Abstract
Purpose:
To evaluate the shear bond strength over a variety of conditions of a new dental adhesive having the primer and bonding resin in a single bottle.
Materials And Methods:
Facial surfaces of extracted human molars for the dentin study and labial surfaces of incisors were treated with the One-Step adhesive after both etching and nonetching, variable etching times and variable rinsing times. Composite cylinders were attached and shear bond strengths were obtained.
Results:
The bond strength data was quite consistent over a wide variety of conditions. The bond strengths were in the range of 23-29 MPa to dentin, and compared favorably with the performance of the adhesive to etched enamel surfaces.
