Ppt Mouthwash Dental Plaque A Microbial Biofilm Powerpoint 4. • dental plaque was the first biofilm to be studied in terms of both its microbial composition and its sensitivity to antimicrobial agents. • in the 17th century, antonie van leeuwenhoek pioneered the approach of studying biofilms by direct microscopic observation when he reported on the diversity and high numbers of animalcules present in scrapings taken from around human teeth. It begins by defining dental plaque as a host associated biofilm that adheres tenaciously to intraoral hard surfaces. plaque is classified as supragingival or subgingival based on its location relative to the gingival margin. the composition of plaque includes water, organic constituents like bacteria and carbohydrates, and inorganic. Dental plaque is a biofilm that forms on teeth. it consists of microbial communities embedded in an extracellular matrix. bacteria in plaque interact through quorum sensing, metabolic cooperation, and horizontal gene transfer. as plaque matures, physiological heterogeneity develops within the biofilm as bacteria occupy different microenvironments. 1 dental plaque (bacteria biofilm) dr.hussein al dabbagh. 2 the dental professional comes into contact with two of the most widespread of all human diseases dental caries and periodontal diseases. 3 dental plaque is defined clinically as a structured resilient yellow grayish substance that adheres tenaciously to the intraoral hard surface.

Dental plaque is a structurally and functionally organized biofilm. plaque forms in an ordered way and has a diverse microbial composition that, in health, remains relatively stable over time (microbial homeostasis). the predominant species from diseased sites are different from those found in healthy sites, although the putative pathogens can often be detected in low numbers at normal sites.
