OBJECTIVE
To evaluate the application of hand-use ProTaper instruments in endodontic treatment of molar canals.
METHODS
A total of 203 permanent molars were randomly divided into the experimental group (99 molars) and control group (104 molars) prepared by hand-use ProTaper instruments and standard stainless steel K-file, respectively. The molars in the two groups were obturated by cold lateral condensation technique. The root canal preparation and obturation were evaluated by radiograph, and the working time of preparation and post-operative emergencies were analyzed.
RESULTS
The preparation time in the experimental group was obviously shorter than that in the control group (P<0.01). The rate of satisfactory effect was significantly higher in the experimental group than in the control group (P<0.01), and the rate of post-operative emergencies was significantly lower in the experimental group (P<0.01).
CONCLUSION
The application of hand-use ProTaper instruments may improve the effect of root canal treatment of the molars and shorten the working time and reduce the post-operative emergencies.
目的
评估手动使用ProTaper器械在磨牙根管治疗中的应用。
方法
将203颗恒牙随机分为实验组（99颗磨牙）和对照组（104颗磨牙），分别采用手动使用ProTaper器械和标准不锈钢K锉进行预备。两组磨牙均采用冷侧方加压技术进行充填。通过X线片评估根管预备和充填情况，并分析预备工作时间和术后急症情况。
结果
实验组的预备时间明显短于对照组（P<0.01）。实验组的满意效果率显著高于对照组（P<0.01），且实验组的术后急症率显著低于对照组（P<0.01）。
结论
手动使用ProTaper器械的应用可能会提高磨牙根管治疗的效果，缩短工作时间并减少术后急症。
