Abstract: Objective. Evaluate the bond strength of a resin cement used to lute carbon fiber posts, when drills and 4 different substances were used for the post-space preparation. Study design. Forty human canines were treated endodontically, and had a 10-mm length post space preparation. Four different substances were used with the drills: G1 - saline, G2 - 2% chlorhexidine gel, G3 - EDTA/NaOCl, and G4 - xylene. Carbon fiber posts (C-Post) were cemented with Allbond2 and Hi-X. Then, the posts were dislodged by tensional forces. Results. The groups of chlrohexidine (G2) and xylene (G4) obtained superior average values of bond strength at the 5% significance level (Parametric analyzes ANOVA/Tukey/Scheffe) differing statistically from the other groups. There was no statistical significant difference between groups 2 and 4. Conclusion. Xylene and chlorhexidine gel are good substances for the post-space preparation but the second has the advantage of antimicrobial activity and low toxicity.
