PDF: Florid cement-osseous dysplasia of maxilla and mandible: a rare clinical case

Cemento-osseous dysplasia is a group of disorders known to originate from periodontal ligament tissues.

The term florid cement-osseous dysplasia (FLCOD) was first proposed by Melrose et al in 1976 to describe a condition of exuberant multi quadrant masses of cementum and/or bone in both the jaws and in some cases, simple bone cavity like lesions in affected quadrant.

This condition has been interpreted as a dysplastic lesion or developmental anomaly arising in tooth bearing areas. The word 'florid' was introduced to describe the widespread, extensive manifestations of the disease in the jaws.

The World Health Organization (WHO) workshop group on head and neck tumors classified osseous dysplasia into four subtypes based upon the extent and radiographic appearances - Periapical osseous dysplasia in the anterior mandible.

Focal osseous dysplasia or Focal cemento-osseous dysplasia (FCOD) in a posterior region of the jaws, Florid osseous dysplasia (FOD) involving many quadrants of the jaws, and Familial gigantiform cementoma.
