1. Ameloblastic fibro-odontoma causing impaction of tooth 55

A small, irregularly shaped calcification is present occlusal to the crown of the impacted tooth 55. The follicle is also irregularly enlarged around this calcified material. The periodontal ligament space is visible around the root circumference of tooth 55, which suggests this tooth is not ankylosed. These radiographic findings are most suggestive of an ameloblastic fibro-odontoma, which is the probable cause of impaction of tooth 55. The crown of tooth 55 can be accessed from the buccal aspect of the alveolar process mesial to the coronal half of the roots of the unerupted tooth 16. No resorption has occurred to teeth 14 and 16.

Congenital absence of tooth 15

Tooth 15 is congenitally absent.

Axial views of tooth 55

These axial cross-sectional images demonstrate the visible periodontal ligament space surrounding the roots of the impacted tooth 55. This appearance suggests the cause of impaction of tooth 55 is not related to ankylosis.

Mesiodistal views of posterior 1st quadrant

These mesiodistal cross-sectional images demonstrate the presence of a well-defined calcification occlusal to tooth 55. This intrafollicular calcification suggests that the cause of impaction of tooth 55 is an ameloblastic fibro-odontoma. Note the normal appearance of the developing teeth 14 and 16. Tooth 15 is congenitally absent.

Buccolingual views of tooth 55

These buccolingual cross-sectional images demonstrate irregular enlargement of the follicle overlying the occlusal aspect of tooth 55. The crown of tooth 55 can be accessed from the buccal aspect of the alveolar process.

2. Opacified right maxillary sinus

The right maxillary sinus is opacified. This suggests the presence of acute sinusitis.
