Peripheral ossifying fibroma: Series of five cases.

Peripheral ossifying fibroma (POF) is a reactive lesion of the gingival tissues that predominantly affects women and is usually located in the maxilla anterior to the molars. It originates from the cells of the periodontal ligament. The definitive diagnosis is established by histological examination, which reveals the presence of cellular connective tissue with focal calcifications. Surgical excision is the treatment of choice, though the recurrence has been reported. We present a clinical, radiological and histological review of five cases of POF diagnosed and treated at our institute.
