Abstract
Introduction The potential of remineralization of carious lesions in dentin in vitro by glass-ionomer cements (GIC) has been long established [1], and related to the release of fluoride ions from the restorative material. Diffusion of additional ions from GIC, like calcium, strontium, and magnesium have an important effect on demineralized dentin

The potential of remineralization of carious lesions in dentin in vitro by glass-ionomer cements (GIC) has been long established [1], and related to the release of fluoride ions from the restorative material
Clinical significance: The results showed that a continuous exchange of ions between enamel and dentin and glass-ionomer material occurs in vivo and the concentration of the ions is time related
Alumina and fluorine in enamel and dentin may cause a continuous anti bacterial and anti cariogenic effect, while calcium enhance mineralization of glass-ionomer in vivo, a factor that may increase the longevity of the restoration
Summary
The potential of remineralization of carious lesions in dentin in vitro by glass-ionomer cements (GIC) has been long established [1], and related to the release of fluoride ions from the restorative material. The levels of calcium, phosphate and fluoride in primary molars restored with GIC were higher than in intact teeth after one month in vivo [3]. In carious teeth the concentration of strontium was significantly lower when compared to intact teeth [10-11]. Phosphate and fluorine was significantly lower in patients with high carious activity in comparison with patients with low carious activity [12]. Strontium and fluorine can be found in glass-ionomer cements used for bases or restorations of primary and permanent teeth. In vitro analyses showed that there is a chemical exchange of fluorine and strontium ions between glass-ionomers restorations and
