Abstract

Aim of this study was to compare the shear bond strength between Zirconomer and bonded amalgam using various bonding agents and compressive strength of Zirconomer and silver amalgam. In shear bond strength analysis, 1 mm of the crown surface of forty maxillary premolars was cut to expose the crown dentin. Smear layer was created on the exposed dentin surface and specimens of Zirconomer, Amalgam bonded with Fuji 1 GIC, Amalgam bonded with Resin Modified GIC, Amalgam bonded with RelyX ARC resin cement were formed using a silicon mold with 5mm height and 4mm diameter. Specimens were then bonded to dentinal surface. For compressive strength analysis, ten samples each of Zirconomer and Silver Amalgam with the dimensions of 4.0 mm diameter × 6.0 mm height were evaluated. Both the analysis was carried out using universal testing machine. The highest shear bond strength was seen with the bonded amalgam with RelyX ARC adhesive resin cement group. Shear bond strength of Zirconomer was similar to that of bonded amalgam with Fuji I GIC and bonded amalgam with RMGIC. Silver amalgam showed a higher compressive strength than Zirconomer.
