Zusammenfassung: | Clinical, histopathological and bacteriological aspects of chronic desquamative gingivitis were studied in afflicted patients. Clinically, there was a deteriorative stage in which the gingiva showed marked epithelial exfoliation with a glossy erythematous appearance, and a remissive stage in which these features abated, the two stages showing peri odic alteration. Histopathologically, the parakeratinized epithelium was thinned, with short or absent rete pegs, and inflammatory cell infiltration was evident in epithelial intercellular spaces; extensive lymphocyte infiltration was seen beneath the epithelium. There was also hydropic change in the basal cell layer and micro-bulla formation beneath the epithelium. Electron microscopically, amorphous substances were observed in the space created by separation of basal cells and the basal lamina. The basal lamina showed tearing, and desmosomes were decreased in number. Bacteriologically, there was no correlation between the deteriorativeand remissive stages with regard to bacterial counts, proportional distribution of gram- positive and gram-negative bacteria, or colony counts of bacteria from saliva, gingival crevicular fluid, tongue plaque, and periodontal pockets. |
