摘要/Abstract

摘要： 目的:分析比较偏位投照与锥形束CT(CBCT)在根管治疗中发现遗漏根管的应用。方法:对200例患牙常规拍摄术前正位根尖片和CBCT,术中插诊断丝拍摄20°～30°偏位投照根尖片,完善根管治疗。比较偏位投照与CBCT发现的遗漏根管数,采用SPSS 19.0软件包对数据进行统计学分析。结果:200例患牙中,偏位投照发现8例患牙有遗漏根管,前牙及前磨牙3例,磨牙5例。而CBCT扫描显示有15例,其中,前牙及前磨牙4例,磨牙11例。CBCT发现数量大于偏位投照,但差异无显著性(P>0.05)。结论:偏位投照与CBCT有利于发现遗漏根管,帮助临床完善根管治疗。

Abstract: PURPOSE: To compare the accuracy of angulated periapical radiography and cone beam computed tomography (CBCT) in the detection of missing root canals. METHODS: Before endodontic treatment, 200 teeth were scanned by CBCT and taken conventional periapical radiographs at the routine angle. During the root canal treatment, the radiograph was taken at an angle of 20-30 degree from the mesial or distal of the teeth with files in canal and the diagnosis of missing canals by angulated periapical radiography was compared with the image of CBCT. The data was analyzed using SPSS19.0 software package. RESULTS: Among the 200 teeth, missing canals were displayed in 8 cases by angulated periapical radiography, among which 3 were anterior teeth and 5 were molars. There were 4 anterior teeth and 11 molars with missing canals were found in CBCT. But the difference between the two methods was not significant(P>0.05). CONCLUSIONS: The angulated periapical radiography and CBCT will assist the clinician in detection of missing root canals.
