ABSTRACT


Purpose: The Aim Of This Study Was To Evaluate The Fluoride Release Of New Bioactive Composite Restorative Material (Activa) In Comparison To Two Fluoride Releasing Materials In Vitro At Different Time Intervals.

Materials and Methods: Thirty Specimens Were Prepared 10 Of Each Tested Material (n = 10/group), Activa Bioactive Composite (A1), FUJI II LC Capsules (A2) And Fuji IX Extra Capsules (A3). Specimens Were Prepared According To Manufacturers� Specifications For Each Group Using A Teflon Mold (10mm Diameter By 2mm Depth). Specimens Of Each Material Were Immersed Separately In Deionized Water. Fluoride Release Measurements (?g/cm /day) Were Made1 Day, 1 Week, 1 Month, 2 Months And3 Months. One-way And Repeated Measures Analysis Of Variance Tests Were Used.

Results: The Results Of The Tested Materials Were Collected, Statistically Analyzed Using The ANOVA Test To Determine The Amount Of Fluoride Release Between Different Tested Materials (p<0.001).The Results Indicate That Fuji IX Had The Highest Fluoride Release In Comparison To The Other Activa Bioactive Materials And Fuji II LC Conclusion: All Three Different Restorative Materials Released Fluoride In Deionized Water But Fuji IX Glass-ionomer Showed The Highest Fluoride Release Followed By Fuji II LC And Activa Bioactive Restorative Materials.
