Background:The antibacterial effect and cariostatic properties of glass -ionomer cement are associated with the amount of fluoride released ,therefore the aim of the study was to evaluate fluoride release from three different glass ionomer cement (GIC)-based restorative materials .Materials and methods :a total of 42 samples of extracted caries free permanent molars were obtained as 14 samples in each group .group A(FujiIX:resin modified glass ionomer cement),group B (Voco:TGIC) and group C (Ketac Molar) each tooth was prepared for conventional class I cavity preparation , followed by application of the restorative material then kept in artificial saliva to be examined for fluoride release after 48hours,7,15,28 days using Orion fluoride electrode.Results: according to this study ,there is different in fluoride release between the study groups according to the time interval ,where group A showed the statistically significant value in relation to group B&C(P<0.005).Conclusions :this study showed that FujiIX was the material of the highest fluoride release value.KEY WORD : fluoride release, glass ionomer cement, fujiix, vovo, ketac molar .

“…The amount and the pattern of fluoride release from ACTIVA BioACTIVE in present study are comparable to that result of other studies [10,18,19,23] ; in fact, most of the polymer resins have developed very low fluoride ions (within 30-60 days, less than 0.02-2 ppm ) [23] , which has been supported by our result.…”

“…Consequently, A substrate that may produce both fl uoride and calcium ions will be required to improve the production of fl uorapatite on the surface of the tooth [9,18] . Specimens were soaked in distilled water to act as a baseline for fl uoride release in an unstimulated environment, no organic molecules or minerals that might affect the results, and more fl uoride is released in water than in synthetic saliva [10,18,19] . Ion chromatography was used to evaluate the fl uoride release owing to its sensitivity to measure accurately even the low concentration of fl uoride [19,20] .…”

Objectives: This study was designed to develop and assess the ions release property of an innovative experimental bioactive fiber-reinforce composite as a new material for an intra-canal post. Study Design: An in vitro studyMaterials and Methods: Surface treated unidirectional E-glass fiber were impregnated and implanted with a triple cure, self-adhesive ACTIVA BioACTIVE resin cement to fabricate an experimental bioactive glass fiber post using hand lay-up moulding technique and polytetrafluoroethylene (PTFE) moulds, The cylindrical and rectangular form specimens were prepared, for each specimen, ensure 3min for self-cure setting, then light-cured for the 40s. The specimens were individually immersed in a deionized (DI) water, and sodium chloride solution to assess the fluoride ion release, and calcium-phosphate ions release sequentially. Virgin ACTIVA BioACTIVE cement was used as a reference group for all investigations.Statistical analysis used: Statistical analysis was achieved by means of independent variable t-test, oneway ANOVA, and Bonferroni Pairwise comparisons utilizing IBM-SPSS software.Results: Experimental material recognized a significant reduction in F -, Ca +2, and PO 4 3release after reinforcement compared to virgin ACTIVA BioACTIVE. Conclusions:The ACTIVA BioACTIVE cement's reinforcement process reduced the ion release intensity of the material but not affected the releasing pattern.

“…8,10 Fluoride has remineralization activity that helps strengthen tooth tissue structure and inhibits demineralization by combining fluoride with calcium to form fluoroapatite. 8,12,13 This bond is more stable and more resistant to acids due to the bond structure formed is more complex. 13 The ability of bioactive resin to take and release fluoride is dependent on factors such as fluoride content and also changes of oral pH.…”

Background: Bioactive resin can release fluoride ions when contact with oral environment. In the oral cavity, saliva and metabolic results of Streptococcus mutans namely lactic acid may affect the release of ions due to pH changes. Purpose: to analyse the release of fluoride ions of bioactive resin in the solution of lactic acid and artificial saliva. Methods: Forty-two specimens (diameter 15 mm x thickness 1 mm; n= 7/group fabricated with Activa™ Bioactive Restorative (Pulpdent). The specimen swere randomized into six 6 groups which immersed in lactic acid, artifial saliva and distilled water for 1 and 7 days in the incubator at 37oC. The number of fluoride ion release was measured using pH Meter (Lutron-208). Results: Two Way Anova test and Post Hoc Bonferonni test show there are significant differences among all group for lactic acid 1 day (6.37 ± 0.74), artificial saliva 1 day (1.30 ± 0.48), distilled water 1 day (3.78 ± 0.97), lactic acid 7 days (22.9 ± 0.81), artificial saliva 7 days (19.00 ± 0.81), distilled water 7 days (21.60± 1.01) ppm. Conclusion: The fluoride ion release of bioactive resin which immersed in lactic acid solution was higher than in artificial saliva immersion. Keywords: Artificial saliva, Bioactive resin, Fluoride ion release, Lactic acid
