The optimal bonding of adhesives to dentin requires the sealer to be completely removed from dentinal walls. The aim of this study was to investigate the effect of different cleaning procedures using gutta-percha solvents on bond strength of adhesive resins to AH Plus contaminated dentin (APCD). The pulp chamber dentin surfaces were contaminated with AH Plus and cleaned with five different techniques (dry cotton, chloroform, orange oil, eucalyptol, and ethanol). Then, Clearfil SE Bond (CSE) (Kuraray), and Tetric N Bond (TNB) (Ivoclar Vivadent) were applied and filled with a composite resin. The serial sticks (1x1mm) were obtained and tested for microtensile bond strength. Scanning electron microscopy (SEM) was used for analysis of debonded surfaces. Ethanol exhibited the highest bond strength to APCD followed by dry cotton. There was no statistically significant difference between ethanol and dry cotton (p>0.05). Eucalyptol showed the lowest bond strength to APCD and statistically significant differences (p<0.05) in comparison with other groups. APCD reduced the bond strength of all adhesive resins. Dry cotton, ethanol, and chloroform were the most suitable techniques when used with CSE together, whereas ethanol was best with TNB. SCANNING 37:138-144, 2015. (c) 2015 Wiley Periodicals, Inc.
