Dentinogenesis imperfecta

The crowns of the maxillary and mandibular dentition appear bulbous and exhibit a prominent constriction in their cervical regions. The pulp chambers of these teeth appear obliterated. The enamel lining many of these teeth appear to have abraded off, and the dentin exposed. The crowns of teeth 17, 13, 12, 11, 35, 32, 31, 41, 42, 43, 44, and 45 appear partially or entirely absent. Periapical rarefying osteitis is evident involving the retained roots of teeth 12 and 11. The internal trabecular architecture in the maxilla and mandible demonstrate a normal density and organization, which suggests that concurrent osteogenesis imperfecta is likely not present.

Clear left maxillary sinus

These sagittal cross-sectional images demonstrate that the left maxillary sinus is clear and free of pathology.

1. Transverse ridge apical to site 27

A shallow transverse ridge is present along the floor of the maxillary sinus apical to site 27, which may slightly impede a sinus lift procedure in this region.

Clear right maxillary sinus

These sagittal cross-sectional images demonstrate that the right maxillary sinus is clear and free of pathology.

2. Transverse ridge apical to site 18

A shallow transverse ridge is present along the floor of the maxillary sinus apical to site 18, which may slightly impede a sinus lift procedure in this region.

Axial views of the maxillae

These axial cross-sectional images demonstrate the normal appearance of the bone pattern in the maxillae. The buccal and palatal cortical plates appear normal and intact. The walls of the maxillary sinuses are intact, and demonstrate a normal contour and thickness.

Axial views of the mandible

These axial cross-sectional images demonstrate the normal appearance of the internal trabecular architecture in the mandible. The contiguous buccal and lingual cortical plates are intact and exhibit a normal thickness.
