Age changes of PDL 4

Decrease vascularity, Decrease cells, decrease thickness, increase cementicles

a tissue described as the masticatory mucosa lining the alveolar bone which surrounds the cervical portion of the teeth.

gingiva

moist lining of the oral cavity that is continuous with the exterior surface of the skin on one end and the pharynx on the other end.

Oral mucosa or oral mucous membrane

mucous membrane covers all structure except clinical crowns of the teeth.

Oral mucosa

2 layers oral mucosa

Stratified squamous epithelium, Supporting connective tissue

Outer covering oral mucosa

lining epithelium

Inner connective tissue

Lamina propria

Only one kind of oral mucosa in the mouth

Stratified squamous epithelium (kera or non)

4 functions oral mucosa

Protection, Sensation, Secretion, Temperature regulation

Oral mucosa of deeper tissues against mechanical forces and surface abrasion.

Protection

Oral mucosa Covering the dorm of the tongue

Specialized mucosa

Covers gingiva and hard palate

Masticatory mucosa

Cover all the other parts of mouth Chuck buccal mucosa Alveolar mucosa underneath tongue soft palate

Lining mucosa

buccal mucosa, labial mucosa, alveolar mucosa, floor of the mouth, ventral tongue, soft palate non-keratinized stratified squamous epithelium soft, moist, ability to stretch and compress

Lining mucosa

- attached gingiva, hard palate, dorsal tongue

Masticatory mucosa

dorsal tongue surface associated with the lingual papillae

Specialized mucosa

In between tissues of oral mucosa

Basement membrane

underneath epithelium -attached to the periosteum of the alveolar bone

lamina propria

-Dense thick firm connective tissue containing collagenous fibers.

lamina propria

Underneath lamina propria -contains: - Glands, blood vessels, nerve and adipose tissue.

Submucosa

-thin loose connective tissue with muscle and collagenous fibers different areas varying from 1 another in their structure.

Submucosa

gingiva from the marginal crest to the level of the base of the gingival sulcus.

free gingiva

Space between the tooth and free gingiva.

gingival sulcus

Outer aspect of gingiva in each gingival embrasure tringular gingiva

Gingival/ Interdental Papillae

Is a shallow groove that runs parallel to the marginal crest of the free gingiva.

Free gingival groove

Dense connective tissue with its keratinized stratified squamous epithelium etend from level of the depth of the gingival sulcus.

Attached gingiva

thin, soft tissue that is loosely attached to the underlying alveolar bone. movable covering of maxilla or mndible

Alveolar Mucosa

The transition between keratinized attached gingiva and non-keratinized alveolar mucosa

Mucogingival Junction

Consists of small indentations into the mucosal surtace.

Stipplings of the gingiva

-Compact bone inner and outer plate of alveolar process

Cortical plate

-Fills the areas between plates and alveolar bone proper.

Spongy bone

composed of 65% inorganic material, 35 % organic material.

bone

Age changes • Smoother • Dryer • Atrophic friable • Epithelium becomes thinner • Reduction in filiform papillae • Vascular changes

Gingiva

Compact layer of bone lining the tooth socket

Alveolar bone

a part of the maxilla and the mandible-forms, supports, and lines the sockets into which the roots of teeth fit.

Alveolar process
