17
Q

Primary TFO

A

-excessive force on normal teeth

18
Q

Secondary TFO

A

-normal force on compromised teeth

19
Q

Fremitus

A

-shaking of teeth when they come into occlusion

20
Q

Pathologic migration

A
  • movement of teeth due to disease

- usually happens during chronic periodontitis

21
Q

Co-destruction

A
  • TFO plus periodontitis could impact progression of disease

- alters severity and pattern of inflammatory periodontal disease

22
Q

pyogenic granuloma

A

-pregnancy tumor

23
Q

AA

A
JP2 clone serotype B
facultative anaerobe, nonmotile 
leukotoxins
LPS
Collagenases
Immunosuppressive factors
translocate across JE and invade CT
24
Q

Fibroma/fibrous hyperplasia

A
  • caused by irritation
  • DD- giant cell fibroma
  • sessile, well-circumscribed, smooth surfaced nodules
25
Q

pyogenic granuloma

A
  • ulcerated, at gingival margin
  • bleeding is common, highly vascular with chronic inflammatory cells
  • DD-pregnancy tumor
26
Q

peripheral giant cell granuloma

A
  • anywhere on mucosa
  • red or purple
  • focal collection of multi-nucleated osteoclast like giant cells with richly cellular and vascular stroma separated by collagenous septa
  • probably originated from periodontal ligament
27
Q

Verruca vulgaris

A
  • lips and palate
  • papillomatous surface with hyperkeratinization and elongated rete ridges
  • associated with HPV II and IV
28
Q

osteosarcoma

A

7% of all osteosarcomas occur in the jaws

widening of pdl is common

29
Q

herditary gingival fibromatosis

A

diffuse gingival enlargement
may interfere with or prevent tooth eruption
possible mechanism: TGF-B1 favor accumulation of ECM
may be located on chromosome 2 (defect in Son of Sevenless-1 gene)

30
Q

Loe and Silness plaque index

A
  • 0: no plaque
  • 1: film of plaque adhering to the free gingival margin
  • 2: moderate accumulation of soft deposit within gingival pocket or tooth and gingival margin
  • 3: abundance of soft matter within the gingival pocket or on tooth and gingival margin
31
Q

Q

PSR

A
  • colored probe
  • worst is when you cannot see colored area, increase with BOP
  • 1 BOP
  • 2 colored area visible still but calculus
