불소바니쉬 도포주기에 따른 재광화 평가: QLF-D의 활용 = Remineralization effect according to application cycle of fluoride varnish: QLF-D analysis

다국어 초록 (Multilingual Abstract)

Objectives: The purpose of the study is to investigate remineralization effect according to application cycle of fluoride varnish in preschool children. Methods: The study subjects were fifty six children (92 teeth) having one or more early dental caries lesion. Fluoride varnish was applied to the primary area of maxillary and anterior mandibular teeth with the interval of one month, three months, and six months. Results: Dft index was 3.54 in male and 3.44 in female. The fluorescence loss(△F) value due to early caries lesions showed a significant difference in experiment groups Ⅰ and Ⅱ after the application of fluoride varnish, but there was no significant difference in experiment group Ⅲ. After fluoride varnish application, there was a significant change in experimental group Ⅰ and Ⅲ. The maximum fluorescence loss(△Fmax) from early caries lesions showed a significant difference after application of the fluoride varnish in all three experiment groups of Ⅰ, Ⅱ, and Ⅲ(p<0.001). Conclusions: Fluoride varnish should be recommended and applied to the children of high risk caries group in every three months.
