title: Fluoride release from three different types of glass ionomer cements after exposure to NaF solution and APF gel.
abstract: The objective of this study was to evaluate the fluoride release from three different types of glass ionomer cements and the fluoride release after exposure to NaF solution and APF gel. After determining the fluoride release during 28 days in artificial saliva, specimens were divided into two groups and exposed to NaF solution and APF gel for 2 min during 20 days. For each material, the release was highest during the first day, but Kromoglass released statistically significantly higher amounts of fluoride than the other. Vitrabond and Dyract followed in order. The differences in all groups were not statistically significant after third day. For statistical analysis: Paired- T Test, Variance Analysis and Duncan's Multiple Range Test were used. After exposure to NaF solution and APF gel all glass ionomer cements were recharged but the specimens exposed to APF gel were statistically significantly more recharged than NaF solution. As a result we conclude that glass ionomer cements can act as a rechargeable slow fluoride release systems and especially in caries active children, topical NaF applications with glass ionomer cements could be recommended as a preventive measure. We conclude that these results should be supported with long term and in vivo studies.
