Impacted + malformed tooth 15

Tooth 15 is distoangularly impacted and its crown and roots appear malformed. The crown of tooth 15 is located just inferior to the floor of the maxillary sinus apical to site 15. The root apex of tooth 15 is located at the junction of the anterior floor of the maxillary sinus and the lateral wall of the nasal fossa, just apical to the root apex of tooth 14. The periodontal ligament space is not completely visualized around the root circumference of this impacted tooth, which suggests the possibility of ankylosis. This tooth does not appear to be surrounded by a follicle space. The abnormal positioning and morphology of this tooth may be related to the reported history of trauma and facial surgery.

Impacted + malformed tooth 17

Tooth 17 is impacted and located within the inferior aspect of the right maxillary sinus, but surrounded by a thin shell of bone. This tooth is horizontally oriented with its crown facing distally, and its roots facing mesially. The crown and roots of tooth 17 appear severely malformed. The crown of tooth 17 is fused with the crown of the impacted tooth 18, and the distal root of tooth 17 is fused with the crown of the impacted tooth 15. This tooth does not appear to be surrounded by a follicle space. The abnormal positioning and morphology of this tooth may be related to the reported history of trauma and facial surgery.

Impacted tooth + malformed tooth 18

Tooth 18 is impacted with a mesioangular orientation, and located within the posterolateral aspect of the right maxillary sinus. A thin shell of bone surrounds this impacted tooth. The crown of tooth 18 appears malformed. The crown of tooth 18 is fused to the crown of the impacted tooth 17, and the root apices of tooth 18 are embedded within the posterolateral wall of the right maxilla. The crown of this tooth does not appear to be surrounded by a follicle space. The abnormal positioning and morphology of this tooth may be related to the reported history of trauma and facial surgery.

Axial views of the right maxillary sinus

These axial cross-sectional images demonstrate that tooth 15 is located within the anterior and inferior aspect of the right maxillary sinus, tooth 17 is located within the central aspect of the right maxillary sinus, and tooth 18 is located within the posterolateral aspect of the right maxillary sinus. The inferior aspect of tooth 15 is attached to the maxillary alveolar process and the root apices of tooth 18 are attached to the posterolateral of the right maxilla. Tooth 17 is suspended within the body of the right maxilla through its attachments to teeth 15 and 18.

Sagittal views of the right maxillary sinus

These sagittal cross-sectional images demonstrate how the crowns of teeth 18 and 17 are fused, and how the distal root of tooth 17 is fused with the crown of tooth 15. Tooth 15 is located anterior and inferior to tooth 17, and tooth 17 is located anterior and inferior to tooth 18.

Mesially tilted tooth 16

Tooth 16 appears normal radiographically, and is not within close proximity to the impacted teeth 15, 17, and 18. The crown of tooth 16 appears mesially tilted into site 15.

Normal tooth 14

Tooth 14 appears normal radiographically. There is no evidence of displacement or root resorption in association with its close proximity to the impacted tooth 15. The root apex of tooth 15 is located apical to the root apex of tooth 14.

Developing teeth 28, 38, 48: probable impaction of teeth 38 and 48

Teeth 28, 38, and 48 are developing normally. Teeth 38 and 48 are partially captured in this imaging volume, and demonstrate a mesioangular orientation, suggesting the potential for future impaction. The respective relationships of the left and right inferior alveolar nerve canals relative to teeth 38 and 48 are not captured in this imaging volume.

1. Adenoid hyperplasia

The pharyngeal tonsils are enlarged, which is an appearance consistent with adenoid hyperplasia. In an adolescent patient, this represents an incidental finding with no clinical significance.

2. Mild mucositis of left maxillary sinus

The left maxillary sinus exhibits mild mucositis, which represents an incidental finding with no clinical significance.

3. Concha bullosa

The right 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.

4. Right palatine tonsillolith

A tonsillolith is present in the right palatine tonsil. This is an incidental finding with no significance because tonsilloliths exfoliate spontaneously.

5. Physiologic intracranial calcification

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

6. Cerumen in external ear canal

Cerumen (earwax) is visible in the left and right external ear canals. This is a non-significant incidental finding.

7. Calcified stylohyoid ligaments

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