【摘要】：目的观察ProTaper机用镍钛器械预备弯曲根管的临床效果。方法 180例患者分为两组,每组患牙90个。对照组患牙用不锈钢K锉以标准的逐步深入法进行根管预备;实验组患牙用镍钛机用器械以冠根向深入法进行根管预备。拍摄X线片,观察预备后根管的形态及根管充填效果;记录根管预备后器械折断和变形情况。1周后复诊,评价患牙的疼痛发生率。结果根管预备时间实验组为(3.68±0.82)min,对照组为(10.38±0.32)min;预备后根管不良形态的发生率,对照组为9.32%,实验组为2.30%;根充适充率,对照组为80.51%,实验组为93.12%;根充后疼痛发生率,对照组为37.50%,实验组为10.00%。结论 ProTaper机用镍钛器械器械具有根管成型效果佳、恰充率高、根管预备后疼痛发生率低以及器械折断率低等优点,适用于弯曲根管的预备。
[Abstract]:Objective to observe the clinical effect of preparing curved root canal with nickel titanium instrument in ProTaper machine. Methods 180 patients were divided into two groups, 90 teeth in each group. In the control group, stainless steel K file was used to prepare the root canal by standard step by step method, and in the experimental group, the root canal was prepared by the method of crown and root penetration. X-ray film was taken to observe the shape of the root canal after preparation and the effect of root canal filling, to record the fracture and deformation of the instrument after root canal preparation, and to evaluate the incidence of pain in the teeth. Results the time of root canal preparation was 3.68 卤0.82 min in the experimental group and 10.38 卤0.32 min in the control group, and the incidence of bad root canal morphology was 9.32 in the control group, 2.30 in the experimental group, 80.51 in the control group and 93.12 in the experimental group, and the incidence of post-filling pain was 37.50 in the control group and 10.00 in the experimental group. Conclusion the Ni-Ti instrument used in ProTaper machine has the advantages of good root canal forming effect, high filling rate, low incidence of pain after root canal preparation and low fracture rate, etc. It is suitable for the preparation of curved root canal.
