Mixed-Radiopaque Non-Odontogenic Lesions Flashcards
What is cemento-osseous dysplasia? Characteristics?
What are the 3 types of Cemento-Osseous Dysplasia?
A benign self-limiting growth disturbance of bone, not a neoplasm.
- Not a neoplams
- Do not cause enlargement.
- Dont need to be removed.
- Focal: Solitary lesion, most common
- Periapical: Multiple lesions usually in anterior mandible.
- Florid: Multiple, bilateral lesions throughout jaw.
What are the characteristics of periapical cemento-osseous dysplasia?
- Most commonly multiple periapical lesions on mandibular anterior teeth.
- More common in African Americans
- Progressive mineralized product that can look RL, M, or RO.
What are the characteristics of Focal Cemento-Osseous dysplasia?
- Occurs only in one location.
- Usually posterior mandible
- more common in Caucasians.
- Can be RL, M, or RO
What are the characteristics of Florid Cemento-osseous dysplasia?
- Occurs in 2+ quadrants only
- More common in african americans
- Multiple M lesions.
What is fibrous dysplasia? how does the severity of disease change? Characteristics?
- 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!
What are the characteristics of monostotic fibrous dysplasia?
-Involves only one bone.
What are the characteristics of polyostotic fibrous dysplasia? Types?
Involves multiple bones, begins early in life, systemic features and very rare.
- Jaffe Syndrome: Involves fewer bones, cafe-au-lait melanotic macules.
- McCune-Albright syndrome: Involves most of skeleton, endocrine abnomralities, cafe-au-lait macules.
Treatment of fibrous dysplasia?
- Bony recontouring after lesion stops growing.
- NO radiation because it can cause it to become malignant.
What is central ossifying (calcifying) fibroma? Characteristics?
True neoplasm of bone with persistent and progressive growth.
- Grows slowly
- Can cause bony expansion and displacement of teeth.
What are the radiographic features of central ossifying(calcifying) Fibroma? Treatment?
- Well demarcated
- May appear radiolucent, RL with foci of RO areas, Radiopaque.
Treatment: Enucleation or curettage, Low recurrence rate.
What is idopathic osteosclerosis?
Focal area of dense bone of unknown cause.
What is an osteoma? radiographic? Can be located where? Treatment?
Benign tumor of bone.
-Well defined, radiopaque, slowly growing.
Periosteal=surface of bone
Endosteal=inside bone.
Observation or removal if symptomatic/deforming.
What is mucositis? Radiographic? Treatment?
Inflammation of lining of a sinus due to trauma, allergy, irritation.
-Well-defined, non-corticated, radiopaque band of increased radiopacity paralleling the sinus wall.
Treatment: None
What is sinusitis? Treatment?
Inflammation of lining of sinuses due to allergen, infection.
Treatment: Control infection, relieve pain, or surgery.
What is a mucous retention pseudocyst? Radiographic? Treatment”?
Blockage of seromucous glands in sinus.
-Well defined, non-corticated, smooth, dome-shaped, radiopaque mass.
Treatment? None
