Microtensile bond strength of universal adhesives to flat versus Class I cavity dentin with pulpal pressure simulation

ConclusionsµTBS to dentin of universal adhesives is more stable in the long term following the SE than TE protocol. Simulated pulpal pressure and cavity‐type sample preparation may be recommended for µTBS testing as a more clinically relevant strategy.
Clinical SignificanceMicrotensile bond strength to dentin of universal adhesives appears more stable following the “self‐etch” than “total‐etch” protocol after long‐term degradation. More clinically relevant data may be obtained using simulated pulpal pressure and cavity‐type sample preparation in the study design.
