1. Healed extraction socket at site 46
The extraction socket at site 46 has healed normally, and has a density that is similar to that of the adjacent trabecular bone. The buccolingual width of the crestal bone is narrow.
2. Widened PDL space of tooth 46D
The periapical periodontal ligament space of the distal root of tooth 46 is slightly widened. This may represent a persistent low-grade endodontic lesion, or a healing post-treatment appearance. The obturation in the mesial root of the tooth is laterally positioned, which is suggestive of an unobturated lingual canal in the mesial root. However, the mesial root does not exhibit significant periapical pathology.
3. Mild mucositis of left maxillary sinus
The left maxillary sinus exhibits mild mucositis, which represents an incidental finding with no clinical significance.
4. Possible ectopic bone formation in the right maxillary sinus
A well-defined unilocular entity with a calcified periphery is present within the posterior region of the right maxillary sinus in the region apical to tooth 17. The calcified structure appears to resemble bone, which suggests that this may represent a region of ectopic bone formation. This entity is embedded within the thickened mucosal lining of the right maxillary sinus, and has not had any effect on the surrounding structures. In the absence of any symptoms, this is a non-significant incidental finding.
Axial views of posterior left maxilla
These axial cross sectional images demonstrate the sclerotic periphery of the unilocular void entity that is embedded within the thickened mucosal lining of the right maxillary sinus. Internally, granular calcification appears to be present, which has a density that is similar to that of the adjacent trabecular bone. Note the absence of any effects upon the surrounding structures.
Sagittal views of right maxillary sinus
These sagittal cross sectional images demonstrate the separation of the ovoid calcified entity from the underlying bone by a thin zone of mucosa. The entity is not continuous with sinus walls or floor.
Coronal views of posterior right maxilla
These coronal cross sectional images demonstrate the absence of any effect of the calcified ovoid entity upon the adjacent structures in the right maxillary sinus.
5. Calcified stylohyoid ligaments
The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.
6. Mild cervical degenerative joint disease
Small osteophytes, a small joint mouse 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.
