1
Define pathogenesis
the sequence of events that occur during the development of a disease or abnormal condition
2
Define periodontal disease
inflammation of the periodontium
3
Contrast periodontal disease with periodontitis
periodontitis is one of the two categories of periodontal disease; the other is gingivitis
4
Define periodontisis
bacterial infection of all parts of the periodontium including the gingiva, periodontal ligament, bone, and cementum
5
Define gingivitis
bacterial infection that is confined to the gingiva; type of periodontal disease characterized by changes in the color, contour, and consistency of gingival tissues
6
Periodontium, clinical and histologic, in Health
Pink; gingival margin - scalloped, above (coronal to) CEJ; papillae - firm, occupy embrasures apical to contact areas; no BOP; probing depths from 1-3 mm.
JE firmly attached by hemidesmosomes to enamel coronal to CEJ; epi-conn tissue jct - no epithelial ridges; gingival fibers intact; alveolar bone intact and 2-3 mm below (apical to) JE; PDL fibers intact; cementum is normal
7
Periodontium, clinical and histologic, in Gingivitis
Red or reddish blue; GM - swollen and loses knife-edge and even more coronal to CEJ; papillae - bulbous and swollen; BOP on gentle probing; probing depths 3+ mm and NO apical migration of junctional epithelium.
Still attached by hemidesmosomes; epi-conn tissue jct - extends epithelial ridges down into the connective tissue (wavy) from destruction of gingival fibers; alveolar bone intact; PDL fibers intact; cementum is normal ** REVERSIBLE
8
Periodontium, clinical and histologic, in Periodontitis
spongy tissue (edematous) bluish- or purplish red with smooth, shiny appearance OR light pink with leathery consistency (fibrotic tissue); GM - swollen or fibrotic, no knife-edge; recession; Interdental papillae -
9
Acute gingivitis vs Chronic gingivitis
lasts for a short period of time vs for months or years; some fluid in gingival connective tissues, swollen and red gingiva vs formation of new collagen fibers, enlarged and leathery tissues, concealed redness from fibrosis
