Histopathological characteristics of eruption mesenchymal calcified hamartoma: two case reports.

Odontogenic calcified masses were present in the opercula of lower first molars that were delayed in eruption. The masses were relatively small, opaque, white in color with a smooth texture. Histopathological examinations revealed that they contained osteodentin, cementum, and pulp-like components; however, not odontogenic epithelial cells or enameloid.
