title: [Significance of plaques for the etiology of caries and marginal periodontopathies (author's transl)].
abstract: The genesis of dental caries and marginal periodontopathies has a conclusive connection with dento-gingival plaque. Plaque is a constantly regenerating accumulation of salivary constituents and especially of various oral micoorganisms. Microbial decomposition of sugars from the food produces acids from fermentation which lead to local demineralization of the teeth and carious destruction. Antigenic plaque substances cause immunological reactions. With persistent bad oral hygiene, a gingivitis may develop into a progressive periodontitis with deepened gingival pockets.
