Abstract

This in vitro study was directed to evaluate the effect of argon laser, visible lights, and light-emitting diode curing devices on fluoride release and fluoride recharge of RMGIC and Giomer. Methodology: This study was categorized into two main groups; the first group; RMGIC restorative material, the second group; Giomer restorative material. Then, each main group was subdivided into three subgroups according to the light-curing unit; argon laser, light-emitting diode, and quartz tungsten halogen. Results: The results of fluoride release and re-release revealed that RMGIC has significantly higher fluoride release when compared to Giomer restorative material at different time intervals and with different light-curing units. Moreover, the results of this study exhibited that the fluoride release and re-release decrease significantly in descending order over the study periods of this study (24 hours, 1 week, 2 weeks, 3 weeks, and at one month) respectively. Also, the results of the present study showed that the fluoride release and re-release decrease significantly in descending order with the use of argon laser, quartz tungsten halogen, and light-emitting diode respectively.
