摘要
目的:评估手动ProTaper根管扩大系统联合镍钛K锉对弯曲根管治疗的效果。方法:103例病人103个患牙随机分为两组,实验组53个,用手动ProTaper根管扩大系统和镍钛K锉进行根管预备,对照组50个,用不锈钢K锉预备,两组均以常规侧方加压法进行根管充填,在治疗前、中、后应用数字牙片了解根管数目形态、确定根管工作长度、判断治疗效果。结果:对103个患牙根管充填后拍摄数字牙片及观察术后反应,实验组根管成形及充填满意率88.68%,术后急性反应率为1.89%。对照组满意率64%,术后急性反应率为14%。经χ2检验进行分析,两组根管成形及充填满意率有显著性差异(P<0.01),术后急性反应率有显著性差异(P<0.01),实验组明显优于对照组。结论:手动ProTaper根管扩大系统联合镍钛K锉可有效改善弯曲根管治疗的效果。
AIM： To assess the application of hand ProTaper in combination with nikel - titanium alloy k - file in endodontic treatment of curved root canals. METHODS： 103 teeth of 103 patients included in the study were divided into two groups randomly. 53 teeth were instrumented by hand ProTaper and nikel - titanium alloy K - file in the test. 50 teeth were instrumented by stainless steel K - files for control. All teeth were obturated with lateral condensation method. The efficiency of preparation and obturation was analyzed with digital radiographs before, during and after operation. RESULTS： The data of radiographical results of the 103 teeth after obturation were recorded. The acute reaction rate of 103 patients were analyzed by χ2 test. Satisfactory radiographical results of the test group with rate of 88.68% were obtained , which was significantly higher than 64% of the control（ P 〈 0.01 ）. The acute reaction rate was 1.89% , which was significantly lower than 14% of the control（ P 〈0.01 ）. CONCLUSION： Hand ProTaper in combine with nikel -titanium alloy k - file efficiently enhanced the successful rate in endodontic treatment of curved root canals.
