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。
Objective To analyze the panoramic features and CT features of total incisor dislocation. Methods Retrospective analysis of 39 cases of clinically confirmed patients with acute maxillofacial injuries and injuries of the teeth of patients. All 39 patients underwent oral panoramic photography and CT examination. Results After the acute maxillofacial trauma, the oral panoramic films diagnosed 26 cases of simple incisor dislocation, 9 cases of incisor dislocation with tooth root fracture, 2 cases suspicious and 2 cases excluded. CT diagnosis of simple incision dislocation in 28 cases, incomplete incontinence with tooth root fracture in 9 cases, incomplete incision incision with alveolar fracture in 2 cases. Conclusions Though oral panoramic dislocation is of high accuracy for dislocation of the tooth, the lateral dislocation of the permanent incisors requires further CT for the definite diagnosis due to the overlapping of the two-dimensional images. The two methods complement each other and greatly improve the diagnostic coincidence rate.
