Author(s): Niharika Mishra*, Manish Agarwal, Singh MP, Khushboo Magwa, Sonal Singh Thakur and Sonal Singh Arora
Background: Glass Ionomer Cements (GIC) is not indicated in stress bearing posterior tooth regions due to their low fracture strength, toughness and wear. Resin coatings have been known to reduce such vulnerabilies. G-Coat Plus, a Nano-filled, self-adhesive light cured protective coating that strengthens, protects and enhances glass ionomer restorations. However, there is limited information on their influence on GIC. Hence the study was conducted to compare the effect of resin coating on surface hardness and Shear punch strength of newer modified GIC. Materials and Methods: 120 samples of Fuji IX Extra, Fuji IX Fast, Fuji II LC were prepared using specialized metal moulds. Some were coated with G-Coat plus and some left uncoated. They were then tested for surface hardness and shear punch strength. P < 0.05 was considered as significant. Results: The highest mean value on shear pun.. Read More»
