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
pyogenic granuloma
- ulcerated, at gingival margin - bleeding is common, highly vascular with chronic inflammatory cells - DD-pregnancy tumor
26
peripheral giant cell granuloma
- 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
Verruca vulgaris
- lips and palate - papillomatous surface with hyperkeratinization and elongated rete ridges - associated with HPV II and IV
28
osteosarcoma
7% of all osteosarcomas occur in the jaws | widening of pdl is common
29
herditary gingival fibromatosis
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
Loe and Silness plaque index
- 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
gingival index
- 0: normal - 1: mild inflammation, slight color change and edema, no BOP - 2: moderate inflammation, redness, edema, BOP - 3: severe inflammation, erythema, edema, ulceration, spontaneous bleeding (brushing, eating, blood on pillow)
32
PSR
- colored probe - worst is when you cannot see colored area, increase with BOP - 1 BOP - 2 colored area visible still but calculus - 3 covering up colored area partially with calc or bop - 4 cannot see colored area
33
O'leary Index
- plaque index - disclosing solution - rinse - count up number of colored surfaces - divide teeth in 4 surfaces and count surfaces and then divide by total number of surfaces
34
NIDR calculus index
- 0: absent calc - 1: supra calc - 2: subG calc
35
Candidiasis
- C albicans - reduced host defense - low pain, red and white lesions, can be scraped from mucosa - in immunocompromised pts - use of the antimycotic/antifungal agents
36
Pemphigus vulgaris
- formation of intraepithelial bullae in skin and mucous membranes - Jews and Mediterranean - Painful erosion, ulcerations - middle age or elderly - Acantholysis
37
Lupus
- autoimmune CT: autoantibodies form to various cellular constituents - irradiating fine white striae with periphery of telangiectasia - lesions can be ulcerated and cannot be differentiated from leukoplakia or atrophic oral lichen planus - butterfly skin lesions - increased width of BM - deposits of various Igs C3 and fibrin along BM
38
Chronic periodontitis
- familial history - poor serum antibody response - older pts - slow progression - attachment loss - calculus and plaque consistent with disease
39
Acantholysis
- canthus layer = stratum spinosum | - breakdown of spinous bridges
40
Periapical cemental dysplasia
- fibrous-osseous cemental lesions: periapical bone is replaced by cellular fibroblastic tissue through a cementoblastic phase - tooth usually vital - asymptomatic - DD- cemento-ossifying fibroma and fibrous dysplasia
41
Clinical signs of TFO
- progressive tooth mobility - fremitus - pathologic migration - Infrabony pockets - buttressing bone - Widened PDL - Trabecular Bone - Angular bone loss, and or furcations
