apex…ROOT TIP visible
Periapical Cemento-osseous Dysplasia can show variable radio findings DEPENDING on DURATION of the lesion: Earliest lesions are ________

CENTRAL opacification
Periapical Cemento-osseous Dysplasia can show variable radio findings DEPENDING on DURATION of the lesion: Late stage lesions are opaque with a __________
a thin lucent rim
Periapical Cemento-osseous Dysplasia can show variable radio findings DEPENDING on DURATION of the lesion: SCLEROTIC lesions can DO WHAT???
fuse to tooth roots
What is the treatment for Periapical Cemento-osseous Dysplasia? What treatment is contraindicated?
NO tx required…DO NOT RCT
What is a unique feature about the progression of a Periapical Cemento-osseous Dysplasia?
It can regress at any time!
What is the cemento-osseus dysplasia that presents as multiple posterior quadrants affected, can affect ant Md also?
FLORID Cemento-Osseus Dysplasia
What are the characteristic demographics for Florid Cemento-Osseous Dysplasia?
40-45 year old black females (once again)
Which two cemento-osseus dysplasias happen in middle aged black females?
periapical and florid (focal is the only one that does not)
Where does FLORID cemento-osseus dysplasia occur?
multiple posterior quads, but CAN affect mand ant
Florid Cemento-Osseous DysplasiaUsually is usually ______ and often discovered on routine radiographic study ________ of the bone is seen occasionally
painless…expansion
Radiographic findings of Florid Cemento-Osseous Dysplasia: Radiolucent to mixed radiolucent-radiopaque to predominantly ______, often with ______ borders
Rounded or ______ architecture
opaque…lucent…lobular
Radiographic findings of Florid Cemento-Osseous Dysplasia: Border varies from well-defined to _____ within individual lesions
HAZY
Interesting If Florid Cemento-Osseous Dysplasia lesions become infected, large portions of the bone may _______
sequestrate
Even though FOCAL cemento-osseus dysplasia does not affect ALL of the same “classic” demographics as florid or periapical, what is one factor that remains constant?
females still predominate, but age and race not the same
What are the 3 primary sites for FOCAL cemento-osseus dysplasia?
- mandibular BODY 2.PM/1st molar area 3. Edentulous areas
FOCAL cemento-ossifying dysplasia is usually painless and often discovered on routine radiographic study….Some clinical expansion is seen in as many as _____ of patients
1/3
Radiographic findings of focal cemento-ossifying dysplasia Radiolucent to mixed to _______Variable degrees of ________ are seen from primarily lucent lesions to primarily opaque lesions with all gradations inbetween….Rounded or ______ architecture
opaque…calcification…lobular
Radiographic findings of focal cemento-ossifying dysplasia …Generally remain ______ than in the florid form and are RARELY larger than ___
SMALLER….1.5cm
Radiographic findings of focal cemento-ossifying dysplasia: Border varies from well-defined to hazy Opaque lesions often with a lucent ____
HALO…i can see yo HALO
What is the typical treatment for a focal cemento-ossifying dysplasia?
no tx required
