Abstract: Background-Bond strength of Glass Ionomer cements with tooth structure directly influence the clinical performance of the glass ionomer cement. In this in vitro study, aims to measure and compare micro-tensile bond strength (tbs) of Zirconomer- a newly introduced Glass Ionomer Cement with Conventional Glass Ionomer Cement and Resin- modified Glass Ionomer cement (RMGIC). Materials and methods- The specimens were divided into 3 groups: 1) Group I: Comprises of 4 teeth in which dentin was bonded to conventional GIC, 2) Group II: Comprises of 4 teeth in which dentin was bonded to RMGIC, 3) Group III: Comprises of 4 teeth in which dentin was bonded to zirconomer. After GIC build-ups, specimens were sectioned vertically into 2 x 2 x 6-mm3 beams and each specimen was subjected to tbs test. Results- Intergroup comparison using One-way ANOVA followed by pairwise comparison using post hoc test showed that tbs of RMGIC was significantly higher than both Conventional GIC and Zirconomer (p< 0.05. ) tbs values for zirconomer were higher than those for Conventional GIC however the difference was not statistically significant.
