Shear Bond Strength of Ormocer-Based Restorative Material Using Specific and Nonspecific Adhesive Systems

الملخص EN

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.
