periodontics
3
____ is any abnormality or pathological state involving the gingival or supporting tissues of the teeth, commonly used to designate collectively the inflammatory and degenerative disease of the periodontium
periodontal diseaes
4
___ provides a seal around the neck of the tooth and holds the tissue against the tooth during mastication
gingiva
5
_____ suspends and maintains the tooth in its socket
Periodontal Ligament
6
____ anchors the perio ligament fibers to the tooth and protects the dentin
cementum
7
___ surrounds and supports the roots of the tooth
alveolar bone
8
What are the 4 tissues of the periodontium?
1. gingiva
2. cementum
3. PDL
4. alveolar bone
9
Gingiva is composed of a thin outer layer of ____ and an underlying core of ______ ______.
epithelium
connective tissue
10
Four anatomical areas of the ginigiva
1. free gingiva
2. attached ginigiva
3. papillary ginigiva
4. gingival sulcus
11
Coronol boundaries:
gingival margin
12
Apical boundaries:
alveolar mucosa
13
____ separates the free and attached ginigiva
free gingival groove
14
_____: pink attached ginigiva meets the red, shiny alveolar mucosa
mucogingival junction
15
What is the free gingiva composed of?
keratinized stratified squamous epithelium
16
the free gingiva meets the tooth in a thin rounded edge called _____
the gingival margin
17
attached gingiva is composed of what?
keratinized stratified squamous epithelium
18
where is the attached gingiva widest and narrowest?
widest in the incisor and molar regions
narrowest in the premolar regions
19
why is the attached gingiva stippled?
due to the connective fibers that attach the gingival tissue to the cementum and bone
20
function of the attached gingiva
allows the tissue to withstand mechanical forces of mastication, speaking, and toothbrushing
21
______ is the faint depression in the attached gingiva running vertically between the teeth
interdental groove
22
interdental gingiva is composed of what?
keratinized stratified squamous epithelium
23
interdental gingiva consists of 2 interdental ___, facial and lingual
papilla
24
the ___ is a depression in the interdental gingiva
col
25
is the col keratinized? if not, it causes what to start?
it is non-keratinized which causes disease to start
26
what is the function of the interdental gingiva
prevents food from becoming impacted during mastication
27
what is the gingival sulcus composed of?
nonkeratinized stratified squamous epithelium
28
where is the gingival sulcus located?
between the free gingiva and the tooth surface
