Dual-cured adhesive system improves adhesive properties of dentin cavities restored with a bulk-fill resin composite

Aim: To evaluate the impact of a dual-cured adhesive system on in situ degree conversion (DC), bond strength (BS) and failure mode (FM) interfaces dentin cavities restored with bulk-fill resin composite. Methods: 4-mm-deep 3.1 C-factor were created 68 bovine incisors (n = 17 per group). The lightcured (Scotchbond™ Universal) or (Adper™ Scotchbond™ Multi-purpose Plus) was applied to cavities, which then bulkfill composite (Filtek™ Bulk Fill). In DC analysis performed by means micro Raman spectroscopy at top bottom interfaces. Push-out BS measured universal testing machine after 24-h 6-month water storage. FM determined stereomicroscope. Data analyzed two-way variance (ANOVA) Tukey test (p<0.05), while descriptively. Results: groups that received showed statistically higher than those light-cured system. Cohesive most frequent all conditions. Conclusion: influenced curing strategies systems better performance material.
