surgical recontouring of bone for cosmetic reasons

A

polyostotic fibrous dysplasia

25

maloclussion, tipping and displacement of teeth
ground glass
maxilla common/painless/facial assymetry

A

fibrous dysplasia

26
Q

chronic metabolic bone disease; resorption, osteoblastic repair, and remineralization of involved bone; unknown cause(could be virus); men over age 50
maxilla commonly affected

A

paget disease of bone

27
Q

paget disease is also called

A

osteitis deformans

28
Q

enlargement is common; pain; spaces increase between teeth as bone enlarges ; may cause prosthesis to fit incorrectly

A

paget disease

29
Q

radiograph: cotton wool; hypercementosis, loss of lamina dura

A

paget disease of bone

30
Q

microscopically/histologically- reversal lines; mosaic bone pattern(numerous osteoblasts and clasts on surface in bony trabeculae pattern)

A

paget disease of bone

31
Q

the serum alkaline phosphatase level is elevated in active disease; prominent reversal lines may create a pattern known as mosaic bone
treatment is experimental-slowly progressive disease(no cure)

A

paget disease of bone

32
Q

chronic progressive condition
enlargement of the jaws, pain, neurologic complaints, increase spacing, loosening of teeth, cotton wool radiopaque pattern

A

pagets

33
Q

well-vascularized ct containing multinucleated giant cells; occurs within bone; in children and young adults

A

central giant cell granuloma

34
Q

anterior maxilla or mandible; young adults; may cause resorption or divergence of tooth roots; teeth are asymptomatic and VITAL; surgical excision

A

central giant cell

35
Q

what is a lesion of bone that is radiographically identical to central giant cell

A

brown tumor

36
Q

in patients with hyperparathyroidism is also very similar microscopically to what

A

central giant cell

37
Q

a disease of bone that develops over a long period of time

  • result of calcium deficiency
  • young children(deficency in vit D)
  • adults(may be related to various health problems such as malabsorption syndrome)
A

osteomalacia

38
Q

may be associated with delayed tooth eruption and periodontal disease

A

osteomalacia

39
Q

an inherited form of vit D deficiency is called what

A

hypophosphatemic vit D-resistant rickets

40
Q

osteomalacia–when this disease occurs in young children, it is usually caused by a nutritional deficiency of vit D,and associated with disease–?

A

rickets

41
Q

have large pulp chambers with very long pulp horns; dentin has pronounced cracks, which leads to pulpal infections and fractures in enamel

A

hypophosphatemic vitamin D- resistant rickets
