Florid Cement-Osseous Dysplasia (Report of Two Cases)

Florid cement-osseous dysplasia (FLCOD) of the jaws is a multifocal dysplastic lesion of the bone trending toward mineralization and opacity. It is a member of a group of disorders originating from periodontal ligament tissue. This lesion is limited to the jaws and patients do not develop any evidence of bone disease in other parts of the skeleton. A majority of the lesions are asymptomatic and discovered in usual radiographs to be radiolucent or opaque. Incorrect diagnosis of the lesion leads to unnecessary root canal therapy in radiolucent stage and osteomyelitis after tooth extraction in opaque stage.

Two cases of florid cermento-osseos dysplasia are reported in this article. One case had been referred because of tooth mobility consequent to periodontal disease as well as for routine dental treatment and the other case referred with bone expansion.

Because of rarity of expansion as a symptom in this disease, it is accidentally observed in usual radiographs in different developmental stages. For avoiding of unnecessary or harmful treatments, recognition of this lesion is necessary for all dentists.
