FLORID CEMENTO-OSSEOUS DYSPLASIA - RADIOGRAPHIC STUDY WITH SPECIAL EMPHASIS ON COMPUTED-TOMOGRAPHY

This article describes the computed tomographic and conventional radio graphic findings for florid cemento-osseous dysplasia. A low-density t hin layer or cystlike area was observed around the high-density masses in the tooth-bearing area in the seven cases studied. Expansion of th e buccal and lingual cortical plates was observed in association with cystlike areas, but was infrequently observed in florid cemento-osseou s dysplasia not having such areas. The computed tomographic number of the high-density masses ranged from 772 to 1587 Hounsfield Units and w as equivalent to that of cementum or cortical bone.
