functional system of tissues that surrounds the teeth and attaches them to the jaw bone. AKA attachment apparatus


tissue that covers the cervical portions of teeth and the alveolar processes of the jaws

Periodontal ligamament (PDL)

fibers that surround the root of the tooth. These fibers attach to the bone of the socket on one side and the cementum of the root on the other side.


thin layer of mineralized tissue that covers the root of the tooth

Alveolar bone

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

Gingival margin

thin, rounded edge of the free gingiva that forms the coronal boundary of the gingiva. In health, it contacts the tooth slightly coronal to the CEJ

Alveolar mucosa

the apical boundary of the gingiva; dark red, smooth and shiny

Free gingival groove

a shallow linear depression that seperates the free and attached gingiva. It may or may not be visible clinically

Mucogingival junction

Clinically visible boundary where pink attached gingiva meets red, shiny alveolar mucosa

Free gingiva

unattached portion of the gingiva that surrounds the tooth in the region of the CEJ AKA unattched or marginal gingiva

Attached gingiva

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


dimpled appearance that may be visible on surface of attached gingiva

Interdental gingiva

portion of the gingiva that fills the interdental embrasure between 2 adjacent teeth apical to the contact area. Consists of 2 interdental papillae

Gingival sulcus

space between the free gingiva and the tooth surface

Gingival crevicular fluid

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

Alveolar process

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

alveolar bone proper

the thin layer of bone that lines the socket to surround the root of the tooth (AKA cribriform plate); the ends of the PDL fibers are embedded here


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

Cortical bone

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

Alveolar crest

the most coronal portion of the alveolar process. In health, it is located 1-2 mm apical to the CEJ

Cancellous bone

Lattice-like bone that fills the interior portion of the alveolar process between the cortical bone and the alveolar bone proper. It is oriented around the tooth to form support for the alveolar bone proper


Dense membrane composed of fibrous connective tissue that closely wraps the outer surface of alveolar bone.

Composed of outer layer of collagenous tissue, inner layer of fine elastic fibers


to join together

Periodontium is supplied by a complex system of blood vessels

Trigeminal nerve

innervates the periodontium

Lymphatic system

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

Lymph nodes

small, bean shaped structures located on either side of head, neck, armpits, groin.

Filter out and trap baceria, fungi, and viruses and eliminate them
