| Summary: | Objective: To measure fluoride release and recharge ability of
restorative materials in deionised water, artificial saliva and lactic
acid.
Materials and Methods: Pellets were prepared from GC2, Ketac
N100 and Beautifil II. Each pellets were individually immersed
in 10 ml deionised water, artificial saliva or lactic acid as per
respective subgroup for 24 h and then elutes were collected.
Specimens were reimmersed in respective container. Fluoride
released was analysed after 24 h, 7th and 15th day. On 15th day all
specimens were exposed to 1.23% APF gel and fluoride release
in respective solution was measured on 16th, 22nd, 30th day.
Result: Fluoride release was more after 24 h for all materials in all
media then decrease gradually. GC2 shows more fluoride release
than Ketac N100 at 24 hours and on 7th day but onwards Ketac
N100 released significantly more fluoride. Beautifil II showed
least fluoride release at all measured intervals in all media. Order
of fluoride release in media was lactic acid > deionised water >
artificial saliva for all materials.
Conclusion: GICs are smart material which release more fluoride
when environment become more acidic and also show tendency
to recharge which helps clinically in caries risk children. |
