Abstract
Aim and Objective:To compare and evaluate the micro tensile bond strength of different solvent based one step and two step adhesive systems to dentin.Materials and Methods:Sixty recently extracted human mandibular premolars were subjected for the study and divided into 4 groups of fifteen each. The adhesive materials Single Bond, Prime and Bond XP, Clearfil S3 Bond and G-Bond were applied to flat dentin surfaces according to the manufacturer's instructions. After resin composite build up, teeth were sectioned to obtain beams with an approximate cross sectional area of 2 mm2 and stressed to failure. Data were analysed statistically by ANOVA and student Neuman Keuls multiple comparison tests.Results:The study demonstrated that Single Bond has better bond strength to dentin compared to the other adhesive systems.Conclusion:Ethanol and water based two-step adhesive Single Bond exhibited significantly higher microtensile bond strength values to dentin among all the adhesive systems tested.
