1. Segmental odontomaxillary dysplasia in right posterior maxilla
The alveolar bone in the right posterior maxilla exhibits a high density appearance. The trabeculae are thickened and demonstrate a relatively vertical alignment. The maxillary alveolar process is enlarged buccolingually, and the maxillary sinus has failed to pneumatize the alveolar process. Teeth 54 and 55 are retained, and teeth 14 and 15 are congenitally absent. Tooth 17 is impacted, and no evidence of development of tooth 18 is present.
These radiographic findings are consistent with segmental odontomaxillary dysplasia, which is a developmental anomaly. No treatment is required.
Orthogonal views of right posterior maxilla
These orthogonal cross-sectional images demonstrate the high density appearance of the trabecular bone in the right posterior maxilla, as well as the vertical orientation of the trabeculae.
Axial views of maxilla
These axial cross-sectional images demonstrate relative buccolingual enlargement of the right posterior maxilla compared to the contralateral side. Note the absence of pneumatization within the right maxillary alveolar process.
Coronal views of maxilla
These coronal cross-sectional images demonstrate relative hypoplasia of the right maxillary sinus due to failed pneumatization of alveolar process. Note the relatively thickened right palatal gingiva compared to the contralateral side.
Mesiodistal views of right posterior maxilla
These mesiodistal cross-sectional images demonstrate retention of teeth 54 and 55, and congenital absence of teeth 14 and 15. Tooth 17 is impacted, and tooth 18 has failed to develop. Furcal bone loss is present on teeth 54 and 55, and the long-term prognosis of these teeth is poor.
Developing tooth 48
A small portion of the crown of the developing tooth 48 is captured in this imaging volume. No further radiographic assessment on the status of tooth 48 can be made based on this scan.
Developing teeth 28 and 38
Tooth 28 is developing in a vertical orientation relative to tooth 27. A small amount of the crown of tooth 38 is visible. No pathology is evident based on this imaging volume.
