1. Benign odontogenic cystic lesion at site 38
A well-defined cystic lesion is present at site 38. This entity has caused the lingual expansion of the alveolar process, and has produced multiple dehiscences in the lingual cortical plate. The alveolar crestal bone is also dehiscent adjacent to the entity. This lesion has effaced the lamina dura at the distal surface of tooth 37, but has not caused any significant root resorption or damage to tooth 37. Of particular note is the presence of two small loculations at the lingual aspect of the cystic lesion, at the lingual cortical plate. These loculations suggests that the entity may indeed be multilocular, or that the lesion has perforated through the lingual cortical plate in an unusual way. Therefore, the entity may represent a benign odontogenic cyst, such as a residual cyst, or may represent a multilocular benign odontogenic tumor. A biopsy is recommended to confirm the diagnosis.
2. Additional views of lingual cortical defects in posterior third quadrant
These additional images of the cystic lesion at site 38 demonstrate the multilocular appearances of the dehiscences in the lingual cortical plate at site 38.
Orthogonal measurements of cystic lesion in posterior third quadrant
These orthogonal cross-sectional images demonstrate the dimensions of the expansile cystic lesion in the posterior third quadrant from various perspectives.
3. Secondarily affected tooth 37D
The cystic lesion at site 38 extends to the distal surface of the coronal two thirds of the distal root of tooth 37, and has caused a loss of lamina dura in this region. Tooth 37 likely remains vital.
4. Left palatine tonsillolith
A tonsillolith is present in the left palatine tonsil. This is an incidental finding with no clinical significance because tonsilloliths exfoliate spontaneously.
