Normal left and right TMJs in mandibular closed position

In the mandibular closed position, the left and right condylar heads are centrally positioned in their glenoid fossae. This is normal. No signs of osseous degeneration are present. It should be noted that the articular discs cannot be directly assessed in CBCT imaging. If visualization of the soft tissues of the joint is deemed necessary, an MRI can be ordered by the patient's physician.

Normal right TMJ in mandibular open position

In the mandibular open position, the right condylar head is positioned at the crest of the articular eminence. This is normal.

Posteriorly positioned left condylar head in mandibular open position

In the mandibular open position, the left condylar head is positioned slightly posteriorly to the crest of the articular eminence. If the articular disc is anteriorly displaced in the closed position, the disc is likely non-reducing in the open position.

Slightly microdont tooth 38

The developing tooth 38 demonstrates a slightly microdont crown morphology. This tooth appears normal otherwise, and root development has just begun. The left inferior alveolar nerve canal passes immediately apical to its developing root apex.

Slightly microdont tooth 48

The developing tooth 48 demonstrates a slightly microdont crown morphology. This tooth appears otherwise normal, and root development has just begun. The right inferior alveolar nerve canal courses immediately apical to the developing root apex of this tooth.

Slight vertical asymmetry in mandible

A slight vertical asymmetry is present in the mandible, with the right side demonstrating a greater vertical dimension than the left side. As a result, the occlusal plane appears canted towards the left side.

1. Concha bullosa

The left middle nasal concha contains air. This represents a concha bullosa and is an incidental finding with no clinical significance. The nasal cavity appears normal otherwise.

2. Sphenoid sinus mucositis

Mild mucositis is present in the sphenoid sinus. This is a non-significant incidental finding.

3. Physiologic intracranial calcification

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

4. Dystrophic calcification

A dystrophic calcification is present in the subcutaneous tissues overlying the region of the left mandibular angle. This is a non-significant incidental finding.

5. Enlarged jugular foramen

The left jugular foramen appears slightly enlarged as compared with the contralateral side. This is a variant of normal anatomy and a non-significant incidental finding.
