what are the 4 gingival fibers?
- circumferential fibers
- dentogingival fibers
- alveologingival fibers
- dentoperiosteal fibers
what fibers are continuous around the neck of the tooth and help to maintain tooth position?
what fibers come from the cementum of the cervical region to the free gingiva and provide gingival support?
what fibers are from the alveolar crest into the free and attached gingiva and provide gingival support?
what fibers are from the cementum over the alveolar crest to blend with fibers of periosteum and provide gingival support?
what is the cuff like band of stratified squamous epithelium that is continuous with sulcular epithelium and completely circles the tooth?
what provides a seal at the base of the sulcus?
what is the function of the junctional epithelium?
provide a seal at the base of the sulcus
what is the junction of the attached gingiva and the alveolar mucosa called?
the muco gingival junction is the junction between the _____ _____ and the alveolar mucosa
the mucogingival junction is the junction between the attached gingiva and the ______ _____
t/f the anterior line of the mucogingival junction is flat
t/f the posterior line of the mucogingival junction is scalloped
false-flat in posterior
t/f the mucogingival junction is found on the maxillary lingual
t/f the mucogingival junction is found on all facial surfaces but only the lingual of the mandibular arch
what are the 6 periodontal ligament fibers?
- transseptal fibers
- alveolar crest fibers
- horizontal fibers
- oblique fibers
- apical fibers
- interradicular fibers
what periodontal fibers come from the cervical area of one tooth to the adjacent tooth to keep the teeth separated?
what perio fibers come from the alveolar crest to the cementum just below the CEJ and it helps to resist intrusive forces?
alveolar crest fibers
what perio fibers come from the cementum in the middle of each root to the adjacent bone and it helps to resist tipping?
what perio fibers go from the root above the apical fibers toward the occlusal and the help to resist vertical and strong forces?
what perio fibers go from the root apex to the adjacent bone and help to resist vertical forces?
what perio fibers go from the cementum between multirooted teeth into the bone and help to resist vertical and lateral forces?
what does healthy gingiva look like?
pink, knife edge, stippling, firm, No BOP, minimal probe depths, gingival margin right below enamel contour and no pus
what does diseased gingiva look like?
red, bluish, magenta, inflammation, shiny, smooth, rolled free gingiva, blunted flattend or bulbous papilla, soft spongy or fibrotic, pus, BOP, recession and col deepens,
