HERS WILL MAKE CEMENTUM

- rubbery, resilient keratinized or parakeratinized stratified squamous epithelium

cementicles completely covered by secondary cementum

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

In between tissues of oral mucosa

-Fills the areas between plates and alveolar bone proper.

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

cementoblast came from

fills the resorption lacunae collagen fibers forms cementoblast

island of cells coming from HERS form _

most organic matter of cementum is

-Compact bone inner and outer plate of alveolar process

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

cementum on top of enamel

Has cervical loop

Fibers produced by cementoblast no sharpeys fibers FIRST FORMED BEFORE PDL FORMS 15-20 microns

- attached gingiva, hard palate, dorsal tongue

Space between the tooth and free gingiva.

Consists of small indentations into the mucosal surtace.

2 layers oral mucosa

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

terminal ends of collagen fibers tht will be embedded into cementoid

in multi rooted teeth, two or more teeth the collgen fibers found between root or furction

Oral mucosa Covering the dorm of the tongue

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

elongated cervical loop

underneath epithelium -attached to the periosteum of the alveolar bone

created when theres cementum repair after resorption demarkation between repaired and old cementum

gingiva in crown region covering crown as age, gingiva more on apical location APICAL MOVEMENT OR MIGRATION OF GINGIVAL

4 functions oral mucosa

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

found on apex of tooth and forcation of molar collagen fibers from combination of sharpeys and cementoblasts

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

Principal cementum for attachment

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

3 attachment apparatus

Majority of cementum is

Outer aspect of gingiva in each gingival embrasure tringular gingiva

Age changes of PDL 4

acellular fibrillar cementum

cementum on enamel

cementum contains collagen fibers from cementoblast

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

epithelial rest of malassez can be calcified turning epithelial cells into tiny stones in PDL called

oblique/horizontal more fine, smaller

Compact layer of bone lining the tooth socket

5 gingival ligaments

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.

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

Inner connective tissue

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

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

guide the root formation

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

dorsal tongue surface associated with the lingual papillae

Parallel to CDJ larger

repair of root resorption is

-Dense thick firm connective tissue containing collagenous fibers.

Outer covering oral mucosa

Inner cortical plate

Only one kind of oral mucosa in the mouth

Covers gingiva and hard palate

newly formed cementum not yet mineralized it contains

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

5 alveolodental ligament

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