Ameloblastic fibro-odontoma

Odontogenic myxoma

  • It represents approximately 3 - 6% of all odontogenic tumors. It is painless and grows slowly.
  • It can occur at any age but most commonly in the second and third decades of life.
  • More often affects the mandible (molar/premolar region).
  • Typically multilocular. The internal septa are thin and straight forming a tennis racket or honeycomb appearance.
  • Usually has well defined borders.
  • Adjacent teeth can be displaced but rarely resorbed. It causes less bone expansion than in other benign tumors.
