In the present study, we investigated the chemical interaction between 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) and methacryloxypropyltrimethoxysilane (gamma-MPS) in one-bottle primer solutions and its effect on dentine bonding performance. Solutions containing 10 wt% 10-MDP and/or gamma-MPS at 0, 1, 5, 10, or 15 wt% were prepared, providing 10 experimental groups (labeled MDP/MPSxx or MPSxx, where MDP indicates the presence of 10 wt% MDP and xx is the wt% of gamma-MPS in the solution). Phosphoric-acid-etched dentine blocks were prepared from human molars and conditioned in the solutions before being used to build resin-dentine-bonded specimens, which were subsequently subjected to microtensile bond strength (μTBS) testing after 24-h or six-months water storage.
