Perio Health; Gingival Diseases/Conditions Flashcards
What is the importance of noticing the periodontal health?
To find the common reference point for assessing disease and determining the meaningful treatment outcomes
What are the clinical features of marginal/free gingiva?
- The portion of the gingiva surrounding the neck of the tooth
- It is not directly attached to the tooth
- Forms the soft tissue wall of the gingival sulcus
- Extends from the gingival margin to the gingival (marginal) groove
What are the clinical features of gingival sulcus?
- Space bounded by the tooth and the free gingiva
- Has the junctional epithelium at its base
- Non-keratinized epithelium
- No rete pegs
- Semi-permeable membrane
What are the clinical features of attached gingiva?
- Portion of the gingiva that extends apically from the area of the free gingival groove to the mucogingival junction
- Normally covered by keratinized epithelium with rete ridges
- No submucosa
- Bound to the underlying tooth and bone
What are the clinical features of interdental gingiva?
- Portion of the gingiva that extends between the teeth
- Includes the Col area which is composed of a nonkeratinized stratified squamous epithelium in the interproximal space
What are the microscopic features of the periodontium?
- oral epithelium
- sucular epithelium
- juncitonal epithelium
What is oral epithelium?
- Keratinized stratified squamous epithelium
- Rete pegs present
- Resistant to forces from mastication
- It has a turnover rate of 30 days
What is sucular epithelium?
- Non-keratinized stratified squamous epithelium
- No rete pegs present
- Semi-permeable membrane
What is junctional epithelium?
- Non-keratinized stratified squamous epithelium
- Hemi-desmosomal and non-collagenous proteins attachment
- Attachment on the tooth is normally at or near the CEJ
- Can be infiltrated by PMN’s
- High rate of turnover (7-10 days)
What are the features of gingival connective tissue?
- Diffuse amorphous ground substance
- Collagen fibers
- Blood vessels in the papillary projections of the connective tissue
The stability of the gingival connective tissue attachment is a key factor in the limitation of the migration of…
junctional epithelium
What is the new term for biologic width?
supracrestal tissue attachment
When plaque is present, the epithelium lining the sulcus is prone to invasion by ____________________________ due to the nature of the type of epithelium
bacteria and their byproducts
Inflammation can initiate and cause the clinical signs of _______________. This can progress to ___________, if left untreated
gingivitis
periodontitis
What are the features of the gingiva?
- Color
- Contour
- Shape
- Size
- Consistency
- Surface texture
- Position
The color of the attached and marginal gingiva displays a range from brown, orange to pink; it results from the colors of the…
- nvascular supply
- the thickness and degree of keratinization of the epithelium
- the pigment containing cells
What should the color of gingiva look like?
- Marginal and attached gingiva are coral pink
- Alveolar mucosa is red, smooth, and shiny
- There can be physiologic pigmentation present
What should the contour of the gingiva look like?
- Scalloped and collar-like
- Gingival level is higher interproximally
What should the shape of the gingiva look like?
The shape of the interdental gingiva is governed by the contour of the proximal tooth surfaces and the location and shape of the gingival embrasures
What should the size of the gingiva look like?
Should corresponds with the sum total of the bulk of cellular and intercellular elements and vascular supply
What should the consistency of gingiva look like?
- Firm and resilient
- The gingival fibers contribute to the firmness of the gingival margin
What should the surface texture of gingiva look like?
- The attached gingiva is stippled; the marginal gingiva is not.
- Stippling varies with age. It is absent during infancy, it appears in some children, it increases until adulthood, and it frequently begins to disappear during old age.
- Stippling is less prominent on lingual than facial surfaces and may be absent in some persons.
What causes stippling?
Microscopically, stippling is produced by alternate rounded protuberances and depressions in the gingival surface.
