Ppt Mouthwash Dental Plaque A Microbial Biofilm Powerpoint 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. 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.
