1. Abrasion on tooth 21MB
A well-defined defect is present along the mesiobuccal aspect of the crown of tooth 21, at the level of the cemento-enamel junction. Although this likely represents an atypical focus of abrasion, clinical correlation is recommended to rule out the possibility of caries or root resorption.
2. Sclerotic bone pattern at site 36
A sclerotic bone pattern is present within the alveolar process of the edentulous site 36. This likely reflects a history of inflammatory disease in association with the extracted tooth 36, and represents a non-significant incidental finding.
3. Abrasion on tooth 34B
Abrasion is present along the buccal surface of tooth 34, at the level of the cemento-enamel junction. This abrasion appears to be filled with a radiolucent restoration, but clinical correlation is necessary to confirm this.
4. Abrasions on teeth 45L, 46L
Abrasions are present along the lingual surfaces of teeth 45 and 46, at the levels of their cemento-enamel junctions.
Generalized periodontal bone loss
There is generalized mild to moderate horizontal bone loss involving the imaged dentition.Severe horizontal bone loss is present along the distal aspect of tooth 46.
5. Mild mucositis of both maxillary sinuses
Mild mucositis is present in both maxillary sinuses. This represents an incidental finding with no clinical significance.
Sagittal views of the left maxillary sinus
These sagittal cross-sectional images demonstrate the presence of mild mucositis in the left maxillary sinus, which should not impede a sinus lift procedure.
6. Transverse ridge apical to tooth 27
A transverse ridge is present along the floor of the maxillary sinus apical to tooth 27, which may slightly impede a sinus lift procedure in this region.
Sagittal views of the right maxillary sinus
These sagittal cross-sectional images demonstrate the presence of mild mucositis in the right maxillary sinus, which should not impede a sinus lift procedure.
7. Severe sinusitis in right sphenoid sinus
The right locule of the sphenoid sinus is nearly completely opacified, which suggests the presence of severe mucositis. A referral to an ENT specialist may be considered to substantiate this interpretation.
Sclerosis of the right sphenoid bone
The right side of the sphenoid bone demonstrates a dense, granular bone pattern, which appears to involve its lesser wing, body, greater wing, and pterygoid processes. The walls of the right sphenoid sinus appear thickened. There is presently no radiographic evidence of narrowing of the neuroforamina in the affected regions. This could represent fibrous dysplasia involving the right sphenoid bone, or could be secondary to the presence of chronic sinusitis.
Axial views of the sphenoid bone
These axial cross-sectional images demonstrate that that the right side of the sphenoid bone is comprised of dense, granular bone. A normal trabecular bone pattern is observed in the left side of the sphenoid bone. Note that the right foramen ovale and spinosum demonstrate a normal caliber as compared to the contralateral side. The right orbital fissures, sphenopalatine foramen, and greater palatine nerve canal also demonstrate a normal course and caliber.
Coronal views of the sphenoid bone
These coronal cross-sectional images demonstrate that the walls of the right locule of the sphenoid sinus are thickened, with the presence of severe mucositis. The right foramen rotundum and vidian canal demonstrate a normal course and caliber as compared to the contralateral side.
8. Pneumatization of the petrous temporal bones
Air is present within the bilateral petrous temporal bones, which extends to the petrous apices. These findings suggest pneumatization of the petrous temporal bones. This is a variant of normal anatomy, and a non-significant incidental finding.
9. Dystrophic calcifications in facial skin
Dystrophic calcifications are observed within the skin of the left and right face. This is a non-significant incidental finding.
10. 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.
11. Calcified stylohyoid ligaments
The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.
