目的:研究和探讨在根管治疗的临床过程中,分别采用三种方法进行弯曲根管预备的临床效果。方法:随机抽选我院2015年02月~2016年02月以来,口腔科门诊收治的105例进行根管治疗的患者。按照数字表法将患者平均分为A、B、C三组,每组各有患者35例。分别采用不锈钢K锉、超声波机扩系统以及镍钛机扩系统进行弯曲根管的预备,并就三组患者的临床治疗情况进行统计、比较和分析。结果:统计学对比显示,C组患者在预备时间、根管成型以及术后反应方面均依次优于B组和A组患者,C、B两组同A组之间的对比差异性显著,均存在显著性差异(P<0.05)。结论:在根管治疗中采用镍钛机或超声波机的临床效果均较佳,在临床治疗时可以根据患者需求进行恰当选择。
OBJECTIVE: To study and discuss the clinical effect of using three methods to prepare curved root canal in the clinical course of root canal therapy. Methods: A total of 105 patients undergoing root canal therapy were included in our department from February 2015 to February 2016 in our hospital. According to the digital table method, the patients were equally divided into A, B, C three groups, each with 35 patients in each group. The preparation of curved root canal with stainless steel K-file, ultrasonic expansion system and nickel-titanium expansion system were performed respectively. The clinical treatment of the three groups were statistically analyzed, compared and analyzed. Results: Statistical analysis showed that the patients in group C were superior to those in group B and group A in terms of preparation time, root canal formation and postoperative response, and the differences between group C and group B were significant There was a significant difference (P <0.05). Conclusion: The clinical effect of nickel-titanium machine or ultrasonic machine in root canal therapy is better, and can be properly selected according to the needs of patients in clinical treatment.
