Periodontal Health Gingival Disease/Conditions Flashcards
In looking at the gingiva, it is either:
in health or disease
Periodontal health- What is the importance?
To find the common reference point for assessing disease and determining the meaningful treatment outcomes
The portion of the gingiva surrounding the neck of the tooth:
marginal/free gingiva
Describe the attachment of the marginal/free gingiva:
Not directly attached to the tooth
The marginal/free gingiva forms:
The soft tissue wall of the gingival sulcus
Marginal/free gingiva extends from:
gingival margin to the gingival (marginal) groove
Space bounded by the tooth and the free gingiva:
gingival sulcus
The gingival sulcus has ______ as its base
junctional epithelium
The gingival sulcus is comprised of _______ epithelium
non-keratinized
No ____ are present in the gingival sulcus
Rete pegs
The gingival sulcus is considered a _____ membrane
semi-permeable
Portion of the gingival that extends apically from the area of the free gingival groove to the mucogingival junction:
attached gingiva
The attached gingiva is normally covered by:
keratinized epithelium with rete ridges
No _____ is present in the attached gingiva
submucosa
The attached gingiva is bound to the:
bound to the underlying tooth and bone
Portion of the gingiva extends between the teeth:
interdental gingiva
Includes the Col area which is composed of a non-keratinized stratified squamous epithelium in the interproximal space:
interdental gingiva
Describe the gingival col:
Area comprised of a non-keratinized squamous epithelium in the interproximal space
What is the cellular makeup of the gingival col?
non-stratified squamous epithelium
The gingival col is found in what area of gingiva?
interdental gingiva
Microscopic features of the anatomy of the periodontium includes: (3)
- oral epithelium
- sulcular epithelium
- junctional epithelium
The oral epithelium is comprised of:
Keratinized stratified squamous epithelium
Describe the turnover rate of the oral epithelium:
turnover rate of 30 days
The sulcular epithelium is comprised of:
Non-keratinized stratified squamous epithelium
Rete pegs are present in the sulcular epithelium. The sulcular epithelium is considered a semi-permeable membrane.
First statement false; second statement true
The juncntioal epithelium is comprised of:
non-keratinized stratified squamous epithelium
The junctional epithelium is attached to the tooth with:
hemidesmosomes
The junctional epithelium can be infiltrated by:
PMNs
Describe the rate of turnover for the junctional epithelium:
high rate of turnover (7-10 days)
- keratinized epithelium
- rete pegs present
- resistant to forces of mastication
oral epithelium
- non-keratinized epithelium
- no rete pegs present
- semi-permeable membrane
sulcular epithelium
- non-keratinized epithelium
- hemi-desmosomal and non-collagenous proteins attachment
- attachment on the tooth is normally at or near the CEJ
- can be infiltrated by PMNs
junctional epithelium
- diffused amorphous ground substance
- collagen fibers
- blood vessels in the papillary projections of the connective tissue
gingival connective tissue
Forms the connective tissue attachment of the junctional epithelium:
densely packed collagen fibers
