Abstract
ABSTRACT: Purpose: To evaluate the fluoride release from conventional chemical cure glass ionomer and the resin modified glass ionomer as pits and fissure sealants. Methodology: Thirty extracted human caries-free permanent molars were used in the study and divided into two groups. Group I for resin modified glass ionomer FujiTRIAGE and group II for conventional chemical cure glass ionomer VOCO as 15 teeth in each group, Each tooth was cleaned with water and soft-bristle brush before the fissure sealant was applied according to manufacturer instruction. Then kept in artificial saliva to be examined after 48 hours,7,15,28 days subsequently. Results: This study showed that the resin-modified glass ionomer group FujiTRIAGE exhibit more fluoride release than the conventional glass ionomer VOCO group. Conclusions: Both materials used in this study release fluoride, but there was a difference in each material's fluoride release rate. The initial release of fluoride was higher from resin-modified glass ionomer than from conventional glass ionomer. Both materials exhibited the highest fluoride release in the first 48 hours. Keywords: glass ionomer, pits and fissures, fluoride, sealants, dental sealant
