It's your freakin gums! -Consists of Masticatory Mucosa
|

|
Term
|
Definition
1. Epithelium - thick keratinized strat squamous 2. Lamina Propria - numerous elongated, think CT papillae 3. Mucoperiosteum - direct attachment of lamina propria to underlying periosteum of alveolar process
|
|
|
Term
|
Definition
-Part of gingiva bordered coronally by the Free gingival Margin, apically by th Free Gingival Groove, along inner surface by Sulcular Epithelium and along outer surface by the oral cavity -Sulcus epithelium is thinner and not keratinized -Gingival sulcus ranges in depth from .5-3 mm (larger = perio disease)
|
|
|
Term
|
Definition
-Lies between Free Gingival Margin and Mucogingival Junction -Interdental Groove also found in this region (the divet between root eminances) -Healthy state shows Stippling
|
|
|
Term
|
Definition
-Consists of Interdental Papillae (wedge shaped gingiva that project to the contact points of adjacent teeth) -There is a central cavity/depression between facial and lingual aspects of the gingiva call the Col -The Col is thinner, non-keratinized and has inflammatory cells in the lamina propria (The col gets wider in post teeth)
|
|
|
Term
|
Definition
-Attaches the gingiva to the tooth with hemidesmosomes
-Begins at base of sulcus and consists of Junctional Epithelium and its associated lamina propria -Seal is permiable to water, high molecular weight substances and inflammatory cells
|
|
|
Term
|
Definition
-During tooth eruption, CT overlying reduced enamel ep. and underlying oral ep. begins to degenerate -Outer layer of REE and basal layer of Oral Ep proliferate and fuse together -Forms thick epithelial mass over over crown of tooth -Cells in middle of mass die -> makes corridor called Epithelial Cuff -Apical portion is future DGJ while rest becomes sulcular epithelium
|
|
|
Term
|
Definition
-As cusp tip erupts, reduced ameloblasts maintain connection to tooth via hemidesmosomes -> Primary Epithelial Attachment -Reduced ameloblasts undergoe morphologic change into squamous ep. cells -Outer REE cells change shape into basal cells -THUS, REE gives rise to Junctional Epithelium

| 5 Gingival Ligament Fiber Groups |
|
Definition
Everthing Coronal of the Alveolar Crest Fibers in the PDL is the Gingival Ligament
1. Dentogingival Group
2. Alveologingival Group 3. Circular Group 4. Dentoperiosteal Group 5. Transseptal Fiber Group
|
|
|
Term
|
Definition
-Most Numerous -Extend between cervical cementum to lamina propria of free and attached gingiva
|
|
|
Term
|
Definition
-Extend from alveolar crestal bone to lamina propria of free and attached gingiva
|
|
|
Term
|
Definition
-Band of collagen fibers that encirlce crown of tooth and intermingle with other fibers in free gingiva -This group helps hold the free gingiva against tooth surface
|
|
|
Term
|
Definition
-Run from cervical cementum to periosteum of alveolar crest where they extend to the vestibular surfaces of the alveolar bone |
|
|
Term
|
Definition
-Fibers originate on cervical cementum of one tooth and span alveolar crest to insert on cervical cementum of adjacent tooth -Take together, transseptal fibers constitute the Interdental Ligament and connect all the teeth in an arch -Have contractile abilities, can cause mesial drift -Throw occlusion out of whack is teeth are missing
