Periodontium |
functional system of tissues that surround the teeth and attaches them to jaw and bone "supporting tissues of teeth" "the attachment apparatus" |
|
Gingiva |
part of the mucosa that surrounds the cervical portions of the teeth and covers the alveolar processes of the jaws |
|
Periodontal Ligament |
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 |
|
Cementum |
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 |
|
Alveolar Bone |
-bone that surrounds the roots of the teeth -forms he bony sockets that support and protect the roots of the teeth |
|
Gingival margin |
the thin, rounded edge of free gingiva that forms the coronal boundary, or upper edge of the gingiva (healthy=slightly coronal to CEJ) |
|
Alveolar mucosa |
apical boundary of gingiva dark red color and smooth, shiny surface |
|
Free gingival groove |
shallow linear depression that separates the free and attached gingiva may be visible but not obvious |
|
Mucogingival junction |
clinically visible where pink attached gingiva meets the red, shiny alveolar mucosa |
|
Free gingiva |
the unattached portion that surrounds the tooth in the region of the CEJ aka unattached gingiva or marginal gingiva |
|
Attached gingiva |
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
|
|
Stippling |
the dimpled appearance, similar to an orange peel that may be visible on the surface of the attached gingiva |
|
Interdental gingiva |
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) |
|
Gingival sulcus |
the space between the free gingiva and the tooth surface |
|
Gingival crevicular fluid |
fluid that flows into the sulcus from the adjacent gingival connective tissue the flow is slight in health and increases in disease |
|
Alveolar process |
the bone of the upper or lower jaw that surrounds and supports the roots of the teeth |
|
Alveolar Bone |
the bone that surrounds the roots of the teeth. it forms the bony sockets that support and protect the roots of the teeth |
|
Alveolar bone proper (cribiform plate) |
thin layer of bone that lines the socket to surround the root of the tooth. ends of PDL extend here |
|
Alveolus |
the bony socket; a cavity in the alveolar bone that houses the root of a tooth |
|
Cortical Bone |
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 |
|
Alveolar crest |
the most coronal portion of the alveolar process. in health 1-2 mm below CEJ |
|
Cancellous bone |
the lattice like bone that fills the interior portion of the alveolar process between the cortical bone and alveolar bone proper |
|
Periosteum |
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 |
|
Innervation |
nerve supply - trigeminal nerve |
|
Anastomose |
to join together; in the periodontium; a complex system of blood vessels supplies blood to periodontal tissues |
|
Lymphatic System |
a network of lymph nodes connected by lymphatic vessels that plays an important role in the bodys defense against infection |
