4 Tissues of the Periodontium

Gingiva
The part of mucosa that surrounds cervical portions
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
of teeth and covers alveolar processes of the jaws.
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Periodontal Ligament [PDL] ||\\||\\ ||\\||\\
Network of soft CT fibers that surround the root of ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
the tooth. These fibers attach to the bone of the
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
,socket on one side and to the cementum of the root
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
on the other side [attach root to tooth socket].
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Gingiva: three functions ||\\||\\ ||\\||\\
1) Provides a tissue seal around cervical neck of tooth
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
2) Covers alveolar processes
||\\||\\ ||\\||\\ ||\\||\\
3) Holds tissue tight against tooth during mastication
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Cementum: function ||\\||\\
Anchors ends of PDL fibers to the tooth, helping||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
maintain tooth in the socket and protects the dentin ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
of the root.
||\\||\\ ||\\||\\
Periodontal Ligament: two functions ||\\||\\ ||\\||\\ ||\\||\\
,Suspends and maintains the tooth in its socket
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Alveolar Bone: two functions
||\\||\\ ||\\||\\ ||\\||\\
Surrounds and supports the roots of the tooth
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
Knowledge of the periodontium in health allows us ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
to understand what 3 things?
