poorly mineralized bone => bone distortion and weakening

Question 3

In addition, the teeth may demonstrate generalized————— and often, loss of a well-defined lamina dura around the teeth..

Answer 3

a “cotton wool” appearance.

hypercementosis (multiple teeth)

Question 4

Radiologic Features of Fibrous Dysplasia

Answer 4

1. “ground-glass” appearance with poorly defined margins
2. mixed radiolucent-radiopaque

Question 5

Fibrous dysplasia

Answer 5

an abnormal development
characterized by replacement of normal bone by a proliferation of fibrous tissues.

Question 6

Osteoma

Answer 6

Osteomas are benign tumor of bone

Question 7

Dysplasia

Answer 7

an abnormal development

Question 8

Radiologic Features of Osteoma

Answer 8

circumscribed sclerotic masses ( sclerotic = hardening or thickening => radiopaque)without radiolucent rim

circumscribed= limited, have border; not diffuse

Question 9

Answer 9

Odontogenic tumors (vs bone tumors)
calcified/ radiopaque
a radiolucent rim

Answer 10

(PINDBORG TUMOR)

resembles an ameloblastoma;

radiolucent defect with or without containing fine calcifcations

Question 11

Sialoliths vs Tonsiloliths (radio view, quantity)

Answer 11

Sialoloiths: occlusal, single stone
Tonsiloliths: pano, midportion of ramus; multiple stones

Question 12

Mucositis

Answer 12

thickkeness of sinus mucosa => radiopaque band on the sinus floor, caused by inflammation
