Dental Plaque Morphology and Induction
Proceedings, annual meeting, Electron Microscopy Society of America, 1972Investigators 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.

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.

Immunoglobulins in human dental plaque
Journal of Periodontal Research, 1979Immunoglobulins 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, 1980Dental 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.

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.

Carbohydrates in Pooled Dental Plaque
Caries Research, 1972Dental 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.

Publisher Summary This chapter discusses the dental plaque. The dental plaque is complex and contains a wide variety of micro-organisms, including those with little or no specific affinity for the true host oral surfaces but colonizing on the pre-existing flora.

Mechanisms of Dental Plaque Formation
Advances in Dental Research, 1994Much effort has been placed on elucidating the diverse mechanisms of microbial adhesion to tooth surfaces. Both specific and non-specific types of adhesion have been envisaged. Pioneer colonizers represent a selected part of the oral microflora, and it has been assumed that specific adhesinreceptor interactions between the microbial surface and the ...

Relationship Between Dental Plaque Indices and Bacteria in Dental Plaque and Those in Saliva
Journal of Dental Research, 1987A variety of indices has been developed for the quantitation of dental plaque. The aim of this study was to determine the correlation between the Löe plaque index and the number of bacteria on the same tooth. Furthermore, the effect of plaque accumulation on the salivary counts of some dental plaque organisms was estimated.
