Repair of an Extensive External Cervical Resorption Lesion Using Intentional Replantation with Crown Rotation

Figure 2

Radiographic images taken during the patient’s initial visit to the University Clinic. (a) Intraoral radiographic image. A large translucency was suggestive of ECR at the maxillary right lateral incisor, extending from the distal to the mesial side, can be observed. It was difficult to accurately determine the buccal-to-palatal extent of ECR. The pulp chamber appeared narrowed adjacent to the ECR lesion. (b) Selected horizontal and para-sagittal images of CBCT volume. 3D observation by CBCT shows that external resorption of the cervical area of the tooth was more pronounced on the palatal side and was diagnosed as a type 2Bp according to Patel’s classification. The numbers given in the figure indicate a cross-sectional view of each line of that number.
