1. Fibrous dysplasia in left anterior maxilla
A well-defined, non-corticated area of granular bone formation is present within the left anterior maxilla, palatal and apical to sites 21 and 22. The contiguous palatal cortical plate and floor of the left nasal fossa has been replaced by this granular bone pattern. Mild palatal expansion is evident. This appearance is consistent with a localized zone of fibrous dysplasia. No treatment or biopsy is required.
Axial views of anterior maxilla
These axial cross-sectional images demonstrate a blending periphery between the area of granular bone formation in the left anterior maxilla and the contiguous trabecular bone. Note the mild palatal expansion associated with this area of granular bone. The incisive canal appears to be compressed by this area of fibrous dysplasia.
Coronal views of anterior maxilla
These coronal cross-sectional images demonstrate extension of the area of granular bone formation to the maxillary midline.
Mesiodistal views of anterior 2nd quadrant
These mesiodistal cross-sectional images demonstrate a granular appearance of the nasal floor and hard palate adjacent to the area of dysplastic bone formation in the left anterior maxilla.
Buccolingual views of anterior 2nd quadrant
These buccolingual cross-sectional images demonstrate mild palatal expansion associated with the area of fibrous dysplasia in the left anterior maxilla. The buccal cortex is unaffected.
Periodontal bone loss
Mild horizontal periodontal bone loss is present on teeth 14, 13, 24, and 25.
2. Buccal abrasion on tooth 14
The buccal surface of tooth 14 exhibits abrasion at the level of the cementoenamel junction.
