Influence of ultrasound and irrigant solutions on the bond strength of glass fiber posts to root canal dentine

Objective: Assessment of the influence of the ultrasound and irrigant solutions on the bond strength (BS) of glass fiber posts. Material and Methods: Sixty-six roots of bovine teeth standardized at 16 mm were used. The roots were submitted to a biomechanical preparation up to size #80 Kerr file, wi...

description Objective: Assessment of the influence of the ultrasound and irrigant solutions on the bond strength (BS) of glass fiber posts. Material and Methods: Sixty-six roots of bovine teeth standardized at 16 mm were used. The roots were submitted to a biomechanical preparation up to size #80 Kerr file, with irrigation of 5ml of saline solution at every file change and then filled. The canals underwent partial desobturation and were divided into 6 groups according to the irrigant solution and the use of ultrasound prior to the post cementation: S – saline solution; C – 2% chlorhexidine solution; H –2.5% sodium hypochlorite solution; US – saline solution + ultrasound; UC – 2% chlorhexidine solution + ultrasound; UH – 2.5% sodium hypochlorite solution + ultrasound. After the cementation of the posts, the specimens were cut into 3 slices of 2 mm of thickness, perpendicular to its long axis. The samples were submitted to push-out test with crosshead speed of 1 mm/min and load of 50kgf. The data obtained were submitted to ANOVA and Tukey test (level of significance of 5%). Results: Groups C 7.77(±1.8)a, UC 7.82(±1.6)a, S 7.33(±2.2)a, US 6.16(±2.3)a, H 5.43(±1.3)b, UH 5.01(±2.3)b values in Mpa. Only the irrigant solutions showed statistically significant differences (<0.05). Tukey test revealed smaller bond strength for the specimens treated with Sodium Hypochlorite (b). Conclusions: The ultrasound treatment did not show significant difference compared with the other groups; therefore, its use can be indicated prior to the cementation of glass fiber posts without damage to the bond strength. The sodium hypochlorite solution showed the smallest BS values compared with the other groups.
