ASSESSMENT OF THE INFLUENCE OF APPLICATION TIME OF DIFFERENT APF AGENTS ON THE ENAMEL FLUORIDE UPTAKE AND ANTICARIOGENICITY

서로다른 APF 제재의 적용시간에 따른 법랑질내 불소 흡수량 및 우식 억제효과에 관한 비교 연구

The purpose of this study was to compare the enamel fluoride uptake and anticariogenic effect following topical application with different physical form of fluoride and application time. The results can be summarized as follows: 1. While the 4-minute applicaton increased the enamel fluoride uptake significantly than 1-minute application regardless of physical form of applied topical fluoride agents, no siginificant difference could be found between foam and gel type when applied for the identical period of time. 2. The application time or the physical form of topical agents had no singificant influence on the reduction of caries lesion. 3. Based upon the above-mentioned results of this study, it cannot be concluded that the amount of enamel fluoride uptake has an absolute impact on the change of lesion depth. Therefore, the clinical application of 1-minute topical fluoride application which appears to have a similar anticariogenic efficacy to 4-minute fluoride application may be encouraged.
