[Abstract] Objective This work evaluated the effects of thickness on resin bonding strength. Methods We set the
two bulk-fill composites Filtek Bulk Fill Posterior (FBF) and Tetric N-Ceram Bulk Fill (TBF) as the experimental groups
and the two conventional composites Filtek Z100 (Z100) and Spectrum TPH (ST) as the control groups. The translucen‐
cy parameter (TP), color difference, Vickers hardness (HV), and microtensile bond strength (μTBS) of dentine and the
resin composites were measu
