Findings:

The UR8-6 region has severe loss in vertical alveolar ridge height. The UR5 has widening of the apical periodontal ligament space with evidence of apical pathology. This could be a fibrous scar, an apical granuloma or radicular cyst secondary to chronic apical periodontitis. 

The LL7-6 region has moderate loss in vertical alveolar ridge height. 

The LR7 region has moderate loss in vertical alveolar ridge height. 

Severe periodontal disease is affecting the lower anterior teeth, UL6 and UL7 with loss of attachment of the latter.

The right maxillary sinus has severe mucosal thickening with erosion of the sinus cortical floor and part of the alveolar ridge in the UR6 region. ENT referral is suggested to rule out malignancy. 

Both TMJs have severe degenerative joint disease with condylar osteophytes and flattening of the right glenoid fossa. The left condylar head has an Ely’s cyst (also called a subcortical or subchondral cyst).
