摘　　要：目的:探讨MSCT Dental技术在外伤后前牙区隐匿性根折法医学鉴定中的作用。方法:选择外伤后可疑前牙区根折而普通X线牙片和曲面断层片难以确诊的患者28例,行MSCT扫描及Dental技术图像重组,获得专业全景图及剖面图。结果:28例49颗牙齿存在根折,其中单颗牙根折18例,多颗牙根折10例;中切牙根折39颗,侧切牙根折10颗;8例合并冠折;9例合并邻近牙槽突骨折;10例合并邻牙损伤,其中6例为牙齿缺如,4例为冠折。结论:MSCT Dental技术在外伤后前牙区隐匿性根折法医学鉴定中具有重要意义。Objective:To investigate the role of MSCT Dental technique in forensic medicine identify of occult root fracture in anterior teeth after trauma.Methods:A total of 28 cases suspected with root fractures in anterior teeth after trauma were collected.All cases were difficult to diagnosis by conventional dental film and panoramic tomography.MSCT scanning and Dental image reconstruction were performed for all cases.Results:There were 49 teeth of root fracture in 28 patients,including 18 single and 10 multiple root fractures.There were 39 middle incisor root fractures and 10 lateral incisor root fractures.8 cases were observed with crown fractures,9 with adjacent alveolar process fractures,10 with adjacent teeth injuries,in which 6 cases were tooth absences and 4 crown fractures.Conclusion:MSCT Dental technique can play an incomparable role in forensic medicine identify of occult root fracture in anterior teeth after trauma.
