Abstract

Background:  The effects of fluoride from dental materials in human dentition have proved to be beneficial to prevent secondary caries  The purpose of this study was to evaluate the release of fluoride ions from Glass ionomer cements and Giomer and to compare their fluoride uptake after application of topical fluoride agents: APF gel and NaF gel.  Material & Methods: A total number of 30 specimens of three fluoride releasing dental restorative materials were fabricated of size 5 mm in diameter x 2 mm in height, using a teflon mould and were randomly divided into four groups. These specimens were immersed in 10 ml of artificial saliva and the amount of fluoride released was measured on 1st (24 hrs), 3rd, 7th & 14th day. On 14th day all the specimens of each group were divided into two sub- groups of 5 specimens each and placed in 2ml of APF gel & 2ml of NaF gel for 4 minutes for recharge of these materials and again the release of fluoride from recharged specimens was estimated.  Result: The amount of fluoride released from the various materials was significantly different. The highest release was shown by the Fuji IX followed by Ketac molar and Giomer.
