Effect of Different Fiber-Reinforced Composites on the Microtensile Bond Strength to Dentin: An In-Vitro Study

Description :

This study aims to investigate the impact of fiber reinforcement on the bond strength of composites to dentin. The preparations will be Class I cavities on human-extracted molars. The control group will involve the teeth restored with the conventional composite (G-ænial A’CHORD, GC, Tokyo, Japan). In the first experimental group, the Ribbon Fibers (Ribbond, Seattle, WA, USA) will be applied to the cavity floor and covered with the conventional composite. In the second experimental group, a short fiber-reinforced composite (SFRC) (EverX Posterior, GC, Tokyo, Japan) will serve as the initial layer followed by coverage with the conventional composite. In the third experimental group, a flowable short fiber-reinforced composite (EverX Flow, GC, Tokyo, Japan) will serve as the initial layer followed by coverage with the conventional composite. The micro-tensile bond strength to dentin will be compared among the 4 groups and measured with the universal testing machine (YLE GmbH, Waldstraße Bad König, Germany).
