Abstract： Objective To analyze the clinical significance of sonic instrumentation combined with ProTaper files in canal treatment for residual pulpitis. Methods Totally 78 residual pulpitis cases were randomly divided into the experimental group and the control group.The experimental group were treated with sonic instrumentation combined with ProTaper files，while the control group were treated by ProTaper files. The two groups were treated by calcium hydroxide after medication for 1 week.We compared the reaction of the two groups after root canal preparation of 24h，and root canal filling one week later and the result one year later，and statistics analysis was conducted. Results The reaction of the experimental group was less serious than that of the control group after 24 h and 1 week. The result of the experimental group was better than that of the control group after 1 year. Conclusion Sonic instrumentation combined with ProTaper files is an active and adjunctive therapy for residual pulpitis. The method is simple to use and the long term result is reliable.

摘要：

目的 评价声波根管器械联合ProTaper锉治疗残髓炎的临床疗效。方法 选择2011年2月至2012年2月在南平市妇幼保健院牙体牙髓科门诊就诊的残髓炎患者78例（共78颗患牙），随机分为试验组（41例）和对照组37例。试验组采用声波根管器械联合ProTaper锉进行根管预备，对照组采用单纯的ProTaper锉进行根管预备。两组患者根管预备完成后均用氢氧化钙封药1周，然后行根管充填。比较两组患者根管预备后24 h、根管充填1周后的术后反应及1年后的疗效。结果 试验组患者根管预备后24 h、根管充填1周后的疼痛反应均较对照组轻；试验组1年后的疗效亦优于对照组。结论 声波根管器械联合ProTaper锉治疗残髓炎，可减少预备后的疼痛反应，同时提高根管充填的质量，保证根管治疗的成功率，值得临床推广应用。
