Aim or Purpose: This study aims to evaluate the remineralization potential of ACTIVA Bioactive restorative material compared to light-cured resin-reinforced glass ionomer restorative. Materials and Methods:A standardized Class V cavity was prepared in forty-two extracted sound human premolars.The mineral content of the teeth was measured before and after demineralization, then the demineralized teeth were left as a negative control (Group I) or restored with either ACTIVA TM Bioactive restorative material (Group II) or light-cured resin-reinforced glass ionomer restorative (Group III).The teeth were stored in artificial saliva for 23h and 1h in lactic acid solution at 37˚C to simulate the oral environment and the acid challenges occurring intraorally.The mineral content was evaluated using energy dispersive x-ray and scanning electron microscope (EDX/SEM) in each group after 24h, 1 month later and after three months.Results: A significant statistical difference in fluoride and calcium release between the two groups was observed.Light-cured resinreinforced glass ionomer restoration showed higher release of fluoride compared to ACTIVA TM Bioactive restorative material while ACTIVA TM Bioactive restorative material showed higher release of calcium compared to the light-cured resin-reinforced glass ionomer.There was no statistical difference in phosphorus release between the two tested materials.Phosphorus content was relatively similar in both groups. Conclusion:Resin-modified glass ionomer materials exhibit greater fluoride release than resin-based materials ACTIVIA Bioactive-Restorative with the highest fluoride release taking place during the first 24 hours.ACTIVA Bioactive-Restorative could be considered a suitable class V restoration in high-caries risk patients.
