Cementifying fibroma and ossifying fibroma are classified together under cemento-ossifying fibroma and defined as osteogenic tumors according to the WHO histological classification in 1992. Cemento-ossifying fibroma is a relatively rare tumor, generally occurring in adult jaw bones. Few reports have described cementoossifying fibroma occurring in many places in the same jaw bone. This report describes a rare case of cementoossifying fibroma arising symmetrically in both mandibular molar regions. The patient was a 15-year-old girl, in whom tumors were detected bilaterally in the mandibular molar region at a dental clinic. Histological examination showed a basophilic calcified mass and a stroma consisting of cellular fibrous tissue. The histopathological diagnosis was cemento-ossifying fibroma.
