What is Benign Cementoblastoma?
Only true cemental-origin neoplasm. Proliferation of cellular cementum.
Who is typically affected by Benign Cementoblastoma?
Males more than females, around 25 years old.
What are the key clinical features of Benign Cementoblastoma?
Vital lower molar/premolar, slow growing, may be painful.
What are the radiographic features of Benign Cementoblastoma?
Well-defined radiopaque mass fused to root with radiolucent rim. May cause root resorption.
Describe the histological features of Benign Cementoblastoma.
Calcified cementum-like tissue, reversal lines, cementoblasts, fibrovacular stroma, active rim.
What are the differential diagnoses for Benign Cementoblastoma?
Odontoma (not fused), Osteoblastoma (aspirin responsive), Hypercementosis (no radiolucent rim), Focal sclerosing osteomyelitis (non-vital).
What is the treatment for Benign Cementoblastoma?
Excision with tooth removal.
What is Cemento-Ossifying Fibroma?
Well-demarcated neoplasm with fibrous tissue and bone/cementum calcifications.
What are the clinical features of Cemento-Ossifying Fibroma?
Females more than males (5:1), middle age, mandible more than maxilla, premolar-molar region, facial asymmetry.
Describe the radiographic stages of Cemento-Ossifying Fibroma.
Early: radiolucent; Later: mixed; Mature: radiopaque with rim.
What is seen histologically in Cemento-Ossifying Fibroma?
Collagenous fibrous stroma, metaplastic bone/cementum, well demarcated, sometimes encapsulated.
What are the differential diagnoses for Cemento-Ossifying Fibroma?
RL: Ameloblastoma, myxoma; RO: fibrous dysplasia, osteomyelitis.
What is the treatment approach for Cemento-Ossifying Fibroma?
Enucleation if small, surgical excision if large.
What is Periapical Cemental Dysplasia?
Non-neoplastic PDL-origin lesion, histologically similar to COF but no sharp margin.
Who typically gets Periapical Cemental Dysplasia?
Black females, 40 years old, affecting 2 or more vital lower incisors.
Is Periapical Cemental Dysplasia symptomatic?
No, it is asymptomatic.
What are the radiographic stages of Periapical Cemental Dysplasia?
Starts as radiolucent at apex, then becomes mixed, then radiopaque with radiolucent rim. Continuous with PDL space.
What is the histology of Periapical Cemental Dysplasia?
Fibrous tissue in early stage, cementum-like mass in stroma in mature stage.
What are the differential diagnoses for Periapical Cemental Dysplasia?
RL: granuloma, cyst, COF; RO: odontoma, osteomyelitis, osteoblastoma.
What is the treatment for Periapical Cemental Dysplasia?
None needed.
What is Florid Cemento-Osseous Dysplasia?
Multiquadrant form of periapical cemental dysplasia, also called gigantiform cementoma.
What are the clinical features of Florid Cemento-Osseous Dysplasia?
Middle-aged black females, often familial, painless swelling, affects four quadrants.
Describe the radiographic appearance of Florid Cemento-Osseous Dysplasia.
Poorly defined, lobular, dense radiopaque lesions.
What is the histology of Florid Cemento-Osseous Dysplasia?
Dense acellular cementum-like material.
