Florid Cement Osseous Dysplasia and Chronic Diffuse Osteomyelitis in Maxilla

Chronic diffuse osteomyelitis is an intermodular bone infection which may be resulted from a localized osteitis, previous acute osteomyelitis or prior infective processes. Florid cement-osseous dysplasia brings about a change in perfusion and in case of infection will pave the way for osteomyelitis. Complaining of chronic pain and pus drainage, a patient referred to the center of oral diseases for removing the right maxillary first molar and was diagnosed with chronic diffuse osteomyelitis in florid cement-osseous dysplasia. Bone expansion of all four quadrants of the jaws, pain, pus drainage, sinus involvement made this patient unusual (abnormal).
