AIM: The aim of this study was to assess the influence of resin cement insertion methods on the bond strength of a fiber post to root dentin and quality of the cement layer.
METHODS: Forty bovine single-roots (length =16 mm) were randomly allocated into four groups, according to the cement insertion methods (N.=10): Gr1- Lentulo drill #40, Gr2- Centrix syringe, Gr3- Explorer #5, Gr4- fiber post. The root canals were prepared at 12mm, using preparation bur # 3 of a cylinder quartz-FRC post (Aesthet post-plus, Bisco). The fiber posts were cemented using a multi-step etch-and-rinse adhesive system (All Bond 2®, Bisco) and a dual-cured resin cement (Duolink, Bisco). Each root was cut into seven samples: four samples of 1.8 mm thickness for push-out testing, and three with 0.5 mm for cement layer quality analyzing. One-way ANOVA was used for the push-out test values and the One-Way Kruskal-Wallis (P<0.05) and Dunn (10%) tests for the cement layer analyzes.
RESULTS: ANOVA showed that the cement layer quality was affected by the cement insertion methods (P=0.0044): Gr1 (3.8±1.3a), Gr2 (3.2±1.3a), Gr3 (5.2±1.5a,b) and Gr4 (5.2±1.5b) (Dunn test), whereas the bond strength (MPa) was not affected by cement insertion methods: G1 (4.2±1.3), G2 (3.2±1.8), G3 (4.5±0.9), G4 (3.1±1.3).
CONCLUSION: The fiber posts should be cemented with the assistance of the lentulo drill or centrix syringe to promote the best cement layer results.
