摘要： 目的:根据数字化X线片图像,分析根管治疗规范化操作培训前后根管充填质量的变化。方法:收集我科4名从事牙体牙髓病学的临床医师在2009年9月~2010年9月和2010年11月~2011年11月完成的根管治疗病例,采用分层随机抽样方法进行抽样,对两组根管充填质量进行比较分析。结果:A组(规范化操作组)总体患牙和根管适充率分别为64.9%和72.6%,明显高于B组(习惯性操作组)的45.1%和54.3%,两者之间具有显著性差异(P<0.001)。A组患牙和根管适充率在不同牙位均显著高于B组(P<0.05)。B组不同牙位出现台阶形成的总体比例为20.7%,A组下降为14.2%,两者差异具有显著性(P<0.05)。结论:规范化操作可提高临床医生的根管治疗水平。

Abstract: Objective: To evaluate the role of standardized manipulation in endodontics by comparing the quality of root canal filling before and after standardized manipulation training, according to the digital radiography. Methods: Using stratified random sampling method a total of 598 endodontically treated teeth with 1208 roots, which were completed by four dentists, were retrospectively studied. The quality of root canal filling was analysed radiographically according to the length, density, and taper of root fillings, meanwhile the presence of overfilling and ledge formation was recorded for each root canal. Results: The overall percentages of adequate teeth filling and root canals filling after taking standardized manipulation training were 64.9% and 72.6% respectively, which were significantly higher than those before taking standardized manipulation. Meanwhile, regardless of anterior teeth, premolars or molars, the percentages of adequate teeth filling and root canals filling after taking standardized manipulation were significantly higher. The overall rate of ledge formation before taking standardized manipulation were 20.7%, which was declined to 14.2% after taking standardized manipulation. The difference between the two groups was statistically significant. Conclusion: The quality of root canal filling was improved greatly after taking standardized manipulation.
