Why sucrose is called as arch criminal?
Newbrun (1967) called sucrose the “arch criminal of dental caries” because only sucrose serves as a substrate for extracellular polysacharide synthesis of certain microbial organisms implicated in dental caries.
What are cariogenic bacteria?
Dental caries is a disease in which bacteria ferment carbohydrates, which produces acids and breaks down tooth mineral. 1,2. These cariogenic bacteria are acidogenic (acid-forming) and aciduric (tolerate a highly acidic environment), and include Streptococcus mutans, Streptococcus sobrinus, and lactobacilli.
What sugars are cariogenic?
Sugar is the principal cause of the most common disease in industrialised countries, dental caries. The sugars implicated in dental caries, in decreasing order of cariogenicity, are sucrose, glucose, and fructose; brown sugars are as cariogenic as white.
Which sugar is the most cariogenic?
Sucrose is considered the most cariogenic dietary carbohydrate, because it is fermentable, and also serves as a substrate for the synthesis of extracellular (EPS) and intracellular (IPS) polysaccharides in dental plaque (Newbrun, 1967; Bowen, 2002).
What is a cariogenic in dentistry?
Cariogenic bacteria live in biofilm and attack dental enamel by converting sugar and starch into acids that dissolve out calcium from the enamel. This process can cause caries. The dissolution of calcium increases the concentration of calcium locally, creating an environment that is hostile to bacterial life.
Are fruits cariogenic?
Among the dietary factors, the frequency of fruit consumption was associated with higher odds of caries experience (odds ratio: 1.52, 95% confidence intervals: 1.05, 2.21). Conclusions: Exposure to a high level of fruit consumption was suggestive of increased caries risk.
What is a Stephan curve?
The Stephan Curve is a graph that shows what happens after the consumption of sugar in relation to dental caries. After sugar intake, demineralisation of the tooth surfaces takes place due to the drop in pH as the bacteria in the mouth convert the sugar to acid.
Which carbohydrate is the least cariogenic?
Sugars can be readily metabolized by many bacteria involved in dental biofilm formation, generating acid byproducts that can lead to demineralization of the tooth structure. Lactose (milk sugar) has been shown to be less acidogenic than other sugars and less cariogenic, based on animal studies [8].
What acids do cariogenic bacteria produce?
Lactic acid or lactate is produced by cariogenic bacteria within dental plaque attached to the surface of a tooth. The cariogenic bacteria break down sucrose to glucose and fructose. Glucose and fructose are then broken down to produce energy (ATP) for the cariogenic bacteia.
What is fluoride in dentistry?
Fluoride is a naturally occurring mineral used in many dental products to strengthen tooth enamel and prevent cavities. It’s also added to the local water supplies in many American cities.
Are potatoes cariogenic?
Low cariogenic foods include: white bread with chocolate and sweet spreads and whole grains, whole wheat bread, tortillas, wholemeal pasta, cooked starchy vegetables (such as corn, potatoes, yams, peas, carrots, beans), acidic fruits (such as mango and berries), soup and meat or cheese sandwiches.
What foods are considered to be cariogenic?
Cariogenic Foods Can Promote Development of Tooth Decay Examples of cariogenic foods and beverages include: Sugary and starchy foods such as bread, rice, noodles, crackers, cakes, sweetened cereals, and hard and chewy candies; Sticky foods such as dried fruits, fruit snacks, cookies, and chewy candies (toffee);
