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.
