Q

What is cemento-osseous dysplasia? Characteristics?

What are the 3 types of Cemento-Osseous Dysplasia?

A

A benign self-limiting growth disturbance of bone, not a neoplasm.

  • Not a neoplams
  • Do not cause enlargement.
  • Dont need to be removed.
  1. Focal: Solitary lesion, most common
  2. Periapical: Multiple lesions usually in anterior mandible.
  3. Florid: Multiple, bilateral lesions throughout jaw.

Q

What is fibrous dysplasia? how does the severity of disease change? Characteristics?

A
  • Non-neoplastic developmental disturbance of bone growth.
  • Earlier the gene mutations occurs, the more severe the disease is.
  • Slowly growing, poorly defined, RO, blends into surrounding bone.
  • bony expansion
  • Ground glass appearance on radiograph
  • ONLY in 20 years or younger patients!

Q

What are the characteristics of polyostotic fibrous dysplasia? Types?

A

Involves multiple bones, begins early in life, systemic features and very rare.

  1. Jaffe Syndrome: Involves fewer bones, cafe-au-lait melanotic macules.
  2. McCune-Albright syndrome: Involves most of skeleton, endocrine abnomralities, cafe-au-lait macules.

Q

What is an osteoma? radiographic? Can be located where? Treatment?

A

Benign tumor of bone.
-Well defined, radiopaque, slowly growing.
Periosteal=surface of bone
Endosteal=inside bone.

Observation or removal if symptomatic/deforming.
