Abstract
We researched and examined the influence on tooth enamel when infants drink ionized drinks with pH of 5.5, 4.2 and 3.8 using the mouse strain C 57 BL/6. The mice teeth showed no morphological abnormality same as the control group (drinking purified water) when the mice ate general solid food and drank the ionized drinks (pH 5.5). On the other hand, the mice teeth showed severe dental attrition with pulp exposure on lower jaw when mice drank pH 4.2 and pH 3.8 ionized drinks. Furthermore the mice drank various types of drinks, ate a high sucrose diet in a powdery state and infected Streptococcus mutans showed dental caries advanced to dentin on 1 st or 2nd molar in all experimental group including the control group. Particularly ionized drinks contained high rates of carbohydrates with pH of 4.3 showed the highest caries score and there were no significant differences of caries scores on the other drinks.We suggested that taking ionized drinks with considerable frequency damages the dental enamel and dental caries is advanced by low pH ionized drink including higher carbohydrates while eating a high sucrose diet.
