The aim of this study was to determine the level of fluoride released from four different tooth colored restorative materials; Vitremer, Fuji II LC, Dyract and Tetric ceram in three different storage solutions; artificial saliva, De-ionized water and pH cycling system and also to compare the amount of fluoride released. Fifteen discs of each material were prepared in a Teflon mould, varnish applied, polished, then stored at 37°C and 100% relative humidity for a day. Each storage solution of 2 ml was pipetted into five polypropylene tubes and five samples of each material were suspended individually and the fluoride released was measured using an Orion fluoride Specific Electrode and Digital Ion Analyzer. All the results were statistically analyzed and was concluded that vitremer showed the highest fluoride release followed by Fuji II LC, Dyract and Tetric Ceram in the pH cycling system followed by De-ionized water and least in Artificial saliva.
