Dental cavity, also known as tooth decay, [a] is the breakdown of teeth due to acids produced by bacteria. [6] The resulting cavities may be a number of different colors, from yellow to black. [ 1 ] Symptoms may include pain and difficulty eating.
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] A clean tooth surface would immediately be colonised by salivary pellicles, which acts as an ...
Bacteria occupy the ecological niche provided by both the tooth surface and mucosal epithelium. [ 7 ] [ 8 ] Factors of note that have been found to affect the microbial colonization of the oral cavity include the pH, oxygen concentration and its availability at specific oral surfaces, mechanical forces acting upon oral surfaces, salivary and ...
Different areas of the oral cavity present different ecological niches, and each species has specific properties for colonizing different oral sites. S. mutans is most prevalent on the pits and fissures, constituting 39% of the total streptococci in the oral cavity. Fewer S. mutans bacteria are found on the buccal surface (2–9%). [7]
The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans, Porphyromonas gingivalis, and Staphylococcus. [15] S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut ...
Teeth, saliva, and oral tissues are the major components of the oral environment in which the oral microbiome resides. Like most environments, some oral environments, such as teeth and saliva, are abiotic (non-living), and some are living, such as the host immune system or host mouth mucosal tissues- including gums, cheek ("buccal") and tongue (when present).
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
The high mineral content of enamel, which makes this tissue the hardest in the human body, also makes it demineralize in a process that often occurs as dental caries, otherwise known as cavities. [13] Demineralization occurs for several reasons, but the most important cause of tooth decay is the ingestion of fermentable carbohydrates.
