Composite bond strength to intact enamel with current simplified adhesives.

Purpose: This study compared microtensile bond strength (μTBS) of six simplified adhesive systems and an etch-andrinse, one-bottle adhesive system to intact enamel.

Materials And Methods: Twenty-eight sound incisor teeth were cut at the cementoenamel junction (CEJ) under water cooling. The enamel surfaces were cleaned with pumice, randomly assigned to seven groups and treated with one of the following adhesives: Hybrid Bond (Sun Medical); AdheSE One (Ivoclar/Vivadent); One Coat 7.
