    Objective: The aim of this in vitro study was to investigate the fluoride-releasing/recharging and antimicrobial effects of restorative materialsused in pediatric dentistry.Material and Method: High-viscosity and resin-modified glass-ionomercement, glass carbomer, compomer, giomer and composite weretested. Dental materials’ fluoride-release was measured in distilled water(DW) and artificial saliva (AS) for eight weeks using a fluoride-specificelectrode. At the end of eight weeks, specimens were divided intothree groups for recharging with acidulated phosphate fluoride gel andfluoride varnish. After recharge, fluoride release was measured again.Agar diffusion test was used to assess antimicrobial effects againstS. mutans and L. acidophilus. The statistical analysis was done withMann-Whitney U and Friedman tests using SPSS-22 software.Results: High-viscosity glass-ionomer cement showed the highestfluoride-release in both storage media, followed by glass carbomer,while giomer demonstrated the lowest. After recharge, the increasein the varnish group was significantly higher than others (p<0.05).Fluoride-release in DW groups was significantly higher than in the ASgroups for all materials during the test period (p<0.05). None of thematerials showed antimicrobial effects.Conclusion: It was concluded that fluoride-release from glass ionomer-based materials is higher than that from resin-based materials.Fluoride-release from materials decreases in AS. Glass carbomer can beused as an alternative to glass ionomers.
