초록
The purpose of this study is to verify the effect of toothbrushing using a microcurrent toothbrush on the fluoride concentration on the enamel surface of teeth. Sixty samples were produced with sound cattle teeth and divided into control and experimental groups (ordinary and microcurrent toothbrush groups) to perform the brushing for four minutes using an automatic toothbrushing machine in a 2% NaF solution for each type of toothbrush. The specimen measured the microhardness of enamel surface after the pH cycling treatment, and the fluoride ratio of the enamel surface was identified by scanning electron microscope observation and EDS analysis. The microhardness of the enamel surface of the microcurrent toothbrush group was higher after brushing (279.64) than before brushing (267.74) (p=0.008). In scanning electron microscopic observation, it was confirmed that the enamel surface after brushing with a microcurrent toothbrush appeared a slight irregular spherical crystals, forming fluoroapatite. According to the EDS analysis of the scanning electron microscopy, the fluoride content of the enamel surface was 1.76% in the control group, while 22.29% in the microcurrent toothbrush group. In sum, it has been found that toothbrushing using microcurrent toothbrushes is effective in preventing tooth decay by increasing the formation of fluoroapatite in the enamel.
