The arrest of dental caries appeared to have occurred as the result of their having been restricted to the low-carbohydrate high-fat type of diet now generally used by diabetic patients. Dental caries progresses with age, and the effects of sugars on the dentition are lifelong. High intakes of carbohydrate may facilitate the colonization of bifidobacteria and lactobacilli in the gut and thus reduce the risk of acute infective gastrointestinal illnesses. This type of diet does not seem to have been further studied as a means of controlling dental caries, and … With respect to dental caries, there are certain trace elements that may aid in the progression of dental caries, whereas there are some trace elements which may stop the development of dental caries. 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. Dental caries, also known as tooth decay, is one of the most common oral infections in children ().It is a destructive process that causes decalcification of tooth enamel and subsequently leads to continued breakdown of enamel and dentin ().If left untreated, some pathogens or pathobionts in the oral microbiota can penetrate the enamel and dentin to reach the pulp, which leads … •introduction •definition •remineralisation and demineralisation •classification of dental caries •zones of enamel caries •zones of dental caries •microbiology of the dental caries •theories of dental caries contents i’m ready… dr. ram 4. Taking into consideration that the mechanisms might be different for both diseases, fermentable carbohydrates are the most relevant common dietary risk factors for caries and periodontal diseases (Moynihan & Petersen 2004). Dental caries is a transmissible bacterial disease caused primarily by the bacteria listed above feeding on the carbohydrates taken into the mouths of humans. Actinomyces spp. 11, 12 The so‐called cavity or hole in the tooth is the end‐point. Obesity is an important risk factor for gallstones. dental caries - an irreversible microbial process…. dr. ram 3. An individual can be in the "high-risk" or "low-risk"category for development of dental caries. The incidence of dental caries … Dental caries is one of the most common contagious diseases found among human beings. The presence of cariogenic bacteria and fermentable carbohydrates are prerequisites for dental caries, with bacterial metabolic activity resulting in the production of acid that can demineralize dental hard tissues.1 Pitts NB, Zero DT, Marsh PD, Ekstrand K, Weintraub JA, Ramos-Gomez F, Tagami J, Twetman S, Tsakos G, Ismail A. Even low levels of caries in childhood are of significance to levels of caries throughout the life-course. Neutral pH environments and excess carbohydrate availability could promote urease expression of Actinomyces in ... such as A. naeslundii, A. viscosus, and A. odontolyticus may be involved in the etiopathogenesis of dental caries and periodontal disease. Diet plays an important role in the advancement of dental caries. About 50 years back dietary sugars were Dental caries. Irrespective of their role in oral health, these trace elements … A dynamic relation exists between sugars and oral health. INTRODUCTION. Dental caries. All of the following factors are low-risk factors in the development of dental caries for adults except one.
