Hybrid Bond (Sun Medical), G-Bond (GC), and iBond (Heraeus) were applied on human ground enamel and dentin either 1) immediately, 2) after 2 min, or 3) after 5 min dark storage under ambient conditions. Venus (Heraeus) composite cylinders were produced in a cylindrical mold clamped on the treated surface. SBSs (n=8) were determined after 24 h storage in 37°C water.
1. The phase-separated stage has no adverse effect on bond strength to enamel or dentin when applied under these conditions.
2. The SBSs of the individual adhesives applied on enamel/dentin are as shown below.
