A - Periapicalcemento-osseous dysplasia .
B. Focal cemento-osseous dysplasia .
C. Florid cemento-osseous dysplasia .
It is asymptomatic and discovered when radiographs are taken for other purposes .
Early lesions appear as circumscribed areas of radiolucency involving the periapical
Area of a tooth
So at this stage , it can not be differentiated from periapical granuloma or cyst.
With time ,adjacent lesions often fuse to form a linear pattern of radiolucency that envelopes the apices of several teeth .
The lesions tend to mature over times to create a mixed radiolucent and radiopaque appearance .
AT the end stage the lesions show a circumscribed radiopaque surrounded by a narrow radiolucent rim .
the third to sixth decades .
Lesions occur in dentulous and edentulous areas ,with many examples noted in extraction sites .
It appears with multifocal involvement
Not limited to the anterior mandible .
Although many cases demonestrate multifocal lesions only in the posterior portion of the jows .many patients also reveal involvement of the anterior mandible
It involves Black women .
radiolucent but ,with time become mixed ,
Then predominantly radiopaque with only a thin peripheral radiolucent rim .
On occasion , a lesion can become totally radiopaque and blend with the adjacent
noraml appearing bone
Both dentulous and edentulous areas are affected and the involvement appears to be unrelated to the presence or absence of teeth .
Is a mixture of woven bone , lamellar bone and cememtum –like particles .
As the lesions mature and become more sclerotic , the ratio of fibrous c . T to mineralized material decreases and the bone trabecule become more thicker and fuse to each other .
Management of the symptomatic patient is more difficult . At this stages , there is an inflammatory component to the disease and the process is typically a chronic Osteomyelitis involving dysplastic bone and cementum .
