Abstract
AIM: To evaluate the dentin adhesive bond strength of 3 bonding systems. METHODS: Dentin of 30 extracted human molars was exposed by removal of the occlusal enamel. The teeth were then randomly divided into 3 groups( n = 10). A block of composite resin was bonded to dentin of th teeth respectively with Single Bond 2, Easy One and SE Bond according to manufactures' instructions. The teeth were cut vertically to their bonded surfaces and sectioned to obtain slice- shaped specimens with a slow-speed saw. Then the specimens were trimmed into columns with the bonded surface area of 1. 0 mm2. The bonding strength of the specimens was measured by a Microtensile Tester. A microscope was used to observe the fracture modes. Data were statistically analyzed. RESULTS: The mean bond strength( MPa) of Single Bond 2,Easy One and SE Bond was 23. 40 ± 6. 20,16. 25 ± 4. 42; and 16. 17 ± 4. 78 respectively. Single Bond 2 vs Easy One or SE Bond,P 0. 05; Easy One vs SE Bond,P 0. 05. CONCLUSION: Single Bond 2 can prodce stronger bonding strength to dentin than SE Bond and EASY OEN.
