1. Rarefying osteitis at tooth 16MB: possible root fracture
The mesiobuccal root of tooth 16 exhibits rarefying osteitis around its entire circumference. No bone overlies the buccal surface of the root of the tooth. The possibility of the presence of a vertical fracture in the mesiobuccal root should be considered. The distobuccal root appears to have been secondarily infected. The palatal root of the tooth appears normal.
Clear right maxillary sinus
The right maxillary sinus is clear. There are no impediments to a potential right maxillary sinus lift.
2. Ectopic bone formation in dorsum of nose
Localized ectopic bone formation is present in the dorsum of the nose in the region overlying the septal cartilage. This has produced a slightly unusual nasal profile.
3. Persistent cleft at site 22
A persistent cleft is present in the maxillary alveolar process at site 22. Teeth 21 and 23 are convergent in this region. Tooth 22 is absent.
Axial views of anterior maxilla
These axial cross-sectional images demonstrate the cleft that is present at site 22, as well as the defect that is present at the nasal floor in this region. Note the convergence of teeth 21 and 23 in the region of the cleft.
Mesiodistal views of anterior second quadrant
These mesiodistal cross-sectional images demonstrate the prominent zone of bone deficiency at the nasal floor at site 22. The absence of any mesiodistal space between teeth 21 and 23 is evident in these images.
4. Mild cervical degenerative joint disease
Small osteophytes and mild subchondral sclerosis are present in the articular regions of the atlas and dens of the cervical vertebrae. This is a common incidental finding with no clinical significance that is suggestive of mild cervical degenerative joint disease.
5. Physiologic intracranial calcification
A midline physiologic calcification is present intracranially. This is an incidental finding with no significance.
6. Elongated styloid processes
The styloid processes are slightly elongated bilaterally. This is an incidental finding with no significance.
