Abstract
The aim of this study is to evaluate the influence of thermomechanical fatigue in the bond strength (BS) of repaired composite using two different adhesive systems. sixty samples will be made with Filtek Z350 which will be separated into four groups: 01 - without repair (control), group 02 - without repair and with thermomechanical fatigue, group 03A - with repair with 3 steps adhesive wi…
