2. Early degenerative joint disease in the left TMJ

In the mandibular closed position, the left condylar head is slightly superiorly positioned in the glenoid fossae, and the joint spaces reduced. Small erosions are present on the articular surfaces of the joint, and subchondral sclerosis is visible. This is suggestive of the presence of mild degenerative joint disease in the left temporomandibular joint.

1. Anteriorly displaced articular disc and remodeling in right TMJ

In the mandibular closed position, the right condylar head is posteriorly positioned in the glenoid fossa. This is suggestive of the presence of an anteriorly displaced articular disc. The condylar head exhibits a reduced anterior-posterior dimension, which is indicative of joint remodeling in its current posterior position within the glenoid fossa. The temporal component of the joint does not exhibit any signs of degeneration.

3. Fixation screw in posterior left mandible abuts left inferior alveolar nerve

A fixation screw in the posterior left mandible abuts the superior cortex of the left inferior alveolar nerve canal and extends through the mandibular alveolar process to abut the lingual cortical plate. The remainder of the fixation screws in the left mandible appear normal radiographically.

4. Fixation screw impinges upon right mandibular nerve canal

A fixation screw in the right posterior mandible impinges upon the right inferior alveolar nerve canal and extends through the mandibular alveolar process to extend through the lingual cortical plate. This impinging fixation screw may be the source of the patient's symptoms. The remaining fixation screws in the right mandible appear normal radiographically.

5. Caries on tooth 27D

A small carious lesion is present on the distal aspect of tooth 27, at the level of the cementonenamel junction.

6. Caries on tooth 45D

A carious lesion is present on the distal aspect of the crown of tooth 45. This lesion does not involve the pulp system of the tooth.

Generalized widening of PDL spaces: orthodontic treatment

There is a relatively uniform widening of the periodontal ligament space around the roots of the imaged dentition. This is likely secondary to concurrent orthodontic therapy.

7. Mucous retention cyst + mild mucositis in right maxillary sinus

A mucous retention cyst and mild mucositis are present within the right maxillary sinus. This represents a non-significant incidental finding.

8. Physiologic intracranial calcification

A midline physiologic calcification is present intracranially. This is an incidental finding with no significance.

9. Calcified stylohyoid ligaments

The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.

10. Right palatine tonsilloliths

Tonsilloliths are present in the right palatine tonsil. This is an incidental finding with no clinical significance because tonsilloliths exfoliate spontaneously.

11. 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.

12. Calcified cornua of thyroid cartilages

The left and right horns of the thyroid cartilage are partially calcified. This is an incidental finding with no clinical significance.
