Abstract:
The purpose of this study was to determine the ion release from four commercially available pit-and-fissure sealants [3M Clinpro,3M ConciseTM,BeautiSealant (BS),and GI FX-Ⅱ)].With each brand,18 specimens were prepared.Their fluoride release in de-ionized water was measured by fluoride electrode,while the release of silicate (Si),aluminum (A1),sodium (Na),calcium (Ca),strontium (Sr),and phosphorus (P) was measured by inductively coupled plasma atomic emission spectroscopy (ICP-AES) on days 1,3,7,14,21,and 28.The result showed that fluoride was not released from 3M ConciseTM.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 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 GI FX-Ⅱ,but not from the 3M Clinpro and 3M ConciseTM.Additionally GI FX-Ⅱ had the largest Si release among the four brands at any time during the experimental period (P＜0.001).Ca ions were detected from 3M 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 the amount of ion release,BS is the best pit-and-fissure sealant among the four brands.
