1. Mature cemental dysplasia between teeth 42 and 43

A large mature focus of cemental dysplasia is present between the roots of teeth 42 and 43. Internally, this entity is composed of an amorphous radiopaque mass. The periphery of the entity is comprised of low density granular bone. The lesion has caused mild buccolingual expansion of the alveolar process, as well as a small amount of root displacement of teeth 42 and 43. Although this is not a common presentation for cemental dysplasia, it is not unheard of. The diagnosis is supported by the presence of other foci of cemental dysplasia throughout the mandible. No root resorption or damage has occurred to teeth 42 and 43. Cemental dysplasia is a region of increased bone activity, which would correspond to a hot spot in a technetium bone scan.

2. Immature cemental dysplasia at tooth 33

An immature focus of periapical cemental dysplasia is present at tooth 33. This entity is composed of low-density granular bone with a sclerotic periphery. The root of tooth 33 has not been affected. No treatment is required. This region exhibits active bone turnover and would correspond to a hot spot on a technetium bone scan.

3. Immature cemental dysplasia at tooth 34

An immature focus of cemental dysplasia is present in the periapical region of tooth 34. This entity is comprised of low-density granular bone with a sclerotic periphery. Increased activity would likely be seen in this region in a technetium bone scan.

Florid osseous dysplasia

The presence of multiple foci of cemental dysplasia throughout the mandible is indicative of the presence of Florid osseous dysplasia. No treatment is required.

4. Partially mature cemental dysplasia in periapical region of tooth 36

A partially mature focus of cemental dysplasia comprised of a heterogeneous zone of granular bone with a sclerotic periphery is present in the periapical region of tooth 36. The roots of the tooth have not been affected. This region of increased bone turnover would correspond to a hot spot on a technetium bone scan.

Axial views of mandible

These axial cross-sectional images demonstrate the large focus of cemental dysplasia in the interradicular regions of teeth 42 and 43. Note the buccal expansion of the alveolar process by the entity, and the mild splaying of the roots of teeth 42 and 43. Although this is an uncommon radiographic appearance for cemental dysplasia, it is still consistent with the diagnosis.
