| dc.description.abstract | Aim: The goal of this study was to evaluate nanoleakage within the hybrid layer yielded by etch-and-rinse and self-etch adhesive systems, with different solvents and compositions. Materials and methods: Four adhesives were applied onto 20 human dentin disks: group A: Adper Scotchbond 1XT™ (3M ESPE), group B: One Coat Bond® (Coltène Whaledent), group C: AdheSE® (Ivoclar Vivadent) and group D: Xeno-V® (Dentsply). The samples were immersed in aqueous ammoniacal silver nitrate for 24 hour, prepared and observed under field-emission scanning electron microscopy with backscattered electrons. Microphotographs were scanned and data were processed. The mean value and standard deviation were calculated. Kruskal- Wallis and Mann-Whitney tests were used (p < 0.05). Results: All the adhesives showed nanoleakage within the hybrid layer: Adper Scotchbond 1XT™ (218.5 μm ± 52.6 μm), One Coat Bond® (139.6 μm ± 79.0 μm), AdheSE® (92.7 μm ± 64.8 μm) and Xeno-V® (251.0 μm ± 85.2 μm). AdheSE® yielded less nanoleakage than Adper Scotchbond-1XT™ (p = 0.003) and than Xeno-V® (p = 0.007). No other statistically significant differences were detected. Conclusion: Two-step self-etch adhesive system (AdheSE®) might contribute for lower nanoleakage deposition and thus better performance in dentin adhesion. Clinical significance: The two-step self-etch adhesive system showed the lowest nanoleakage deposition compared with the other adhesive systems evaluated, which seems to indicate a better behavior when a restoration is performed in dentin and possibly can lead to a durable adhesion along time. | pt_PT |
