The document discusses the role of carbohydrates in dental caries (tooth decay). It states that fermentable carbohydrates like glucose, fructose, and sucrose are easily fermented by bacteria like Streptococcus mutans in dental plaque, producing acids that demineralize tooth enamel and lead to cavities. The rate of decay depends on the type of carbohydrate, frequency of consumption, and how long sugars remain stuck to teeth. It also discusses factors like microorganisms, acids, dental plaque, and tooth structure that influence the caries process according to Miller's chemico-parasitic theory.
