carbohydrates promote dental caries by which of the following mechanisms?
These factors are: Bacteria: they decompose carbohydrates and produce acidic metabolites that attack tooth enamel. Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formationIf left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp. Dental caries, also known as tooth decay or cavity, is a disease wherein bacterial processes damage hard tooth structure (enamel, dentin, and cementum). Foods containing sugars or starch may be easily broken down by a-amylase and bacteria in the mouth and can produce acid which increases the risk of caries. It is progressive and cumulative, and becomes more complex with time. 20. 1 The evidence is mounting that dental caries is a growing concern in the ageing populations. Dental caries (tooth decay) is a multifactorial process that is caused by several factors. Context Dental decay is the most common chronic disease of children and it disproportionately affects those living in poverty, but the reasons for this are not clear.Passive smoking may be a modifiable risk factor for dental caries. Studies have confirmed the direct relation between intake of dietary sugars and dental caries across the life span. Microbial agent Dental caries is a bacterial disease. Dental caries remains the most common chronic disease of childhood in the United States. However, among the carbohydrates, Prevention of Dental Caries As regards the etiology of dental caries, it is still theoretical. There are multiple mechanisms by which fluoride works:2 carbohydrates and dental caries in children and adolescents; a greater fre- quency of carbohydrate intake, especially sucrose, leads to a greater risk of dental caries. Host – The first requirement for dental caries is a susceptible host – a mouth with teeth. Several modifying risk factors and protective factors influence the dental caries process. Many factors in addition to sugars affect the caries process, including the form of food or fluid, the duration of exposure, nutrient composition, sequence of eating, salivary flow, presence of buffers, and oral hygiene. 2. Poor oral hygiene: lack of dental care promotes bacterial growth, proliferation and the formation of plaque. Tanaka K, Miyake Y, Sasaki S. Intake of dairy products and the prevalence of dental caries in young children. Caries in Prehistoric Man 3000-750 BC3 Since teeth can survive in dry burial sites for thousand of years and since no caries like lesions have been produced in cadavers, reliable data on occurrence of dental caries in ancient population are available. Dental caries are also called cavities. Dental caries Dental caries - Classification and external resources Destruction of a tooth by cervical decay from dental caries. Dental caries. 1, 1710953. salivary ﬂow or replace fermentable carbohydrates with non-fermentable alternatives may be more promising. Key words: Diet, dental plaque, microbiology, dental caries, S. mutans, sugar, starch INTRODUCTION There have been numerous reviews on both the micro-bial aetiology of caries and on the dietary factors associated with caries. Fluoride is the Key to Prevention of Tooth Decay Fluoride works to reduce the prevalence and severity of dental caries that requires restorative dental care, in preeruptive, posteruptive, systemic, and topical situations. The bacteriological aetiology of dental caries promotes the use of antibiotics or antimicrobial agents to prevent this type of oral infectious disease. mechanisms of dental caries Nov 17, 2020 Posted By Edgar Rice Burroughs Ltd TEXT ID 627be99c Online PDF Ebook Epub Library which oftenleads to cavitationshafers textbook of oral pathology 6th edition this review investigates the mechanisms of bioactive glass on the management of dental caries The acids break down areas of enamel, which covers the outside of a tooth. Carbohydrate: it provides the basis of life for bacteria. Numerous reports have shown that dental sealants are safe and highly effective in preventing pit and fissure caries in primary and permanent teeth, reducing dental caries by over 70% after 2- to 3-year follow-up. 12, No. This type of decay is also known as root decay.
