Peripheral Ossifying Fibroma of the Posterior Maxilla: A Rare Case Report

Arriving at a correct diagnosis of lesions with the similar clinical presentation is a tricky business. Localized gingival overgrowths, one of the most common encountered lesions in the oral cavity, has to be studied carefully to differentiate between pyogenic granuloma, irritation fibroma, peripheral central giant cell granuloma, and peripheral ossifying fibroma (POF). POF is a reactive lesion of the oral cavity which has been described under various names like cement-ossifying fibroma (OF), peripheral cemental OF, occurs in about 9% of all gingival growths, usually seen in anterior maxilla followed by anterior mandible and is more prevalent in females. Etiological factors include chronic irritation or trauma due to faulty restorations, ill-fitting dentures and calculus. This is a case presentation of POF seen in the posterior maxilla of a 13-year-old female patient. Surgical excision followed by histopathological confirmation was done to arrive at the diagnosis.
