Periapical Cemento-Osseous Dysplasia

This CT was performed for recurrent rhinosinusitis and incidentally demonstrated multiple periapical sclerotic lesions with surrounding lucencies and ground-glass attenuation associated with the maxillary and mandibular teeth. The findings are consistent with periapical cemento-osseous dysplasia otherwise known as florid cemont-osseous dysplasia. These are usually clinically silent lesions that occur most often in middle age african-american females which fit the demographic of this particular patient. They are non-neoplastic fibro-osseous lesions which do not require treatment when asymptomatic. There are reports of poor socket healing following tooth extraction and poor response to antibiotics when complicated by osteomyelitis.
