Abstract

The shear bond strengths between four indirect composite materials and a monomer-preimpregnated glass fiber material were determined in order to evaluate the compatibility of indirect composites with glass fiber material. Four indirect composites (Ceramage, Estenia C&B, New Meta Color Infis, and Pearleste) and a unidirectional long glass fiber material (Estenia C&B EG Fiber) were selected. A250-μm glass fiber plate was light-polymerized and air-abraded. After treatment with a silane primer and a bonding agent, the indirect composite materials were placed on the glass fiber plate and polymerized in accordance with the respective manufacturer's specifications. Shear bond strengths were determined both before and after thermocycling (4 and 60°C, 1min each, 10, 000 cycles) in accordance with ISO 11405. The results were compared using Tukey HSD tests and Mann-Whitney U-tests. The Estenia C&B and Pearleste materials showed significantly greater bond strengths than the other two composites before thermocycling (p<0.05). After thermocycling, there were no significant differences among the Ceramage, Estenia C&B, and Pearleste materials (p>0.05). The New Meta Color Infis material indicated the lowest bond strength among the four composites assessed, both before and after thermocycling (p<0.05). The type of composite material should be considered when selecting the optimal fiber-composite combination.
