【摘要】 目的分析恒切牙不全脱位的口腔全景和CT特点。方法回顾性分析39例临床证实的因急性颌面部创伤而伤及牙齿的患者资料。39例均经过口腔全景摄片和CT检查。结果急性颌面部创伤后,口腔全景片确诊单纯切牙不全脱位26例,切牙不全脱位伴牙根骨折9例,可疑2例,排除2例。CT确诊单纯切牙不全脱位28例,切牙不全脱位伴牙根骨折9例,切牙不全脱位伴牙槽骨折2例。结论口腔全景虽对于牙不全脱位准确性高,但对于恒切牙侧方不全脱位,因二维图像前后重叠,需要进一步CT进行明确诊断,两种检查方法相互弥补,大大提高诊断符合率。更多还原

【Abstract】 Objective To analyze the features of panoramic oral radiogram and CT in traumatic permanent incisor subluxation. Methods 39 cases were retrospectively analyzed who were clinically confirmed due to acute maxillofacial trauma injuried and teeth,all of the 39 cases received the oral panoramic radiography and CT examination. Results After acute maxillofacial trauma,26 case were confired with simple incisor subluxation,incisor subluxation with 9 cases of root fracture,2 cases of suspected subluxation,2 cases of negatived subluxation. Dental CT diagnosis of pure incisor subluxation 28 cases,incisor subluxation with 9 cases of root fracture,incisor subluxation with alveolar bone fractures in 2 cases. Conclusion Although oral panorama for tooth subluxation accuracy is high,yet for the permanent incisor lateral subluxation,because 2-D image overlap,before and after the need to further make clear diagnosisby CT,two inspection methods make up for each other to improve the diagnostic coincidence rate.更多还原
