Abstract
There is no adverse opinion on the anticariogenic effect of fluoride, so glass ionomer restoration which release the fluoride is recommended fer child patient. To study the anticariogenic effect of initial carious lesion of fluoride released from adjacent glass ionomer restoration, the in situ model was constructed. A microhardness test, polarized scope investigation and electron probe microanalysis was done for analyzing the distribution of fluoride which was precipitated from glass ionomer restoration to the enamel caries lesion. Fuji IX, the conventional glass ionomer, was used for experimental group and Z-100, composite resin that fluoride was not contained, was used for control group. On the microhardness test, the remineralization was accelerated by fluoride. And on the polarized investigation, the size of caries lesion was reduced in the oral cavity and that phenomenon was accelerated by fluoride, too. Electron probe microanalysis shows that the remineralization was accelerated by fluoride and the fluoride concentration on subsurface area was increased. It maybe that the subsurface area was critical to anticariogenic effect. In summary of these result, initial caries lesion can be remineralized in the oral cavity and that phenomenon can be accelerated by fluoride. The subsurface area of caries lesion was a major part of defense to cariogenic invasion and to conserve the subsurface area, the surface of lesion body have to conserved.
불소의 항우식 작용에 대해서는 논란의 여지가 없으며, 소아치과 임상에서 다량의 불소를 함유하고 있는 글라스 아이오노머는 이러한 이유로 선호되고 있다. 유리된 불소가 인접 법랑질의 항우식 효과에 미치는 영향을 평가하기 위하여 in situ 모형을 제작하고, 불소의 침투 경로와 범위 그리고 재광화 정도를 평가하기 위하여 미세 경도 측정법, 편광 현미경 관찰 및 전자 탐침 미소 분석 (EPMA, Electron Probe Micro-Analysis)을 시행하였다. 전통적인 글라스 아이오노머인 Fuji
