1. Recurrent ameloblastoma in right mandible
There is a well-defined, corticated, multilocular radiolucency extending from the interradicular bone between teeth 45 and 46 to the midline. The distal aspect of this entity abuts the right mental foramen. This lesion has caused thinning and expansion of the buccal and lingual cortices of the mandible. The buccal cortex apical to teeth 44 and 45 is dehiscent. The lingual cortex overlying the root apices of teeth 43 and 45 is also dehiscent. This lesion has caused resorption of the roots of teeth 43, 44, and 45, as well as displacement of teeth 43 and 44. These findings suggest the presence of an odontogenic neoplasm. Given the patient's reported history of an ameloblastoma in the right mandible, the most likely interpretation is that of a recurrent ameloblastoma.
2. Secondarily affected tooth 42
The lesion in the right mandible abuts the root apex of tooth 42. There is no evidence of root resorption or displacement due to this lesion, however. The remaining periradicular bone appears normal.
3. Secondarily affected tooth 43
The lesion in the right mandible abuts the entire distal root surface and apex of tooth 43. Tooth 43 has been displaced mesially. Resorption is present on the root apex of tooth 43. The remaining periradicular bone appears normal radiographically.
4. Secondarily affected tooth 44
The lesion in the right mandible abuts the coronal two thirds of the mesial root surface, the apical third of the distal root surface, and the apex of tooth 44. Tooth 44 has been displaced distally, but the crown of the tooth is mesially tipped. Resorption is present on the mesial root surface of the tooth. The remaining periradicular bone appears normal.
5. Secondarily affected tooth 45
The lesion in the right mandible abuts the apex and palatal surface of the apical third of the root of tooth 45. The apex of the root of tooth 45 is resorbed. This tooth has not been displaced. The remaining periradicular bone appears normal radiographically.
6. Dystrophic calcification in left chin
Dystrophic calcification is present in the subcutaneous tissues overlying the left chin. This is a non-significant incidental finding.
