Objective: The purpose of this study was to evaluate the effect of conventional and new generation two flowable composite resins with three different adhesive systems on bond strenght to dentin by using the microtensile bond test.Material and Method: Fourty two non-carious human third molars were sectioned parallel to the occlusal plane to expose occlusal dentin. The dentin surfaces were ground with 600-grid silicon carbide (SIC) paper. Teeth were randomly divided in to six groups (n=7). Group 1-Clearfil S3Bond+ Clearfil Majesty Flow, Group 2-Clearfil SE Bond+Clearfil Majesty Flow, Group 3-Prime&Bond NT +Clearfil Majesty Flow, Group 4-Clearfil S3Bond+ReFil SDR Flow, Gorup 5-Clearfil SE Bond+ReFil SDR Flow, Group 6-Prime&Bond NT+ReFil SDR Flow. The restored teeth were serially sectioned to obtain 1mm2 sticks. Each stick was submitted to the microtensile test performed at a crosshead speed of 1mm/minute. One-way ANOVA, and Tamhane’s tests were used to compare the data.Results:The results indicated that Clearfil SE Bond showed higher microtensile bond strength when compared to the other adhesives in Clearfil Majesty Flow group (p< 0.05). Clearfil SE Bondand Clearfil S3Bond showed similar microtensile bond strength (p>0.05) whereas microtensile bond strength of Prime&Bond NT was significantly decreased (p<0.05). However, in the comparision of the microtensile bond strength values of Clearfil Majesty Flow and ReFil SDR Flow groups adhesive, it was determined a statistically significant difference between two groups for the only Clearfil S3Bond (p<0.05).Conclusion: In the experimental conditions of this study it was seen that adhesive systems may have different effects on the bond strenght to dentine tissue
