Cemento-Ossifying fibroma (3rd stage)


  • Apices of several lower incisors.
  • Middle aged adults (typically black women).
  • Round, monolocular, often multiple.
  • Adjacent teeth: typically vital, not displaced, not resorbed. The periapical ligament space is intact.
  • Small, up to 1 cm in diameter.


  • Early stage: Radiolucent, not corticated.
  • Intermediate stage: Radiopacity within the apical radiolucencies.
  • Late stage: Densely radiopaque but surrounded by a thin radiolucent line.
