ABSTRACT
Aim: To evaluate the dislocation resistance of the quartz fiber post/cement/dentin interface afterdifferent adhesion strategies. Methods: Forty bovine lower central incisors were selected andprepared with K-files using the step-back technique, and irrigated with 3 mL of distilled waterpreceding the use of each instrument. Prepared teeth were stored at 37ºC and 100% humidity for 7days. The roots were prepared and randomized into 4 groups. The quartz fiber post was cementedwith an adhesion strategy according to the following groups: GBisCem- BISCEM; GOneStep±C&B- OneStep ± C&B; GAllBond±C&B- AllBond3 ± C&B; GAllBondSE±C&B- AllBondSE ±C&B with a quartz fiberpost. Cross-sectional root slices of 0.7 mm were produced and stored for 24 h at 37° C beforebeing submitted to push-out bond strength. Results: The mean and standard deviation values ofdislocation resistance were GBisCem: 1.12 (± 0.23) MPa, GOneStep±C&B: 0.81 (± 0.31) MPa, GAllBond±C&B:0.98 (± 0.14) MPa, and GAllBondSE±C&B: 1.57 (± 0.04) MPa. GAllBondSE±C&B showed significantly highervalues of dislocation resistance than the other groups. Conclusions: Based on this study design,it may be concluded that adhesion strategies showed different results of quartz post dislocationresistance. Simplified adhesive system with sodium benzene sulphinate incorporation providedsuperior dislocation resistance.
