Abstract
The goal of the current study was to compare the shear bond values of zirconia-reinforced glass ionomer cement and conventional glass ionomer cement. A collection of 20 extracted premolars with unbroken buccal or lingual surfaces was made. The whole sample was randomly split into two groups: Group A (n=10) which was Conventional Glass Ionomer Cement and Group B (n=10) which was Zirconia Reinforced Glass Ionomer Cement (Zirconomer). The process of thermocycling was used to mimic oral conditions. Using a universal testing machine, the shear bond strength (SBS) was measured after 24 hours at a crosshead speed of 0.5 mm/minute until fracture. After tabulating the results, statistical analysis was done. The findings indicated that Zirconomer exhibited a statistically significant (p ≤ 0.05) higher shear bond strength when compared to traditional glass ionomer cement.
