1

What makes up the masticatory mucosa?

-keratinized stratified squamous epithelium -Dorsum of tongue, hard palate, and attached gingiva

2

what is the lining of the mucosa made up of?

-non-keratinized stratified squamous epithelium -buccal mucosa -labial mucosa

3

what is the specialized mucosa component of the oral mucosa?

-dorsum of the tongue

-taste buds, lingual papillae

4

which 3 mucosa make up the oral mucosa

-masticatory mucosa -lining mucosa -specialized mucosa

5

what are 2 histologic features of the masticatory epithelium?

-keratinized -rete pegs (rete processes, rete ridges)

6

what are rete pegs?

-downward thickening of epidermis between the dermal papillae -they function in helping keratinized tissues resist forces during mastication

7

what 3 main layers comprise the basement membrane?

-basal lamina -attaching proteins -lamina reticularis

8

the basal lamina consists of the lamina lucida and lamina densa. what are the main molecules in each layer?

lamina lucida: -laminin -integrins -entactins -dystroglycans lamina densa: -collagen IV

9

what two proteins make up the attaching proteins of the basement membrane?

-collagen VII -fibrillin

10

what makes up the lamina reticularis of the basement membrane

-collagen III

11

what are langerhans cells?

antigen-presenting cells that are important for immune system functions

12

what 4 main components make up the peridontium?

-gingiva -cementum -periodontal ligament -alveolar supporting bone

13

what are 3 types of gingiva?

-attached -unattached (margina, free) -interdental

14

T or F: periodontal tissues are biologically interdependent and withstand changes with age and disease.

false: they are subject to variations and changes with age and disease

15

what 4 tissues does the periodontium NOT include?

-enamel -dentin -pulp -surrounding bone of the alveolar process

16

what are the 5 main functions of the periodontium?

-attach -resist -maintain -adjust -defend

17

describe characteristics of periodontium functions

-tooth support
-shock absorber: withstand forces of mastication
-sensory receptor necessary for proper positioning of the jaw
-nutritive: blood vessels provide the essential nutrients to the vitality of the PDL

18

what are 5 components of the gingival epithlium?

-keratinocytes -desmosomes -tonofilaments -basal lamina -hemidesmosomes

19

4 anatomical areas of the gingiva

-free gingiva (marginal) -gingival sulcus -interdental gingiva (papilla) -attached gingiva

20

what is the difference between the gingival sulcus and the periodontal pocket?

-gingival sulcus implies health -periodontal pocket implies disease

21

what are the gingival boundaries?

-upper (coronal) edge is the gingival margin -lower (apical) edge is the alveolar mucosa

22

Name these tissues:

23

what part of the gingival sulcus does the free gingiva form?

soft tissue wall

24

T or F:

free gingiva tissues meets the tooth in a thin, rounded edge called the gingival margin

true

25

what type of tissue makes up the free gingiva?

keratinized stratified squamous epithelium

26

T or F:

the gingival margin does not follow the contours of the teeth

false:

it follows the contours of the teeth, creating a wavy outline

27

what are the two gingival biotypes?

28

compare thin vs thick gingival biotypes

thin biotype:

  • 1/3 sample, females
  • slender teeth
  • narrow zone of KG

thick biotype

  • 2/3 sample
  • quadratic teeth
  • wide zone of KG

29

what is the gingival sulcus?

the space between the free gingiva and tooth surface

30

what are 4 characteristics of the gingival sulcus?

-V-shaped shallow space around the tooth

-clinically normal sulcus is 1-3 mm as measured by a probe

-base of sulcus is formed by junctional epithelium

-wall of sulcus is non-keratinized
