Fluoride release from Iraqi made glass ionomer cement. A comparative study

This study was carried out to determine the fluoride release from Iraqi and two imported glass ionomer cements by placing(15) specimens(five for each type of glass ionomer cement) in a polyethylene container filled with deionized water and TISAB. Measurements of fluoride release were taken daily for(8) days following specimen preparation followed by onceweekly for a month Mean daily fluoride release was plotted against time. The results showed that there was a significant difference between Iraqi and Hibond materials within the same period of fluoride release and no significant difference between Iraqi and Degussa cements
