1. Ameloblastoma between teeth 32 and 33
A well-defined predominantly radiolucent multilocular lesion is present in the interradicular region of teeth 32 and 33. The roots of teeth 32 and 33 have been splayed by the entity. No periapical pathology is present at either tooth, which suggests that these teeth are not the source of the lesion. Expansion of the buccal and lingual cortical plates has occurred. This radiographic appearance is suggestive of the presence of a benign odontogenic tumor. Innumerable small loculations are present at the alveolar crest, which is an appearance more suggestive of an ameloblastoma than an odontogenic keratocyst.
Axial views of teeth 32 and 33
These axial cross-sectional images demonstrate the absence of any root resorption or damage to the splayed roots of teeth 32 and 33, as well as the buccolingual expansion of the alveolar process in the interradicular region of these two teeth by the benign tumor. The presence of many small loculations in the superior region of the tooth is also evident in these images.
Buccolingual views of teeth 32 and 33
These buccolingual cross-sectional images demonstrate the well-defined corticated periphery of the expansile benign lesion in the interradicular region of teeth 32 and 33.
Mesiodistal views of anterior 3rd quadrant
These mesiodistal cross-sectional images demonstrate the multilocular appearance of the lesion in the interradicular region of the roots of teeth 32 and 33. The mesial displacement of the root of tooth 32 by the lesion is evident in these images. The superior border of the lesion extends through the crest of the alveolar process.
Orthogonal views of tooth 32
These orthogonal cross-sectional images demonstrate the normal appearance of the apical foramen of tooth 32, as well as the absence of any root resorption or damage to the tooth, despite the mesial displacement of the tooth by the tumor that is positioned distally to it.
Orthogonal views of tooth 33
These orthogonal cross-sectional images demonstrate the normal appearance of the root of tooth 33. No signs of root resorption or damage are present. The apical foramen of the tooth appears normal.
