Q

junctional epithelium

A
  • description: non keratinized, encircles the tooth
  • size: 15 to 20 cells thick, 1-2 cells at the apical end
  • position: in health is longer than in disease. can migrate along the root surface
  • relation: of crest of alveolar bone to the attached gingival tissue - base of attachment to the crest of alveolar bone is 1-1.5 mm
  • attachment: of the epithelium to the tooth surface - provides a seal at the base of the sulcus

Q

Q

clinically normal gingiva should be:

A
  • coral pink (greyish pink)
  • pyramid shaped papilla

Q

early recognition of tissue changes

A
  • significant changes such as moderate to severe generalized redness, enlargement, sponginess, deep pockets, and mobility are easy to detect with good light and accessibility
  • subtle changes are more difficult to assess
  • early recognition and treatment is the key to the success of gingival and periodontal infections, as clinicians we must be on the ball with our assessment skills

Q

signs of health in colour of gingiva

  • signs of health:
    1. pale pink - darker in darker complexions
    2. factors influencing colour:
  • vascular supply
  • thickness of epithelium
  • degree of keratinization
  • physiologic pigmentation

Q

changes in disease in colour of gingiva

A
  • changes in disease:
    1. in chronic inflammation: dark red to bluish tone
    2. in acute inflammation: bright red
    3. extent: deep involvement expected when diffuse colour changes extend:
  • into attached gingiva
  • from marginal gingiva to mucogingival junction
  • through into alveolar mucosa

Q

signs of health in size of gingiva

A
  • signs of health:
    1. free gingiva: skinny, fits snuggly around tooth
    2. attached gingiva: varies amongst teeth and individuals - approx. 1-9 mm

Q

changes in disease in size of gingiva

A
  • changes in disease
    1. free gingiva: becomes enlarged, col deepens as papillary size increases
    2. attached gingiva: decreases in amount as pocket deepens

Q

signs of health in contour of gingiva

A
  • signs of health:
    1. free gingiva:
  • curved line, knife edged
  • papilla contact teeth
  • diastema areas are flatter

Q

changes in disease in contour of gingiva

A
  • changes in disease:
    1. free gingiva:
  • rounded or rolled
  • papilla blunted/flattened, bulbous or cratered
17
Q

two types of stillman’s clefts

A
  1. v-shaped stillman’s

2. slitlike stillman’s

18
Q

signs of health in the consistency of gingiva

A
  • signs of health:

- firm when palpated with side of a blunt instrument, ie probe

19
Q

changes in disease in contour of gingiva

A
  • changes in disease:
  • soft, spongy, red
  • smooth and shiny with loss of stippling
  • marginal enlargement
  • bleeds easily upon probing
  • firm fibrotic purplish if inflammation is severe
  • bleeds in deeper part of pocket when probed. delayed BOP
  • free gingiva is easily retracted from tooth with air or probe
20
Q

signs of health in the surface texture of gingiva

A
  • signs of health:
    1. free gingiva: smooth
    2. attached gingiva: stippled
    3. interdental gingiva: is smooth with stippling in the middle
21
Q

changes in disease in the surface texture of gingiva

A
  • changes in disease:
    1. inflammatory: loss of stippling, smooth, shiny surface
    2. hyperkeratosis: leathery, hard, nodular
22
Q

what are the 3 C’s in gingival health

A
  • colour
  • contour (shape and size)
  • consistency (texture)
23
Q

what is festooned rolling

A
  • exaggerated rolling
24
Q

where should the gingival margin be in healthy gingiva

A
  • at or slightly below the prominence of the cervical third of the tooth
25
Q

what can occur with gingival enlargement

A
  • the gingival margin is higher on the tooth than normal
26
Q

effects of gingival recession

A
  1. definition: exposure of root surface as a result of apical migration of the JEA
  2. actual recession: the distance from the CEJ to the JEA
  3. visible recession: exposed root surface visible on clinical examination. CEJ to the gingival margin
  4. localized recession: deep or shallow, narrow or wide
  5. measurement: can be measured with a probe
27
Q

what is CAL

A
  • clinical attachment loss

- the ‘actual’ recession

28
Q

bleeding in gingiva

A
  • healthy tissues do not bleed
  • changes with disease indicated by bleeding on probing (BOP)
  • sulcular epithelium becomes disease pocket epithelium
29
Q

signs of health in the gingiva of the primary dentition:

A
  • pink or slightly red, rolled or rounded, less fibrous and not tightly adapted to teeth, may not be stippled, width of attached gingiva about 1-6 mm
  • interdental papillae: anterior diastemata often present and papillae are flat or saddle shaped
30
Q

signs of health in the mixed dentition

A
  • constant state of change
  • free gingiva can be rolled or rounded, slightly red, shiny, and lack firmness
  • clinical crown depends upon stage of eruption
31
Q

changes in disease in the gingiva of young children

A
  • periodontal tissues are examined the same in children as in adults
  • probe the adult teeth only
  • do not probe erupting teeth
  • gingivitis occurs frequently periodontitis can occur but is rare
  • mucogingival tissues are of relevance to children and need to be examined closely especially if considering orthodontics
32
Q

mobility

A
  • charted/noted in ‘grade’
    1 = slight mobility detected beyond normal, up to 1 mm horizontal displacement
    2 = moderate mobility, greater than 1 mm but less than 2 mm displacement
    3 = severe mobility, greater than 2 mm may move in all directions including vertical as well as horizontal
  • chart notation is made on tooth diagram
33
Q

furcation involvement (classes) and symbols (descriptions)

A
  • class I: able to detect with probe (not necessary to see it, but can feel the furcation of roots with probe), symbol is upside down triangle with open top
  • class II: able to get probe into furcation (symbol is upside down triangle with closed top
  • class III: probe can go through entire furcation, symbol is filled in upside down triangle
  • class IV: visible through and through, symbol same as III
