Aim:
This in vitro study aimed to evaluate and compare the effect of a protective coating (G-Coat Plus) on the fluoride release of conventional and resin-modified glass ionomer cements (GIC and RMGIC) in primary molars.
Methods:
A total of 120 extracted primary molars were randomly divided into four subgroups (n = 30) based on the restorative material and application of protective coating: group A-conventional GIC without G-Coat Plus; group B-conventional GIC with G-Coat Plus; group C-RMGIC without G-Coat Plus; and group D-RMGIC with G-Coat Plus. Fluoride release was measured at 1, 2, 3, 4, 5, 6, 7, 14, and 21 days using a fluoride ion-selective electrode and a digital ion analyzer.
Results:
Conventional GIC with G-Coat Plus showed a significant reduction in the initial burst and mean fluoride release up to day 7, comparable release at day 14, and significantly higher release on day 21 compared to conventional GIC without coating. RMGIC with G-Coat Plus demonstrated significantly reduced fluoride release at all time intervals (days 1-7, 14, and 21) compared to RMGIC without coating. Overall, uncoated GIC and RMGIC exhibited significantly higher fluoride release at all measured intervals.
Conclusion:
The study concluded that the application of a protective coating (G-Coat Plus) did not completely inhibit fluoride release from GICs. Instead, it significantly reduced the initial burst and resulted in a gradual decline in fluoride release up to the 21st day.
