Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organised to a particular structure and function. [12] Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques. [13]
The ecological plaque hypothesis, a combination of the two previously mentioned hypotheses, suggests that there are certain species responsible for pathology, but are present in insufficient quantities to cause damage to a healthy individual. [13] Thus biofilm derived diseases are the result of an imbalance in the normal oral ecology. [14]
Tooth decay is caused by biofilm (dental plaque) lying on the teeth and maturing to become cariogenic (causing decay). Certain bacteria in the biofilm produce acids, primarily lactic acid, in the presence of fermentable carbohydrates such as sucrose, fructose, and glucose. [23] [24] [25]
Dental plaque, also known as dental biofilm, is a sticky, yellow film consisting of a wide range of bacteria that attaches to the tooth surfaces and can be visible around the gum line. It starts to reappear after the tooth surface has been cleaned, which is why regular brushing is encouraged. [1] A high-sugar diet encourages the formation of ...
Dental plaque and S. mutans is frequently exposed to "toxic compounds" from oral healthcare products, food additives, and tobacco. [citation needed] While S. mutans grows in the biofilm, cells maintain a balance of metabolism that involves production and detoxification.
Plaque is a biofilm composed of several different kinds of bacteria and their products that develop over the enamel on the pellicle. Plaque formation takes several days to weeks and will cause the surrounding environment to become acidic, if not removed.
Plaque is a biofilm on the surfaces of the teeth. This accumulation of microorganisms subject the teeth and gingival tissues to high concentrations of bacterial metabolites which results in dental disease. If not taken care of, via brushing or flossing, the plaque can turn into tartar (its hardened form) and lead to gingivitis or periodontal ...
Oral hygiene practices involve the mechanical removal of plaque from hard tissue surfaces [24] Cariogenic bacteria levels in the plaque determine whether caries will occur or not, therefore, effective removal of plaque is paramount. [25] The removal of plaque inhibits demineralisation of teeth, and increases opportunities for remineralization.
