目的:观察超声波法与手工法在预备细窄根管清理中的应用,评价其临床效果。方法:选取2014年1月——2017年3月为时间段,对此时段在我院门诊部收集的58颗单根恒牙进行对比研究,采取数字表随机法分为A组与B组各29颗,给予A组手工根管清理,B组给予超声波法根管技术清理,观察两组牙齿清理情况。结果:经清洗后数据统计显示,较之A组,B组在细窄根管尖1/3区、颈1/3区清洁效果明显更优,差异具有统计学意义(P<0.05),而在中1/3区两组清洁效果差异不大(P>0.05)。结论:在预备细窄根管清理中采用超声波法根管技术清理较之常规手工根管清理效果更优,有助于提高清理杀菌效果,具有临床应用与推广价值。
OBJECTIVE: To observe the application of ultrasonic and manual methods in the preparation of narrow root canal cleaning, evaluate its clinical effect. Methods: From January 2014 to March 2017, we selected 58 single root permanent teeth collected from outpatient clinics of our hospital for comparison in this period, and divided them into group A and group B 29, A group of manual root canal cleaning, B group given ultrasonic root canal technique to clean, observe the two groups of teeth cleaning. Results: After cleaning, the data showed that the cleaning effect of Group A was significantly better than that of Group A and B (P <0.05), and the difference was statistically significant (P <0.05) There was no significant difference between the two groups in the area of 1/3 (P> 0.05). Conclusion: It is better to clean the prepared root canal with ultrasonic root canal in the preparation of thin narrow root canal, which is better than the conventional manual root canal cleaning. It is helpful to improve the sterilization effect and has the clinical application and popularization value.
