【摘要】：目的:评价三种不同运动模式的镍钛器械联合热牙胶充填技术用于下颌后牙一次法根管治疗的近期疗效观察。方法:将375名于我院就诊年龄为19~68岁且被诊断为慢性根尖周炎的汉族患者纳为研究对象,共375颗下颌后牙(包括第一、二前磨牙及第一、二磨牙),随机分为3组:WaveOne往复运动组,ProTaper Universal连续旋转运动组和Twisted File Adaptive自适应运动组,每组125例研究对象。所有研究对象均采用冠根向法进行根管预备,3%次氯酸钠超声荡洗根管,干燥根管,热牙胶垂直加压技术进行根管恰填。比较三组镍钛器械根管预备平均操作时间;分析一次法根管治疗术后24h、72h及7d的疼痛情况;评价三组患者术后3个月的近期效果。结果:WaveOne组根管预备平均操作时间为(2.14±1.07)min,Twisted File Adaptive组根管预备平均操作时间为(3.08±1.19)min,ProTaper Universal组根管预备平均操作时间为(4.03±1.73)min,三组镍钛器械根管预备平均操作时间差异有统计学意义(P0.001);术后24h及72h三组行一次法根管治疗术后疼痛率差异有统计学意义(P0.05),术后7d三组术后疼痛率无统计学差异(P0.05);比较三组一次法根管治疗术后3个月的有效率差异无统计学意义(P0.05)。结论:WaveOne组进行根管预备时间最短,能够提高预备效率;Twisted File Adaptive组进行根管预备,可明显降低术后疼痛反应;WaveOne组和Twisted File Adaptive组术后3个月进行疗效评价,近期临床效果显著。新型镍钛器械进行根管预备,对于感染根管而言可实现一次法根管治疗,对临床推广具有一定意义。
[Abstract]:Objective: to evaluate the short-term curative effect of three different movement-mode nickel-titanium instruments combined with hot gum filling technique in the treatment of mandibular posterior teeth with one-time root canal. Methods: a total of 375 mandibular posterior teeth (including first, second premolar and first premolar) were selected from 375 Han nationality patients aged 1968 and diagnosed as chronic periapical periodontitis. Two molars were randomly divided into three groups: ProTaper Universal continuous rotation group and Twisted File Adaptive adaptive motion group. All the subjects were used to prepare the root canal by the method of crown and root direction. The root canal was washed by ultrasonic with 3% sodium hypochlorite, the root canal was dried and the root canal was filled with hot gum vertical pressure technique. The mean operating time of root canal preparation was compared among the three groups, the pain at 24 hours and 7 days after root canal treatment was analyzed, and the short-term effect of 3 months after operation was evaluated in the three groups. Results the mean operating time of root canal preparation was (2.14 卤1.07) min Twisted File Adaptive group (3.08 卤1.19) min ProTaper Universal group was (4.03 卤1.73) min, there was significant difference among the three groups (P0.001). There was significant difference in postoperative pain rate between the three groups at 24 hours and 72 hours after treatment (P0.05), but there was no significant difference in postoperative pain rate in the three groups on the 7th day after operation (P0.05). There was no significant difference in the effective rate between the three groups after 3 months of once root canal therapy (P0.05). Conclusion the root canal preparation time of the 1: WaveOne group is the shortest, which can improve the preparation efficiency. The root canal preparation in the Twisted File Adaptive group can significantly reduce the postoperative pain response and evaluate the curative effect 3 months after operation in both the WaveOne group and the Twisted File Adaptive group. The short-term clinical effect is remarkable. A new type of Nickel-titanium instrument for root canal preparation can be used for the treatment of root canal infection, which is of significance for clinical application.
