Abstract
Aim:The aim of this in vitro study was to assess and compare the effect of the nano-coating on microleakage of different capsulated conventional glass ionomer cement (CGIC), resin-modified glass ionomer cement (RMGIC) and hybrid glass ionomer cement in primary molars. Materials and Methods:A total of 36 primary molars samples were divided into three groups.Group 1 -teeth restored with capsulated RMGIC (Fuji II LC) without nano-coating.Group 2 -teeth restored with capsulated CGIC (Fuji IX) with nano-coating.Group 3 -teeth restored with capsulated hybrid glass ionomer (Equia Forte) with nano-coating.Microleakage was tested using immersed the teeth in 2% methylene blue dye penetration for 24 hours after the thermocycler and measured at x40 magnification under the stereomicroscope. Results:The results of this in vitro study showed that coating with nano-coating showed a reduction in microleakage in hybrid glass ionomer (Equia Forte) and more microleakage in non-coating RMGIC (Fuji II LC) but also more microleakage in coating CGIC (Fuji IX), which was statistically significant.CGIC with nano-coating and RMGIC without coating showed highest microleakage followed by hybrid glass ionomer (Equia Forte) with coating. Conclusion:Significant reduction in microleakage was seen in Equia Forte (hybrid glass ionomer) with nano-coating and the coating should use with all types glass ionomer.
