Periodontium

Front 1

Periodontium

Back 1

functional system of tissues that surround the teeth and attaches them to jaw and bone

"supporting tissues of teeth"

"the attachment apparatus"

Front 2

Gingiva

Back 2

part of the mucosa that surrounds the cervical portions of the teeth and covers the alveolar processes of the jaws

Front 3

Periodontal Ligament

Back 3

a thin sheet of fibrous connective tissue that surrounds the roots of the teeth and joins the root cementum with the bone of the tooth socket

Front 4

Cementum

Back 4

a mineralized layer of connective tissue that covers the root of the tooth

-anatomically, cementum is part of the tooth

-it is also part of the periodontium

Front 5

Alveolar Bone

Back 5

-bone that surrounds the roots of the teeth

-forms he bony sockets that support and protect the roots of the teeth

Front 6

Gingival margin

Back 6

the thin, rounded edge of free gingiva that forms the coronal boundary, or upper edge of the gingiva

(healthy=slightly coronal to CEJ)

Front 7

Alveolar mucosa

Back 7

apical boundary of gingiva

dark red color and smooth, shiny surface

Front 8

Free gingival groove

Back 8

shallow linear depression that separates the free and attached gingiva

may be visible but not obvious

Front 9

Mucogingival junction

Back 9

clinically visible where pink attached gingiva meets the red, shiny alveolar mucosa

Front 10

Free gingiva

Back 10

the unattached portion that surrounds the tooth in the region of the CEJ

aka unattached gingiva or marginal gingiva

Front 11

Attached gingiva

Back 11

part of the gingiva that is firm, dense and tightly connected to cementum on cervical third of the root or the periosteum (connective tissue cover) of the alveolar bone

Front 12

Stippling

Back 12

the dimpled appearance, similar to an orange peel that may be visible on the surface of the attached gingiva

Front 13

Interdental gingiva

Back 13

the portion of the gingiva that fills interdental embrasure between two adjacent teeth apical to the contact area

consists of two interdental papillae (facial, lingual)

Front 14

Gingival sulcus

Back 14

the space between the free gingiva and the tooth surface

Front 15

Gingival crevicular fluid

Back 15

fluid that flows into the sulcus from the adjacent gingival connective tissue

the flow is slight in health and increases in disease

Front 16

Alveolar process

Back 16

the bone of the upper or lower jaw that surrounds and supports the roots of the teeth

Front 17

Alveolar Bone

Back 17

the bone that surrounds the roots of the teeth. it forms the bony sockets that support and protect the roots of the teeth

Front 18

Alveolar bone proper (cribiform plate)

Back 18

thin layer of bone that lines the socket to surround the root of the tooth. ends of PDL extend here

Front 19

Alveolus

Back 19

the bony socket; a cavity in the alveolar bone that houses the root of a tooth

Front 20

Cortical Bone

Back 20

a layer of compact bone that forms the hard, outside wall of mandible and maxilla on facial and lingual aspects, surrounds the alveolar bone proper and gives support to the socket

Front 21

Alveolar crest

Back 21

the most coronal portion of the alveolar process. in health 1-2 mm below CEJ

Front 22

Cancellous bone

Back 22

the lattice like bone that fills the interior portion of the alveolar process between the cortical bone and alveolar bone proper

Front 23

Periosteum

Back 23

a dense membrane composed of fibrous CT that closely wraps the outer surface of the alveolar bone; consists of outer layer of collagenous tissue and inner layer of fine elastic fibers

Front 24

Innervation

Back 24

nerve supply - trigeminal nerve

Front 25

Anastomose

Back 25

to join together; in the periodontium; a complex system of blood vessels supplies blood to periodontal tissues

Front 26

Lymphatic System

Back 26

a network of lymph nodes connected by lymphatic vessels that plays an important role in the bodys defense against infection
