行根管治疗,1年后进行疗效比较。结果：1年随访总治愈率为62.35%,外伤组治愈率低于龋病组,差异有统计学意义（P〈0.01）。2～3岁组治愈率低于3～4岁组,差异有统计学意义（P〈0.05）,不同性别、松动度和有无窦道患牙的治愈率差异均无统计学意义（P〉0.05）。结论：有外伤史的上乳切牙根尖周炎根管治疗远期疗效低于单纯龋病引起的上乳切牙根尖周炎。Objective：To investigate the efficacy of root canal therapy for periapical periodontitis of maxillary primary incisors accompanied by crown defects.Methods：A total of 114 children patients with periapical periodontitis of maxillary primary incisors（162）accompanied by crown defects,who were admitted for root canal therapy during January 2010 and December2012,were allocated into the caries group（85incisors）and the trauma group（77incisors）according to whether they had trauma history or not.Among them,there were 75 incisors from2-3 years group and 87 incisors from3-4 years group.The efficacy analysis were conducted after one year root canal therapy with Vitapex calcium hydroxide paste from J.Morita Corporation.Results：The total cure rate was 62.35% during one year follow-up.The cure rate in trauma group was lower than that in the caries group,and the difference was statistically significant（P〈0.01）.The cure rate of 2-3 years group was lower than that of 3-4 years group,and the difference was statistically significant（P〈0.05）.There was no significant difference regarding cure rate among children with different genders or mobility degrees,as well as with or without sinus（P〉0.05）.Conclusions：The long term efficacy of root canal therapy for periapical periodontitis of maxillary primary incisors with traumatic history is inferior to that for periapical periodontitis of maxillary primary incisors caused by caries.
