目的:比较超声根管治疗仪与常规的人工根管预备治疗法在一次性根管治疗中的临床疗效,以选出较好的根管治疗方法。方法:将我院自2012年8月至2013年6月期间收治的98例需要进行牙髓治疗的患者作为研究对象,收集到患牙117颗,随机分为对照组(55颗)和超声组(62颗),对照组采用常规的人工机械操作预备根管,对照组采用超声根管治疗仪预备根管,预备好根管后进行一次性根管填充治疗。术后观察根管治疗的时间和术后疼痛发生率,对两种方法进行评价。结果:超声组的手术时间和术后疼痛发生率与对照组相比有显著性差异(P<0.05)。结论:相比传统人工机械操作治疗,使用超声根管治疗仪可以有效缩短手术时间,减少术后患者的疼痛感,操作简便实用,适合在临床上推广使用。
OBJECTIVE: To compare the clinical efficacy of ultrasonic root canal therapy instrument and routine artificial root canal preparation in one-time root canal therapy to select better root canal therapy. Methods: From September 2012 to June 2013 in our hospital, 98 cases of patients requiring endodontic treatment were enrolled. 117 teeth were collected and randomly divided into control group (55) and ultrasound group (62). In the control group, the conventional root canal preparation was performed by manual mechanical operation. The control group was prepared by root canal treatment. The root canal was prepared and filled with root canal. After operation, the time of root canal treatment and the incidence of postoperative pain were observed, and the two methods were evaluated. Results: The operative time and the incidence of postoperative pain in the ultrasound group were significantly different from those in the control group (P <0.05). Conclusion: Compared with the traditional operation of artificial mechanical treatment, the use of ultrasonic root canal therapy instrument can effectively shorten the operation time and reduce postoperative pain perception, simple and practical, suitable for clinical use.
