Masticatory mucosa includes free and attached gingiva, it is thick, dense *designed to withstand trama ** Keratinized Lining mucosa thin, free moving, tears easily **NON-Karetinized-smooth Red in color b/c of a lot of capillaries Includes: soft palate, vestuble (averolar mucosa & buccal mucosa), floor of mouth, inside cheecks/lips (labial mucosa) Gingival sulcus space b/w free gingiva & tooth Free gingiva between free gingival margin & free gingival groove found: sulcus Free ginigval groove seperates FREE and attached ginigiva found bottom of gingival sulcus Attached gingiva attached to underlying bone lies between freegingiva & aveolar mucosa mucogingival junction seperates attached gingiva from aveolar mucosa junctional epithelium how tissue attaches to tooth ends at gingival sulcus found:base of sulcus Rete pegs causes stippling connects to epithelium to underlying connective tissue-> makes stippling Interdental groove vertical depression fx: allows food to spill into vestible COL found: tip of interdental papilla-> just below contact area site of gingival inflamation Gingival fibers there are 3 -group1 -group2 -group3 group1 up cementum up to gingival margin -dentogingival fiber group 2 out/horizonally -goes straight out makes free gingival root group 3 down & comes over aveolar bone/crest Transseptal -connects tissue of adjacent teeth connects gingival between teeth Circular holds tissue around tooth-like a neck tie -fiber to fiber connection Peridontal ligaments there are 5 aveolar bone, horizontal group, oblique group, apical group, interradicular group aveolar bone -LOCATION crest bone to cementum horizontal group -DIRECTION goes horizontal from cementum to aveolar bone oblique group -DIRECTION ***** MOST NUMEROUS runs diagonally cementum to bone apical group -LOCATION apically from cementum to bone interradicular group -LOCATION multi-rooted teeth *** molars & premolars cellular apical 1/3 acellular middle 1/3 Aveolar bone 3 layers: cortical bone, trabecular bone,cribiform plate cortical bone buccal & lingual surface trabecular bone fx: add/had bone marrow cribiform plate aveolar bone ** under pressure makes more called: Bundle Bone **** forms in Avolas (tooth socket)----KNOW lamina dura-radio-pake(white) Periodontal disease gingivitis,periodontitis Gingivitis ** Pseudo pocket-inflamed gums immflamation in gums Periodontitis lossof bone level Layers added to cribiform plate/bone bundle bone Osseous apposition new bone forming Osseous resorption loss of bone
