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。
Objective To evaluate the clinical efficacy of acoustic root canal instruments combined with ProTaper file in the treatment of patients with residual myelitis. Methods From February 2011 to February 2012, 78 patients (78 teeth) with residual myelitis from the Department of Endodontics, Nanping Maternal and Child Health Hospital were randomly divided into experimental group (41 cases) and control group Group of 37 cases. In the test group, root canal preparation was performed by using acoustic root canal instrument combined with ProTaper file and control group by simple ProTaper file for root canal preparation. Two groups of patients after root canal preparation are completed with calcium hydroxide sealed for 1 week, and then root canal filling. The postoperative response of root canal at 24 hours after root canal preparation and one week after root canal filling were compared between two groups. The curative effect after one year was compared. Results The pain response of the experimental group 24 h after root canal preparation and 1 week after filling the root canal was lighter than that of the control group. The efficacy of the experimental group after 1 year was also better than that of the control group. Conclusion Acoustic root canal instruments combined with ProTaper file for the treatment of myelitis can reduce the postoperative pain response, improve the quality of root canal filling and ensure the success rate of root canal therapy, which is worthy of clinical application.
