Abstract

In order to examine the anticariogenic effect after fluoride varnish was applied to sound enamel and artificial caries enamel, anterior teeth of healthy cattle were used and divided into four groups such as group 1 (sound enamel), group 2 (application of fluoride varnish to sound enamel), group 3 (artificial caries enamel) and group 4 (application of fluoride varnish to artificial caries enamel). Remineralization on the surface of enamel and changes of crystalline structure after demineralization were observed by using a field emission scanning electron microscope (FE-SEM). Quantitative analysis of Ca and P was measured by using the energy dispersive X-ray spectrophotometer (EDS). The following conclusions were obtained: 1)Surface pattern of enamel was the roughest in group 3 due to the defects caused by porosity and microcracks. Group 4, group 1 and group 2 were followed in order; 2) It was found that pattern of crystalline structures in a group of application of fluoride varnish and a group of no application showed bigger change in artificial caries enamel than that in sound enamel. In other words, groups 4 and 1 showed a similar pattern; 3) The contents of Ca and P were higher in groups of application of fluoride varnish (group 2 and group 4) than in groups of no application of fluoride varnish (group 1 and group 3). Taken results of this study together, in the case of application of fluoride varnish, crystalline structure was changed by remineralization even in the sound enamel. In particular, porous structures showed a smooth and uniform pattern due to the recalcification in the artificial caries enamel. In addition, according to results of EDS analysis, the contents of Ca and P were increased and it had great anticariogenic effects which inhibit decalcification of sound enamel and artificial caries enamel.

정상법랑질과 인공우식법랑질에서 불소바니쉬 도포 후의 항우식 효과를 알아보기 위하여 건전한 소의 전치를 사용하였고, 네 군으로 분류하여 실험하였다. 법랑질 표면의 재광화 및 탈회 후 결정구조의 변화를 FE-SEM으로 관찰하였고, Ca과 P의 정량적 분석은 EDS를 사용하여 측정하였다. 그 결과 불소바니쉬 도포한 경우, 재석회화로 인하여 불규칙하고 매우 거친 표면과 다공성의 구조물이 평활하고 균일한 양상으로 나타났으며, Ca 및 P의 함량이 증가되어 정상법랑질과 인공우식법랑질의 항우식 효과를 크게 증진시키는 것으로 확인되었다.
