摘　　要：目的对比研究乳牙急性根尖周炎首诊开放和封药两种治疗方法对缓解患儿疼痛和消除牙周肿胀的情况。方法选取我院儿童齿科乳磨牙急性根尖周炎100例。随机分为髓腔开放组和髓腔封药组各50例。髓腔开放组:常规打开髓腔,H锉拔髓,清除髓室和根管内感染坏死组织,冲洗根管,降低咬合,髓腔内留置棉球开放;髓腔封药组:常规打开髓腔,清除感染坏死组织,K锉根管预备至35号以上,冲洗根管,渗出较少后根管内封CP(樟脑酚)棉球。观察24 h疼痛缓解和7d炎症消除情况。结果首诊治疗后24 h内,髓腔开放组疼痛缓解49例,未缓解1例;髓腔封药组疼痛缓解42例,未缓解8例。两者比较差异有统计学意义(P<0.05)。7 d后复诊,髓腔开放组肿胀消除39例,髓腔封药组肿胀消除47例,两者比较有显著统计学意义(P<0.05)结论乳牙急性根尖周炎首诊开放在短时间内缓解疼痛效果优于根管封药,但是根管封药在消除炎症方面优于髓腔开放,并有利于减少复诊次数。Objective To evaluate the incidence of pain and inflammation after treating acute apical periodontitis of deciduous teeth using pulp open or cover treatment at the first time. Methods 100 patients with acute apical periodontitis were randomly allocated to two groups. One was pulp open group,and the other was cover treatment group,50 cases in each group. In the pulp open group,the dental cavity was conventionally opened,the dental pulp was extracted using H file,the pulp chamber and infected sloughs in the root canal were cleaned,then the root canal was douched,the occlusion was lowered,and the dental cavity was open with cotton ball in. In the cover treatment group,the dental cavity was conventionally opened,inflected sloughs were eliminated,K file was used for root canal preparation to No. 35,then the root canal was douched,and was covered with CP（ camphor phenol） cotton ball after the exudation became low.The relief of pain at 24 th h and of inflammation on 7th d were observed. Results There were obviously difference between two groups about pain and on the changes of inflammation. Conclusions The treatment by opened can reduce the pain in a short time,but the cover treatment can effectively prevent to develope into chronic periodontitis during root canal therapy on acute apical periodo ntitis.
