Assessment of the Dentifrice Influence on Enamel Mature in the Aspect of Age and Caries Activity in 6–7, 12, 15 Year Old Schoolchildren

Abstract

It is possible to increase the effectiveness of preventive dental measures by a differentiated approach to the use of toothpastes [3]. The most intensive incorporation of calcium and fluorides into the composition of the hard tissues of teeth occurs during their formation and mineralization [4, 5]. At the end of the growth and mineralization of the teeth, the enamel and dentin of the teeth become less permeable to fluoride, but the need for them does not disappear. Also, a number of authors note that the need for ions with different caries activity may differ.
 The purpose of our study was to study the effectiveness of the use of toothpastes in 6–7, 12, 15-year-old schoolchildren with various caries activity. We examined 532 children, attending organized children's groups in Yekaterinburg. By a randomization procedure based on the method of random numbers, children were divided into groups according to the type of paste used: calcium-containing, fluorine-containing, combined use of calcium and fluorine-containing pastes, paste based on organosilicon glycerohydrogel. The toothpastes effectiveness was assessed by the change in enamel resistance by functional methods: electrometry and Enamel Resistance Test. The annual increase in caries was taken into account. It was found that calcium-containing toothpastes are most effective in the first month of use, then the effect of their use weakens. Fluoride toothpastes lead to a persistent but slow increase in enamel resistance. The combined use of calcium and fluoride toothpastes gives a quick and lasting effect. A paste based on organosilicon glycerohydrogel gives a persistent decrease in enamel electrometry, with the best results in the group of schoolchildren with high caries activity.
