Abstract :DOI : 10.26650/eor.2018.449 Purpose The aims of this study were; to compare the shear bond strength values of resin-based luting cements using etch-and-rinse, self-etching or self-adhesive techniques and to evaluate the effects of pretreatment with 0.2%, and 2% chlorhexidine insert ignore into journalissuearticles values(CHX); solutions on the bonding stability to dentin. Materials and methods Ninety specimens were divided into 9 groups of equal sample size insert ignore into journalissuearticles values(0.2% CHX, 2% CHX and no CHX application groups);. Variolink N insert ignore into journalissuearticles values(multi-step etch-and-rinse technique);, Panavia F2.0 insert ignore into journalissuearticles values(self-etching technique);, or RelyX U200 insert ignore into journalissuearticles values(self-adhesive technique); resin-based luting cement was applied. All specimens were subjected to shear bond strength test insert ignore into journalissuearticles values(SBS); after bonding procedure. The mode of failure was analyzed by using a stereomicroscope. Results There were no significant differences among study groups for the dentin treatment factor. However, for luting cement factor, significant differences were found and Variolink N showed the highest SBS values. Conclusion CHX application has no immediate effect on the SBS values of any resin cements. Despite the development of simplified cementation techniques, etch-and-rinse technique is still the most reliable technique because of its high bond strength to dentin.
