【摘要】：目的:评价联合应用声波根管器械与机用Mtwo镍钛锉对磨牙进行根管预备的临床疗效。方法:选取符合纳入标准的患者100例(第一磨牙118颗,共428个根管),按就诊顺序抽签随机分为2组,每组各50例。试验组联合应用声波根管器械与机用Mtwo镍钛锉进行根管预备,对照组采用传统不锈钢根管锉进行根管预备,2组均采用冷侧压法充填根管,观察2组根管预备时间、预备术后急症反应、根管充填质量及根充后1 a复查的治疗成功率。采用SPSS11.0软件包进行统计学分析。结果:试验组根管预备时间平均为(5.3±0.6)min/根,对照组平均为(12.7±0.9)min/根,差异显著(t=100.89,P0.001);试验组根管预备术后急症反应发生率为8.20%,显著低于对照组的22.81%,差异显著(χ2=4.87,P0.05);试验组根管恰填率为92.86%,对照组为78.92%,差异显著(χ2=17.45,P0.05);根管充填后1 a的治疗成功率试验组为91.80%,对照组为78.95%,2组间差异显著(χ2=3.95,P0.05)。结论:联合应用声波根管器械与机用Mtwo镍钛锉预备根管比传统不锈钢根管锉省时,术后疼痛反应减少,根充效果及治疗成功率提高。
[Abstract]:Objective: to evaluate the clinical effect of combined use of acoustic root canal instruments and Mtwo nickel titanium file for root canal preparation of molars. Methods: 100 patients (118 first molars, 428 root canals) were randomly divided into 2 groups, 50 in each group. The experimental group used sonic root canal instrument and Mtwo nickel titanium file for root canal preparation, the control group used traditional stainless steel root canal file for root canal preparation, the two groups used cold lateral pressure method to fill root canal, and observed the preparation time of root canal in two groups. Emergency response, root canal filling quality and successful rate of treatment 1 year after root filling were prepared. SPSS11.0 software package was used for statistical analysis. Results: the mean root canal preparation time was (5.3 卤0.6) min/ in the experimental group and (12.7 卤0.9) min/ in the control group. The incidence of emergency reaction after root canal preparation in the experimental group was 8.20, which was significantly lower than that in the control group (22.81%, 蠂 2 4.87 P 0.05). The root canal filling rate was 92.86 in the experimental group and 78.92 in the control group (蠂 ~ 2 / 17.45). One year after root canal filling, the successful rate of treatment was 91.80 in the experimental group and 78.95 in the control group (蠂 ~ 2 / 3.95). Conclusion: compared with the traditional stainless steel root canal file, the combined use of sonic root canal instrument and Mtwo nickel titanium file for root canal preparation can save time, reduce postoperative pain response, and improve the effect of root filling and the success rate of treatment.
