【摘要】：背景:一次法根管治疗的已受到临床医生的广泛认可,新型的镍钛器械可以提高工作效率,提高治疗效果与舒适度,符合患者的心理需求,同时也可以有效地减轻医生的工作负担。目的:评价3种不同运动模式镍钛器械联合热牙胶充填技术在一次法根管治疗中的临床疗效。方法:将375例诊断为牙髓坏死或根尖周炎的患者,375颗患牙,随机分为3组:Wave One往复运动组,Pro Taper连续旋转运动组和Twisted File Adaptive自适应运动组,均采用冠向下法进行根管预备,给予超声荡洗后,予以连续波热牙胶垂直加压充填。结果与结论:3组根管预备时间差异有显著性意义(P0.001),其中Wave One往复运动组用时最短,Pro Taper连续旋转运动组用时最长。3组根管适充率无显著性意义(P0.05)。术后24和72 h,3组疼痛率差异有显著性意义(P0.05)。术后7 d,3组疼痛率差异无显著性意义(P0.05)。说明相比较而言使用Wave One进行根管预备效率最高,成形效果好,而Twisted File Adaptive镍钛器械可显著降低术后疼痛。
[Abstract]:Background: the primary root canal therapy has been widely accepted by clinicians. The new Ni-Ti device can improve the working efficiency, improve the therapeutic effect and comfort, and meet the psychological needs of the patients.At the same time, it can also effectively reduce the burden of work of doctors.Objective: to evaluate the clinical effect of three different sports models of nickel titanium instruments combined with hot gum filling in the treatment of one-time root canal.Methods: three hundred and seventy-five teeth were randomly divided into three groups: the Twisted Taper continuous rotation exercise group and the Twisted File Adaptive adaptive exercise group. The root canal preparation was performed by coronal downward method.After ultrasonic washing, continuous wave hot gum vertical compression filling was given.Results there was a significant difference in root canal preparation time between the three groups, and there was no significant difference in the filling rate of root canal in the Wave One reciprocating exercise group with the shortest time and the longest time in the Wave Taper continuous rotation group.There was significant difference in pain rate between 24 and 72 hours after operation (P 0.05).There was no significant difference in pain rate among the 3 groups 7 days after operation (P 0.05).The results showed that the root canal preparation with Wave One had the highest efficiency and good shaping effect, while the Twisted File Adaptive nickel titanium instrument could significantly reduce postoperative pain.
