Q

what is the mucogingival junction

A

the junction betwwen the attached gingiva and alveolar mucosa

32
Q

where is a mucogingival junction not found

A

Not in the Palate

33
Q

what type of people tend to have free gingival grooves

A

Those that also have stippling

34
Q

roll of the attached gingiva

A

Supports marginal gingiva
Base for moveable elements (lips, cheek, tongue)
Withstand Functional stress
Barrier for passage of inglammation

35
Q

how does the attached gingival withstand frictional and functional stresses

A

Thick CT layer

Firmly bound to periosteum and bone

36
Q

does thickness of attached gingiva mayyer to healthy patients

A

No

37
Q

what characteristics of gingiva matter for prevention of inflammation

A

Width

Thickness

38
Q

what part of the mouth does not have a mucogingival junction

A

palate (no non-keratinized tissue, so no junction possible)

39
Q

what is width of the gingiva

A

the height (apical to coronal)

40
Q

what is the thickness of gingival

A

tooth to facial/lingual dimension

41
Q

what does the shape of the interdental papilla depend on

A

The contact relationships between adjacent teeth
With of approximal tooth surfaces
Course of CEJ

42
Q

what is the Col

A

Concavity seen in contact areas of premolar/molar region

43
Q

what type of epithelium makes up the col

A

Non-keratinized epithelium( similar to junctional)

44
Q

when does the papilla completely fill the space between teeth

A

when the distance from the contact point to the crest of the bone is less than 5 mm

45
Q

problem with the dental papilla

A

greatest susesptibility to perio disease

46
Q

what happens to the interdental papilla if there is space between the teeth

A

disappears

47
Q

does the interdental papilla reappear once teeth come back into contact

A

Yes

48
Q

size demensions for black triangles

A
  • less then 5mm between bone crest and contact point: no black triangles
  • less than 6mm: 50% loose
  • less than 7mm: 75% loose papilla
49
Q

if tooth is removed what happens to dental papilla

A

Does go away, but can come back if you fill space quickly

50
Q

The base(bottom) of the gingival sulcus in a healthy mouth is positioned apical to the CEJ. When is this condition most likely to occur?

A

at ages 40-60 years old

51
Q

what are the cells of the oral epithelium

A

KEratinized, stratified, squamous epithelium (keratinocytes)

52
Q

layers of the oral epithelium

A

Basal layer (stratum basale or stratum germinativum)
PRickle cell later (stratum spinosum)
Granular cell layer (stratum granulosum)
Keratinized cell layer (stratum corneum)

53
Q

what types of cells make up the keratinized cell layer of the oral epithelium

A

Orthokeratinized (no nucleus)

Parakeratinized (nuclear remnanats)

54
Q

what cells can devide in the oral epithelium

A

BAsal layer

55
Q

what happens to cells as you move from the basal layer in oral epithelium

A 
more desmosomes
Less leaky
more dense
less active
less organelles
more keratin/tonofilaments
56
Q

why does the oral epithlium want to be leaky

A

so nutrients and blood can get to the more superficial layers

57
Q

what are the 2 types of cells of the oral epithlium

A

Keratinocytes

Clear cells

58
Q

what are the clear cells of the oral epithlium

A

Melanocytes
Langerhans cells
Merkel’s cells

59
Q

Roll of lnagerhans cells

A

Defensive cells

60
Q

Roll of Merkel’s cells

A

Sensory

61
Q

where is the basement membrane found

A

Present between basal layer of oral epithlium and CT

62
Q

size of the basement membrane

A

1-2 micrometers wide

63
Q

what is found in basements membrane

A

Rich in glycoproteins

Protein-polysacccharide complexes

64
Q

roll of glycoproteins in basement membranes

A

Space maintainers

keeps tissues hydrated

65
Q

layers of the basement membarnes

A

Lamina Lucida

Lamina Densa

66
Q

what is the lamina lucida next to

A

Adjacent to basal cells

67
Q

what is the lamina densa next to

A

Connective tissue

68
Q

what attaches the lamina densa to connective tissue

A

anchoring fibers

69
Q

what attaches the lamina lucida to the epithelium

A

Hemidesmosomes

70
Q

what is a desmosomes

A

Pair of hemidesmosomes

71
Q

what is the morphology between the Oral epithlium and connective tissues

A

Connective tissues projects into epithelium via Connective tissue Papillae

72
Q

what are the projections of eptihlium to the connective tissue

A

Epithelial eidges or rete pegs

73
Q

where are REte pegs not found

A

At Junctional epithlium sites

74
Q

what causes Stippling

A

Rete pegs fusing

75
