Materials and Methods: Forty samples of glass ionomer restorative material in acrylic mold were distributed in four groups: G1: control-uncoated Fuji IX, G2: coated with ScotchBond Multipurpose, G3: coated with Excite F, and G4: coated with L-pop adhesive system. Each specimen was stored in a centrifuge tube containing 4ml of artificial saliva in 37oC. Fluoride release of each sample was measured daily from day 1 through day 10, and on day 14 and 15, by using fluoride ion specific electrode probe. Data were analyzed with one-way ANOVA for the cumulative fluoride release over the span of 15 days, as well as day 1 values. Kruskal-Wallis and Mann-Whitney U tests were used for the fluoride release at other time points, day 2 and day 3. Results: The Fuji IX coated with L-pop adhesive showed significantly higher amount of fluoride release, followed by the control group, the uncoated Fuji IX. (p<0.05). There was no significant difference between the groups coated with ScotchBond Multipurpose and Excite F. The highest amount of fluoride release was shown within the first 24 hours immediately after restoration placement among all four groups. Conclusion: With consideration to the limitations of an in-vitro study, we conclude that L-pop bonding agent (6th generation adhesive system), increased the amount of fluoride released from the glass ionomer. We also concluded that ScotchBond Multi-purpose (4th generation bonding system) and Excite F (5th generation bonding system) acted as a barrier and reduced the release of fluoride from the glass ionomer.; Thesis (M.S.)--Tufts University, 2014.; Submitted to the Dept. of Pediatric Dentistry.; Advisor: Masly Harsono.; Committee: Cheen Loo, Matthew Finkelman, and Gerald Swee.; Keyword: Dentistry. %[ 2022-10-12 %~ Tufts Digital Library %W Institution
