Gemination of tooth 25

Gemination is evident in tooth 25, as the crown and root of this tooth have separated into distinct teeth located within the buccal and palatal aspects of the alveolar process. The crowns of these teeth are in contact with each other, but a thin radiolucent margin separates their enamel linings, which suggests that these crowns are not fused. Root development in these teeth appear 80% complete, and their developing root apices are located inferior to the floor of the maxillary sinus. There is no evidence of periapical or periradicular pathology involving these teeth.

Axial views of tooth 25

These axial cross-sectional images demonstrate that tooth 25 has geminated into distinct teeth located within the buccal and palatal aspects of the alveolar process. The crowns of these teeth appear to be in contact with each other, but their enamel linings do not appear to be fused. The periodontal ligament space lining the root circumferences of these geminated teeth appear thin and uniform, and their lamina dura intact.

Buccolingual views of tooth 25

These buccolingual cross-sectional images demonstrate the presence of two distinct teeth located within the buccal and palatal aspects of the alveolar process at site 25. The contiguous buccal and palatal cortical plates appear normal and intact.

Mesiodistal views of tooth 25

These mesiodistal cross-sectional images demonstrate the normal appearance of the periapical and periradicular bone surrounding the geminated teeth at site 25. There is no evidence of periapical or periradicular pathology involving these teeth.

Developing tooth 28

Tooth 28 is developing normally in the alveolar process, and root development has not yet begun. The follicle surrounding the crown of this tooth appears normal.
