“…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.

Objectives To evaluate and compare the ion-releasing capability of three different restorative systems at the restoration/tooth interface elemental analysis using energy-dispersive X-ray technique. Additionally, micromorphological patterns of the restoration/tooth interfaces was investigated. Materials and methods Eighteen freshly extracted sound human premolars were collected for the study. The premolars were randomly assigned into 3 groups (n = 6) based on the type of restorative materials used: Giomer (Beautifill II), ion-releasing composite (Activa Presto), and RMGI (Riva Light Cure). Half of the specimens in each group were tested after 24 h (the “immediate group”), while the remaining half were tested after 6 months of storage in deionized water (the “delayed group”). Standardized box-shaped cavities along the cervical area of teeth crowns and restored them with the assigned restorative material following manufacturers’ instructions. The specimens were sectioned buccolingually into 2 halves. One half of each specimen was subjected to elemental analysis using energy-dispersive X-ray technique (EDX), while the remaining half was sputter coated and underwent micromorphological analysis of the restoration/tooth interface using a scanning electron microscope (SEM). The collected data from elemental analysis test were tabulated and subjected to statistical analysis. Results The two-way ANOVA test showed significant differences in both phosphorus and calcium levels among the tested restorative systems (p < 0.05). In the immediate subgroup, RMGI recorded the highest phosphorus level (0.1527), followed by the ion-releasing composite (0.1172), while Giomer exhibited the least levels (0.0326) (p < 0.05). The ion-releasing composite group had the highest calcium level (0.2797), followed by RMGI (0.248), and Giomer (0.2385) respectively (p < 0.05). In the delayed subgroups, Giomer recorded the highest phosphorus level (0.1526), followed by the ion-releasing composite (0.1058), and RMGI group (0.0466) respectively (p < 0.05). RMGI had the highest calcium level (0.2801), followed by the ion-releasing composite (0.2659), and Giomer had the lowest level (0.1792) (p < 0.05). The micromorphological analysis of the restoration/tooth interfaces showed good adaptation between the composite and tooth substrate in different restorative groups. Conclusions The ion-releasing capability of the three restorative systems appears to be comparable. The rate of mineral release and diffusion is affected by time and composition.
