2003 Oct. 78 (4):881S-92S. Streptococcus mutans species are a group of related bacteria that grow in plaque and can cause caries. 11, … Studies have confirmed the direct relation between intake of dietary sugars and dental caries across the life span. 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. . Gazzani G, Daglia M, Papetti A. 12, No. The most important cause of dental caries is the frequency of intake of fermentable carbohydrates, which supply sub­strate to the caries-producing oral bacteria. 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. The incidence of dental caries is influenced by a number of factors. PDF | On Mar 14, 2012, Arezoo Tahmourespour published Probiotics and the Reduction of Dental Caries Risk | Find, read and cite all the research you need on ResearchGate Food components with anticaries activity. 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. 1, 1710953. Touger-Decker R, van Loveren C. Sugars and dental caries. Integrated hypothesis of dental caries and periodontal diseases. Dental caries. Host – The first requirement for dental caries is a susceptible host – a mouth with teeth. Regardless of any other factor, caries cannot occur in the absence of bacteria. It is progressive and cumulative, and becomes more complex with time. Plaque is, at first, a soft, thin film of bacteria, mucin, dead epithelial cells, and food debris that develops on the tooth surface within about 24 hours after the tooth is cleaned. Dental caries Dental caries - Classification and external resources Destruction of a tooth by cervical decay from dental caries. Carbohydrate: it provides the basis of life for bacteria. There are multiple mechanisms by which fluoride works:2 Dental caries remains the most common chronic disease of childhood in the United States. Am J Clin Nutr. Food – Food, specifically carbohydrate-containing food, is the second requirement for dental caries. Tanaka K, Miyake Y, Sasaki S. Intake of dairy products and the prevalence of dental caries in young children. 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. 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 ... nurse or pharmacist before following any medical regimen to see if it is safe and effective for you. 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. dental caries varied from 30 to 97.2%, ... mechanisms of caries inhibition by laser remain unclear. Dental caries remains the most prevalent pathological condition worldwide, with minimal change in prevalence and incidence over the last two decades. Several modifying risk factors and protective factors influence the dental caries process. Dental caries results when 3 factors come together: 1. 1 INTRODUCTION. (2020). This type of decay is also known as root decay. Dental caries can be referred to as a process of enamel and dentine demineralisation, which is caused by organic acids produced in the bacterial fermentation of sugars derived from the diet. In the mouth, these changes over time in response to a challenge (usually a cariogenic food) are known as Stephan responses or Stephan curves. Both caries and periodontal disease are, for the most part, acquired and preventable disturbances of the teeth and jaws. J Dent. Dental Caries Causes. 9.1. Dental caries is a multifactorial disease that involves an interaction between teeth, saliva and oral microbiota, as the individual’s own risk factors, and diet and oral hygiene, as the main external factors. 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. 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. Dental Caries (n.). Plaque is, at first, a soft, thin film of bacteria, mucin, dead epithelial cells, and food debris that develops on the tooth surface within about 24 hours after the tooth is cleaned. Other chapters of this book are devoted to a more in-depth discussion of the cause, prevention, and management of dental caries (see Chapters 10, 17, 18, and 19) and periodontal disturbances (see Chapters 11 and 20). Abstract Dental caries is the single most common, chronic oral disease of childhood (Boyce et al., 2010). Dental caries are also called cavities. Protective factors which ... Fluoride in drinking water and in fluoride‐containing products reduces tooth decay via these mechanisms. Dental caries is a biofilm-dependent oral disease, and fermentable dietary carbohydrates are the key environmental factors involved in its initiation and development. However, among the carbohydrates, Poor oral hygiene: lack of dental care promotes bacterial growth, proliferation and the formation of plaque. Dental caries is the most common oral disease. One very disturbing evidence is that the prevalence of untreated caries lesion remained stable from 1990 to 2015 [] and the peak of the disease is among very young children, aging 1–4 years old [].Dental caries is a dynamic, multifactorial, non-communicable and biofilm-mediated disease. Dental caries, also known as tooth decay or cavity, is a disease wherein bacterial processes damage hard tooth structure (enamel, dentin, and cementum). 2. The bacteriological aetiology of dental caries promotes the use of antibiotics or antimicrobial agents to prevent this type of oral infectious disease. 20. 1 The evidence is mounting that dental caries is a growing concern in the ageing populations. Dental caries is a bacterially based disease that progresses when acid produced by ... (mutans streptococci and lactobacilli), salivary dysfunction, and dietary carbohydrates are related to caries progression. 1. Microbial agent Dental caries is a bacterial disease. 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. Dental caries is a transmissible bacterial disease caused primarily by the bacteria listed above feeding on the carbohydrates taken into the mouths of humans. Acidogenic bacteria in dental plaque rapidly metabolize fermentable carbohydrates, producing acidic end products. Dental Caries). The bacteria mix with carbohydrates from foods and create acids. 38(7):579-83. . salivary flow or replace fermentable carbohydrates with non-fermentable alternatives may be more promising. LASERS EFFECTS ON ENAMEL FOR CARIES PREVENTION 867 could promote changes in the shape and size of hydroxyapatite crystals and loss of prismatic structure [27, 30, 35]. 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. 21. Fermentable carbohydrates: a key factor in the caries process. Journal of Oral Microbiology: Vol. Prevention of Dental Caries As regards the etiology of dental caries, it is still theoretical. The acids break down areas of enamel, which covers the outside of a tooth. The bacteriological aetiology of dental caries promotes the use of antibiotics or antimicrobial agents to prevent this type of oral infectious disease. •Dental caries is a transmissible infectious disease as cariogenic bacteria usually passed along from mother to infant. Antibiotics have been developed for more than 80 years since Fleming discovered penicillin in 1928, and systemic antibiotics have been used to treat dental caries for a long time. However, dental caries onset and activity are, in fact, much more complex, as not all persons with teeth, biofilm, and who are consuming carbohydrates will have caries over time. Caries is caused by acids produced by bacteria in dental plaque. Streptococcus mutans species are a group of related bacteria that grow in plaque and can cause caries. Untreated caries lesions in deciduous teeth affect more than 570 million children around the world. 8 The pH of dental plaque under resting conditions (i.e., when no food or drink has been consumed), is fairly constant. however,• Proteolytic bacteria are rare in oral cavity• No explanation for role of carbohydrates, acid, etc in dental caries• Carious lesions cannot be reproduced in vitro by the proteolytic mechanisms• Gnotobiotic studies: caries can occur in absence of proteolytic organisms.• Enamel is largely inorganic. The most accepted theory is Miller's chemico-parasitic or acidogenic theory on which most of the preventive measures are based. Dental caries is the most common oral disease.
