periodontology

2

_____ is the aspect of clinical dentistry involved in the prevention, diagnosis, and treatment of diseases of the periodontium

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

29

the base of the sulcus is formed by the ____

junctional epithelium
