摘要:

背景:多项研究表明Hero642是一种安全性能较高的机用镍钛锉,其根管成形能力良好。
目的:评价Hero642镍钛机动器械一次性根管治疗的临床效果。
方法:选择400例牙髓炎或根尖炎患者,分别采用Hero642镍钛机动器械和手用镍钛根管锉进行一次性根管治疗,记录根管预备时间、患牙治疗后1周疼痛情况,并评价2年后根管治疗效果,计算治疗后1周疼痛率和治疗2年后的成功率。
结果与结论:Hero642镍钛机动器械组平均单根管预备时间为(3.57±0.76) min,手用镍钛根管锉组为(7.62±0.25) min,两组根管预备时间比较差异有显著性意义(P < 0.01);Hero642镍钛机动器械组和手用镍钛根管锉组治疗后1周疼痛的发生率分别3.5%和22.8%,两组间比较差异有显著性意义(P < 0.01);治疗后2年Hero642镍钛机动器械组和手用镍钛根管锉组治疗成功率分别为94.4%,92.4%,两组治疗效果比较差异无显著性意义。表明采用Hero642镍钛机动器械进行一次性根管治疗时间短、术后反应小,效果良好。

Abstract:

BACKGROUND: Several studies have shown that Hero642 is a rotary nickel-titanium file with high safe performance, and its ability of root canal shaping is good.
OBJECTIVE: To observe the clinical effect of single-visit root canal treatment using Hero642 nickel-titanium rotary instrument on teeth with chronic pulpitis and apical periodontitis.  
METHODS: Totally 400 teeth with chronic pulpitis and apical periodontitis were operated by Hero642 nickel-titanium rotary instrument and nickel-titanium hand file, respectively. The efficiency of root canal preparation was taken. Pain reactions were recorded 1 week after operation and curative effects were evaluated 2 years after root canal treatment. Rates of pain and success were calculated at 1 week and 2 years after treatment, respectively. 
RESULTS AND CONCLUSION: The average time for root canal preparation was (3.57±0.76) minutes in the Hero642 group and (7.62±0.25) minutes in the hand file group, and there was a significant difference between the two groups (P < 0.01). After 1 week of treatment, the pain rates were 3.5% and 22.8% in the two groups, respectively, showing a significant difference (P < 0.01). Two-year follow-up was performed, and ratios of success were 94.4% in the Hero642 group and 92.4% in the hand file group, but there was no difference between the two groups. Hero642 nickel-titanium rotary instrument for single-visit root canal treatment showed excellent efficiency on clinical treatment, reduced treatment period and had less postoperative reactions.
