Adhesion of Flowable Resin Composites in Simulated Wedge-Shaped Cervical Lesions: An In Vitro Pilot Study

The resin composite restoration of non-carious cervical lesions (NCCLs) still faces some drawbacks mostly related to the quality marginal seal. This study attempts evaluate adhesive capacities two flowable and conventional hybrid restorations NCCLs having types margins. Our null hypothesis assumes same behavior different materials. relative composition dental–restoration structures was also measured. Thus, restored wedge-shaped cavities were realized on both buccal oral surfaces extracted teeth. After immersion in dye solution, sectioning teeth performed. We proposed an optical microscopy method quantify penetration along restoration–tooth interface scanning electron (SEM) energy-dispersive X-ray analysis (EDX) peripheral data obtained revealed amount dentinal microleakage for all tested materials, despite favorable results Therefore, from this failed reject hypothesis. adhesion is not influenced by position SEM occasional disruptions interface. EDX sustains qualitative compositions as provided manufacturers. Conclusions: four experimental composites are recommended restore clinic.
