根管治疗期间急症的发生原因和处理

目的探讨根管治疗期间急症的发生原因及其治疗方法。方法对55例根管治疗期间急症的患牙进行临床分析。用地塞米松和甲硝唑行根管内封药,1周后用Vitapex糊剂加牙胶尖行根管充填;术后随访1a,评价其疗效。结果根管治疗期间急症的发生率为12.59%(55/437)。牙髓炎组(5.13%)与牙髓坏死、根尖周炎组(16.73%)的急症发生率差异有显著性(P<0.01),前牙组与后牙组发生率差异有显著性(P<0.01)。随访1年时疗效评定为成功者达92.7%。结论根管治疗期间急症的发生与术前患牙的牙髓状况、牙位等有关;用地塞米松和甲硝唑行根管内封药及用Vitapex糊剂加牙胶尖行根管充填治疗,效果可靠。

Clinical Study on the Causes and Treatment of Endodontic Interappointment Emergencies

Objective To investigate the causes and the treatment of endodontic interappointment emergencies.Meth-ods An analysis were made for55teeth with endodontic interappointment emergencies.The root canals were sealed with dexamethasone and metronidazole,and filled with Vitapex add gutta-percha point after one week.An evaluation of curative effect was made after following up one year.Results The total incidence of endodontic interappointment emergencies was12.59%(55/437).There was significant difference between pulpitis and pulp necrosis or apicitis(P<0.01).There was signifi-cant difference between anterior teeth and posterior teeth(P<0.01).The success rate was92.7%after following up one year.Conclusion The cause of endodontic interappointment emergencies was related to pulp status and tooth location,etc.The treatment that sealed the root canals with dexamethasone and metronidazole and filled with Vitapex add gutta-percha point is of availability.
