Chapter 8 Flashcards
Dysplasia
Abnormal and disordered production of cementum and bone
Not to be confused with dysplasia in context to epithelium
Benign Fribro-Osseous lesions
Periapical cemento-osseous dysplasia
Focal cemento-osseous dysplasia
Florid cemento-osseous dysplasia
Fibrous dysplasia
Periapical cemento-osseous dysplasia
Common disease of unknown cause that affect periapical bone
Most commonly on mandible anterior
Predilection: Black women
Teeth in the affected area are vital
Florid-cemento osseous dysplasia
A condition of disordered cementum and bone development
Usually occurs in black women over 40
Affect more than one quadrant
Masses of irregular opacification are noted that are composed of dense sclerotic bone, cementum, or both
Florid cemento-osseous dysplasia
Asymptomatic fibro-osseous lesion
Focal cemento-osseous dysplasia
Focal cemento-osseous dysplasia
Occurs in women between 30 and 50 Caucasian individuals Occurs in posterior mandible Isolated well-delineated radiolucent to radiopaque lesion Less than 1.5 cm in size
Replacement of bone with abnormal fibrous connective tissue interspersed with varying amounts of calcification
Fibrous dysplasia
Fibrous dysplasia
Patient will experience painless, gradual, unilateral enlargement of the maxilla or mandible
Ground glass radiopaque appearance of the lesion radiographically
Types of fibrous dysplasia
Monostotic fibrous dysplasia
Polyostotic fibrous dysplasia
Involvement of a single bone
Monostotic fibrous dysplasia
Monostotic fibrous dysplasia
Most common form of fibrous dysplasia
Maxilla more frequently involved
Most commonly in children and young adults
Painless swelling or bulging of the buccal plate
Involvement of more than one bone
Polyostotic fibrous dysplasia
Polyostotic fibrous dysplasia
Typically occurs in children, female predilection
When long bones are involved, they may exhibit bowing and an associated dull aching pain
Patients may have skin lesions appearing as light-brown macules called cafe au lait spots
Polyostotic fibrous dysplasia radiographically
Diffuse radiopacity looking like ground glass
Types of polyostotic fibrous dysplasia
Craniofacial fibrous dysplasia
Jaffe types
Albright syndrome
Involves the maxilla with extension into the sinuses and adjacent zygoma, sphenoid, and occipital bones
Craniofacial fibrous dysplasia
Involves multiple bones along with cafe au lait macules on the skin
Jaffe types
Characterized by endocrine abnormalities, precocious puberty in females, stunting or deformity of skeletal growth in both sexes as a result of premature closing of the epiphyseal plate, cafe au lait spots
Albright syndrome
A chronic metabolic bone disease
Commonly in men over age 50
Enlargement of affected bone
Paget disease of bone
Paget disease of bone
Resorption, osteoblastic repair, and remineralization of involved bone
Maxilla more commonly affected. Other bones may also be affected including femur or pelvis
Paget disease of bone radiographically
Cotton wool
Serum alkaline phosphate level is significantly elevated in active disease
Paget disease of bone
Aneurysmal bone cyst
Pseudocyst
Blood-filled spaces surrounded by multinucleate giant cells and fibrous connective tissue
Radiographic: Honeycomb or soap bubbles
