Abstract

The aim of this study was to evaluate the shear bond strength of ormocer-based restorative material bonded to tooth structure using specific ormocer and nonspecific resin-based adhesives. Human molars were prepared to obtain flat buccal enamel surfaces and flat occlusal dentin surfaces. Admira bond, and Prime & Bond NT, Excite, AdheSE, and Prompt-L-Pop were applied to the prepared enamel and dentin surfaces. Ormocer restorative material was inserted into a mold fixed onto the prepared tooth surfaces. The restorative material was applied and cured. The shear bond strength was measured using a universal testing machine. The highest bond strength was recorded for Admira bond. The non-specific adhesives (AdheSE and Prompt-L-Pop) were recorded the lowest bond strength. Etch & Rinse (Prime & Bond NT and Excite) adhesives were recorded an intermediate values. Admira bond usually showed cohesive failure in the material with enamel and cohesive and mixed failure with the dentin. Etch & Rinse adhesives showed mixed failure with the enamel and, mixed and adhesive failures with the dentin. Self-etching adhesives commonly exhibited adhesive mode of failure. So, Etch & Rinse, non-specific bonding agents can be used with Admira ormocer-based restorative material when the specific adhesive is depleted.
