Abstract
This study examined marginal gap formation of composite inlays using a new luting cement (Ionotite F, Tokuyama Dental) and two luting cements (Vitremer Luting Cement Fast Set: 3M ESPE, Fuji Luting S: GC; as controls). This study also examined the shear bond strength to dentin substrate, the flexural properties (strength, modulus of elasticity and fracture of work) and the change of weight of these luting cements in water, which may influence the gap formation.
The sum of marginal gap width and the value of shear bond strength were no significant difference among three luting cements. The flexural strength of Ionotite F was no significant difference compared with for Vitremer Luting Cement Fast Set. The change of weight of Ionotite F was significantly smaller than those of the two luting cements.
