Dental caries result when the demineralization rate is faster than the remineralization, producing net mineral loss, which occurs when there is an ecologic shift within the dental biofilm from a balanced population of microorganisms to a population that produces acids and can survive in an acid environment.
As of 2005 surveys conducted by the National Institute of Dental and Craniofacial Research in the USA between 1986 and 1987 [29] and by the Center of Disease Control between 1999 and 2004 [28] are the only national sources of data concerning the prevalence of dental fluorosis. Before the 1999-2004 study was published, CDC published an interim ...
This index is based on in-field clinical examination of individuals by using a probe, mirror and cotton rolls, and simply counts the number of decayed, missing (due to caries only) and restored teeth. Another version proposed in 1931 [1] counts each affected surface, yielding a decayed, missing, and filled surfaces (DMFS) index. Statistics are ...
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 ...
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess , and the second most common is a periodontal abscess . In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.

Dental caries (cavities), described as "tooth decay", is an infectious disease which damages the structures of teeth. [43] The disease can lead to pain , tooth loss , and infection. Dental caries has a long history, with evidence showing the disease was present in the Bronze , Iron , and Middle ages but also prior to the neolithic period. [ 44 ]
