1. Periapical osseous dysplasia in association with teeth 32-43
There is a large collection of amorphous radiopacities with an attenuation comparable to dentin or bone located periapical to teeth 32, 31, 41, 42, and 43. These radiopacities are surrounded by a radiolucent lining of variable width. The buccal and lingual surfaces of the mandible adjacent to this region appear irregularly expanded. The contiguous buccal and lingual cortical plates appear thinned, but appear intact. The imaged dentition also exhibit excessive cementum formation, which is consistent with hypercementosis. This is commonly associated with periapical osseous dysplasia. Although periapical osseous dysplasia does not require treatment, continued radiographic monitoring is advised to assess its propensity for further growth.
2. Periapical osseous dysplasia associated with tooth 34
There is another region of amorphous bone located periapical to tooth 34, which appears to be surrounded by a radiolucent lining of variable width. This represents another focus of periapical osseous dysplasia. Depending on how many other sites of osseous dysplasia are present in the jaws, this may signify the presence of florid osseous dysplasia. Nonetheless, no treatment is necessary.
Axial views of the anterior mandible
These axial cross-sectional images demonstrate the presence of a large collection of amorphous, globular bone in the anterior mandible, located periapical to teeth 32, 31, 41, 42, and 43. Note the irregular expansion of the buccal and lingual surfaces of the mandible in this region. Another focus of osseous dysplasia is evident periapical to tooth 34. Note the presence of hypercementosis involving the roots of the imaged dentition.
Buccolingual views of the anterior mandible
These buccolingual cross-sectional images demonstrate that the buccal and lingual cortical plates of the anterior mandible appear significantly thinned, but appear to be intact.
Mesiodistal views of the anterior mandible
These mesiodistal cross-sectional images demonstrate that these amorphous radiopacities demonstrate a density comparable to dentin or bone, and are surrounded by a radiolucent lining of variable width.
