Abstract

The purpose of this study was to evaluate the efficacy of gargle and toothpaste containing low concentration with sodium fluoride on the remineralization through the surface microhardness and mineral content in enamel. After 4 weeks-application, the enamel surface was measured using microhardness tester and the calcium (Ca) and phosphorous (P) concentration of mineral content by electron probe microanalyzer (EPMA) analysis. By combining fluoridated gargle with toothpaste, a remineralized enamel resulted in significantly significant differences among the four groups (p<0.05). The Ca change treated with 0.23% fluoridated toothpaste and 0.02% fluoridated gargle with 0.23% toothpaste demonstrated the highest among the other groups. In conclusion. the fluoridated gargle with toothpaste by low concentration showed a significantly greatest synergistic effect on remineralization of the enamel than the other groups.

본 연구는 시판되는 불소양치용액과 불소치약을 4주간 적용한 다음 법랑질 재광화 효과와 화학적 성분에 미치는 영향을 표면미세경도계와 전자현미분석 (EPMA)를 이용하여 비교분석하였다. 경도측정한 결과, 0.23% 불화나트륨이 함유된 불소치약만 적용한 그룹과 0.02% 불소양치용액과 0.23% 불소치약을 병용한 그룹에서는 3주 후부터 그룹 간의 뚜렷하게 유의한 차이를 보였다 (p<0.05). 전자현미분석을 통한 치아의 주요성분인 Ca, P의 정량적인 성분분석을 시행한 결과, 불화나트륨이 함유된 불소치약만 적용한 그룹과 불소양치용액과 불소치약을 병용한 그룹에서는 유의한 차이를 보였다 (p<0.05). P 수치 변화는 모든 그룹에서 통계적으로 유의한 차이를 보이지 않았다 (p>0.05). 그러므로, 본 연구의 결과 저농도의 불소가 함유되어 있는 불소양치용액과 불소치약을 병용 처리한 경우에 칼슘 수치의 증가와 뚜렷한 표면경도의 증가를 보였음을 확인하였으며, 이는 법랑질의 재광화 효과가 있음을 확인하였다.
