We present a rare case of mandibular PCOD in a woman of 55 years, who presented with moderate swelling and mobility of teeth 32-33-34. Endoral radiography showed that these teeth had been devitalized; they had deep periodontal pockets and marked radicular radiotransparency; the root apices exhibited mixed radiotransparency and radio-opacity. Clinical and radiographical findings led to a diagnosis of periapical rarefying osteitis, and the three teeth were thus extracted. Due to the persistence of swelling and slight pain post-extraction, a cone-beam computed tomographic scan was taken; this showed a mixed radiotransparent and radio-opaque lesion in the area of the extracted teeth. A bone biopsy of the affected area was taken for histopathological evaluation; a diagnosis of PCOD was rendered. This case demonstrates the importance of a full investigation when a patient presents after tooth extraction with non-healing socket, pain, and swelling. A multidisciplinary approach is required to manage these rare cases. ER -
