1

Dysplasia

Abnormal and disordered production of cementum and bone
Not to be confused with dysplasia in context to epithelium

2

Benign Fribro-Osseous lesions

Periapical cemento-osseous dysplasia
Focal cemento-osseous dysplasia
Florid cemento-osseous dysplasia
Fibrous dysplasia

3

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

4

Florid-cemento osseous dysplasia

A condition of disordered cementum and bone development
Usually occurs in black women over 40
Affect more than one quadrant

5

Masses of irregular opacification are noted that are composed of dense sclerotic bone, cementum, or both

Florid cemento-osseous dysplasia

6

Asymptomatic fibro-osseous lesion

Focal cemento-osseous dysplasia

7

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

8

Replacement of bone with abnormal fibrous connective tissue interspersed with varying amounts of calcification

Fibrous dysplasia

9

Fibrous dysplasia

Patient will experience painless, gradual, unilateral enlargement of the maxilla or mandible
Ground glass radiopaque appearance of the lesion radiographically

10

Types of fibrous dysplasia

Monostotic fibrous dysplasia
Polyostotic fibrous dysplasia

11

Involvement of a single bone

Monostotic fibrous dysplasia

12

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

13

Involvement of more than one bone

Polyostotic fibrous dysplasia

14

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

15

Polyostotic fibrous dysplasia radiographically

Diffuse radiopacity looking like ground glass

16

Types of polyostotic fibrous dysplasia

Craniofacial fibrous dysplasia
Jaffe types
Albright syndrome

17

Involves the maxilla with extension into the sinuses and adjacent zygoma, sphenoid, and occipital bones

Craniofacial fibrous dysplasia

18

Involves multiple bones along with cafe au lait macules on the skin

Jaffe types

19

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

20

A chronic metabolic bone disease
Commonly in men over age 50
Enlargement of affected bone

Paget disease of bone

21

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

22

Paget disease of bone radiographically

Cotton wool

23

Serum alkaline phosphate level is significantly elevated in active disease

Paget disease of bone

24

Aneurysmal bone cyst

Pseudocyst
Blood-filled spaces surrounded by multinucleate giant cells and fibrous connective tissue
Radiographic: Honeycomb or soap bubbles

25

Osteomalacia

Result of vitamin D deficiency and induced by certain tumors
Rickets
Hypophosphatemic vitamin D-resistant ricketts

26

Clinical characteristics of osteomalacia

Delayed tooth eruption
Peridontal disease
Pathologic fractures
