A comparative evaluation of microleakage and dentin shear bond strength of three restorative materials

Abstract

AIM: To evaluate the microleakage and dentin shear bond strength of two glass containing restorative materials, Zirconomer and Cention N, and to compare them with a conventional glass ionomer cement (GIC) (GC Fuji II). MATERIALS AND METHODS: = .05). RESULTS: Cention N displayed significantly less microleakage than did Zirconomer and GC Fuji II at occlusal as well as the gingival margins. Dentin shear bond strength varied significantly between 5.15 and 9.89 MPa with Cention N showing the highest bond strength and GC Fuji II the lowest. CONCLUSION: evaluation, Cention N consistently performed better than the conventional GIC (GC Fuji II) as well as Zirconomer.
