Evaluation Of Ion Release From Four Dental Sealants

The purpose of this study was to evaluate ion release from pit-and-fissure sealatns-3M Clinpro,3M Concise?,BeautiSealant,GI FX-II.72 samples were prepared and put in de-ionized water.The release of fluoride was measured by fluoride electrode,while the release of silicate,aluminum,sodium,calcium,strontium,and phosphorus was measured by inductively coupled plasma atomic emission spectroscopy(ICP-AES).Ions release was measured in the 1st day,3rd day,7th day,14 th day,21 st day,28 th day.The result showed that GI FX-II displayed the largest fluoride release,which,however,dropped rapidly on day 3.3M Clinpro exhibited less fluoride release than GI FX-II and BS did.At any time during the 28-day experimental period,GI FX-II released more Na and Si than the other sealants(P<0.001).BS ranked the second in Na release,and a small amount of Na ions was released from the 3M Clinpro and 3M ConciseTM samples.A1 ions were only detected from BS and GIFX-II,but not from the 3M Clinpro and 3M ConciseTM.Ca ions were detected from3 M Clinpro and 3M ConciseTM,but not from GI FX-II.BS released more Sr than the other sealants at any time during the experimental period(P<0.001).All the samples released similar amounts of P continuously during these 28 days.In conclusion,based on the type and amount of ion release.BeautiSealant is the best pit and fissure sealant among the four brands.
