• Persons that like carbohydrate foods and snack frequently on sticky, sugary foods and do not often eat dairy foods.
• People who do not use toothpaste with fluoride brush regularly and correctly and do not looking for regularly dental care.
• With children to approximately 10 years, if nutrition is inadequate, the enamel formation could be affected, this causes pits and areas of roughness which can be more compliantable to dental caries.
• Infants and children’s who are put to sleep with dummy teats dipped in sugar or with bottles containing fluids other than water.
• Peoples who suffer from eating deranges such as bulimia, anorexia , where throwing out is induced so causing not normal oral acid - an environment for decompose.
• A lot of old people are at risk due to higher slant of chronic sickness and multiple drug use, not normal oral hygiene and lack of food variety, all of which leading to very poor dental health.
• People with diabetes are at a very big risk, potential causes include increased salivary glucose levels in not proper controlled diabetes, decreased salivary flow and dry mouth.
• People living in a countries without a fluoridated water supply. Fluoride decreases the caries value due to its effect on the tooth surface - it reverses the demineralising effect of acids produced by plaque.
Caries is the result of complex number of interactions involving the individual (nutrition, genetics, behaviour, race, and age), plaque bacteria, saliva flow and composition and the environment.
Food has been shown to be very important element of the environment that can be 'at risk' and so cause dental caries as the following information will show:
• The children of the world's most remote community Tristan da Cunha, Southern Atlantic, were notably free of caries in 1937 when their diet were mainly potatoes, fish, sea birds and eggs, some meat, mutton, apples and berries. But, since they began to adopt the modern food and life style they start to have caries.
• When use of refined carbohydrates and sugar were rationed during World War 2, snacking decreased and so did the increase rate of caries. After war the caries rate increase as sugar restrictions were lifted. The measurable differences were most meaningful in England, Norway and Japan.
