Metabolism of xylitol in dental plaque

European Journal of Oral Sciences, 1985
Abstract – It has been reported previously that xylitol added to glucose used to challenge dental plaque in vivo caused a reduced acid formation. The aim of the present study was to approach the mechanism by which xylitol may affect glucose catabolism in plaque bacteria.

Saliva and Dental Plaque

Advances in Dental Research, 2000
Dental plaque is being redefined as oral biofilm. Diverse overlapping microbial consortia are present on all oral tissues. Biofilms are structured, displaying features like channels and projections. Constituent species switch back and forth between sessile and planktonic phases. Saliva is the medium for planktonic suspension.

Nature and Composition of Dental Plaque

Nature, 1961
ALTHOUGH dental plaque is often mentioned in dental literature, its chemical composition has received little attention. Current literature frequently refers to “dentobacterial plaque” with the implication that it consists principally of bacteria. Manly1, however, brushed teeth with a detergent prior to the collection of a film, which he called “brown ...

Dental Plaque Morphology and Induction

Proceedings, annual meeting, Electron Microscopy Society of America, 1972
Investigators consider plaque to be an early stage of calculus. The plaque matrix may contain a modified protein on which the calculus crystals may form. Another view is that lowering of the pH to 5 or 6 may cause a protein to precipitate on which the calcium crystals deposit.

Dental Plaque and Oral Health

Nature, 1971
Oral diseases in man, such as periodon-titis and dental caries, are not caused by single pathogenic organisms but appear to be the result of the complex biological interactions of the various organisms of which dental plaque is composed.

Wet Weights of Dental Plaques

Journal of Dental Research, 1978
A method for weighing samples of plaque using a weighing assembly comprising a sample-bearing boat, held in a closed capsule to avoid moisture loss to room or balance environment is described. The system described is an objective device for measuring, by wet weight the amounts of plaque accumulating under various conditions of oral hygiene.

Immunoglobulins in human dental plaque

Journal of Periodontal Research, 1979
Immunoglobulins have been found previously in human gingiva, gingival fluid, serum and smeas of dental plaque. In the present study their presence and distribution in situ have been studied by immunofluorescence on the approximal surfaces of childen's teeth extracted due to caries or for orthodontic reasons. There wee also preliminary investigations of

Activation of complement by dental plaque

Journal of Periodontal Research, 1980
Dental plaque samples and oral bacterial cells consumed complement (C) in human serum. No significant difference was found between the C binding ability of dental plaque samples from patients with periodontal disease and those of samples from healthy individuals.

Carbohydrates in Pooled Dental Plaque

Caries Research, 1972
Dental plaque was collected from approximately 3,500 schoolchildren, and immediately pooled and frozen. The lyophilized plaque was processed in several batches as follows:After an aqueous extraction the water-insoluble portion was further extracted with 1 N KOH.
