Bone pathology I - fibro-osseous lesion (Cemento-osseous dysplasia) Flashcards
Name the cemeto-osseous dysplasia and what they affect?
1) focal cemento-osseous dysplasia
- 1 tooth anterior region
2) periapical cemental dysplasia
- multiple teeth, mosty anterior teeth
3) florid cemento-osseous
- whole jaw or whole quadrant of jaw
what is cemento-osseous dysplasia?
fibrous tissue with varying amounts of cementum
cementum-like calcified tissue in the fibrous tissue
focal osseous dysplasia?
single periaplical lesion
periapical osseous dysplasia?
multiple small periapical lesions
florid osseous dysplasia?
multiple large lesions involving one or more quadrants in one or both jaws
who is more likely to get cemento-osseous dysplasia?
prevalent in woman
majority of pts over 30
mandible or maxilla
mandible
radiographic appearance (general)?
ranges from radiolucent to mottled radiopaque
what can you see here?
fibrous material with calcified material
looks like cellular cementum (right image)
radiographic appearance of periapical cemental dysplasia?
location:
root apices
rarely over the apical third
mandibular anterior teeth
multiple or bilateral
periapical cemental dysplasia change overtime?
early stage = radiolucent
later stage = become mixed
even later = more radiopaque
differential diagnosis?
periapical radicular cyst
periapical granuloma
periapical abscess
What does this show?
periapical cemental dysplasia
radiographic appearance of florid osseous dysplasia?
location:
bilateral in both jaws
mandible is more commonly affected if only one jaw involved
what is shown?
florid osseous dysplasia
differential diagnosis?
odontogenic keratocyst
many odontogenic tumours
