Abstract: The aim of the study was to evaluate the bond strength of fibre glass and carbon fibre posts in the root canal walls cemented with self‐adhesive (RelyX‐Unicem) and chemical (Cement‐Post) resin cements. Forty maxillary canines were divided into four groups according to the cement and post used and submitted to the push‐out test (0.5 mm min−1). The data were submitted to statistical analysis (2‐way anova, Bonferroni –P < 0.05) and fracture analysis by Scanning Electronic Microscopy. Fibre glass presented the best results when cemented with RelyX‐Unicem and Cement‐Post (P < 0.05). RelyX‐Unicem presented the highest bond strength values for both posts (P < 0.05). Fracture analysis showed predominance of cohesive fracture of post for RelyX‐Unicem and adhesive fracture between dentin/cement and mixed for Cement‐Post. The bond strength values were significantly affected by the type of post and cement used and the highest values were found for fibre glass posts and RelyX‐Unicem.
