Do you think children with low ph have high risk in dental caries? And what do you think will happen to the child if he/she has high ph level?what...

In 1950, it was clearly demonstrated, by animal conducted studies, the occurrence of cavities process is caused by bacteria which,in their absence, do not appear,whatever the type of food ingested would be. Rats, without oral bacteria, have not made cavities, although their food was containing sucrose, while rats with oral bacteria have made cavities , receiving the same type of food.

Research has shown that bacteria feed on sugars and produce acids present in food, their metabolic byproducts. These acids dissolve tooth enamel and start the evolution cavities process. The speed of the development of cavity processes differs from one person to another, depending on many factors.

Bacteria in dental plaque need a tiny amount of carbohydrates to produce acids.Raisins, crackers or white bread, which are in the oral cavity in sufficient quantity to produce acids, for a time equal to or even higher than milk chocolate or caramels, becoming more sticky than they. Sticky feature is different in the oral cavity compared tactile sensation.They say that chocolate and caramels contain soluble sugars and are quickly removed by saliva than other foods such as bread, which is not easily removed by saliva and thereby adhere to a longer period of teeth.

Moreover, studies by which was measured bacterial plaque pH, showed that drinks that give the feeling that leaving the mouth quickly, maintain a pH level, similar to that of many solid foods, for a long period of time .

In elderly people, blood pH is closer to the lower end (the blood becomes more acidic), and in children is more increased, which favors the growth phenomena. The pH is low in the morning, because the respiratory center excitability decreases during the night and carbon dioxide accumulates. He also falls in physical effort by an excess of lactic acid formation, as well as during intestinal digestion. Increased during gastric digestion because of loss of H + in gastric juice. PH deviations outside the limits mentioned cause serious disturbances and even death
