摘要: 目的 观察直接数字化全景片用于预估根管长度的可靠性。方法 选择已完成根管治疗并摄有数字化全景片的根管191个在专用读片软件Easy Dent 4上测量其长度并估测其工作长度,将测量结果纳入A组,将根管长度测量仪所测长度纳入B组,以B组数据为标准进行分析比较(SPSS18),观察两组数据的相关性和一致性。结果 统计分析显示A、B两组数据有高度相关性:两组数据的误差在1 mm以内的95%的置信区间为(-0.653,0.362)。 结论 直接数字化全景片用于根管长度预估有较高的可靠性,可以用于根管治疗前的初步预估。

Abstract: Abstract: Objective To observe the accuracy of estimating work length by direct digital panoramic. Methods 191 Root-Canal-Therapy-finished canals without symptoms in 3 months after treatment and with preoperative direct digital panoramic view were selected. Easy Dent 4 was used to measure the lengths and estimate the work lengths. The measurements were included into Group A, and the results measured by electronic apex locator Raypex4 (as standards) were included into Group B. The correlation and consistency between Group A and B were observed by SPSS18.0. Results The data of Group A was highly correlated with that of Group B: 95% confidence interval of error within 1mm between Group A and B was (-0.635,0.362). Conclusion Estimating the work length by direct digital panoramic is reliable, which can be used for preliminary estimate before root canal therapy.

Key words: work length estimate direct digital panoramic(DDP)
