Abstract
Aim: Evaluation of fluoride release from conventional chemical cure glass ionomer and from the
resin modified glass ionomer as pits and fissure sealants
Research question: Which material will show more fluoride release conventional glass ionomer or
resin modified glass ionomer?
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 tooth in each group, each molar tooth was
cleaned by water and soft bristle brush and the fissure sealant was applied on each tooth surface
according to manufacturer instruction then kept in artificial saliva to be examined after 48
hours,7,15,28 days subsequently .
Results: The result of this study showed that the resin modified glass ionomer group FujiTRIAGE
exhibit more fluoride release than conventional glass ionomer VOCO group.
Conclusions: Both materials used in this study release fluoride, but there is a different in fluoride
release rate for each material.
The initial Fluoride release was highest from Resin modified glass ionomer followed by
conventional glass ionomer.
Both materials exhibited the highest fluoride release in the first 48 hours.
