目的:了解根管预备后疼痛发生率,并对一些可能与疼痛发生有关的因素进行分析.方法:选取2001年7月至2002年2月间武汉大学口腔医院牙体牙髓科完成的非一次法根管治疗纪录表,将相关信息输入计算机后作Chi-square test和logistic回归分析.结果:根管预备后疼痛发生率为11.5%.单因素分析和logistic回归发现身体状况、年龄、牙位于上颌或下颌、术前有无叩痛及牙髓活力为影响疼痛发生率的主要因素.结论:根管预备术后疼痛发生率较低;根管预备术后疼痛发生率受多种因素影响.

Objective:To investigate the incidence of postpreparation pain during root canal therapy(RCT)in a dental teaching hospital and to evaluate the factors affecting the pain experience.Methods:A total of 3512 cases were collected at RCT appointments on demographics,presenting symptoms,treatment procedures and periradicular status.Root canals were conventional instrumented and then medicated.The presence and severity of postpreparation pain after a subsequent endodontic treatment was recorded.The data of postpreparation pain cases were statistically analyzed using the Chi-square test and a multiple logistic regression model.Results:The incidence of postpreparation pain was 11.5%.Analyses of all potential factom revealed that patient age,health status,tooth location,pre-operative percussion pain and pulp status were the factors to significantly influence postpreparation pain experience.Conclusion:The prevalence of postpreparation pain Was low and significantly influenced by multiple factors.
