摘要: Abstract Objectives The purpose of this study was to evaluate how curing protocol affects the extent polymerization dual-cured resin cements. Methods Four commercial cements were used (DuoLink, Panavia F 2.0, Variolink II and Enforce). cured under different conditions measured using a 1H Stray-Field MRI method, which also enabled probe molecular mobility in kHz frequency range. Results Resin show well distinct behaviours concerning chemical cure. Immediate photo-activation appears be best choice for higher filler loaded (Panavia 2.0 Variolink). A delay (5 min) did not induce any significant difference all Significance considerably changed among products various protocols. Clinicians should optimize materials taking into account characteristics
