Abstract
This study aims to evaluate the degree of polymer conversion after photoactivation by transillumination of the interface between resin cements and lithium disilicate glass-ceramic with variations in thickness and photoactivation method. Discs (Ø 7.75 mm) of IPS e.max CAD MT-A2 will be obtained, polished, crystallized, and prepared in three thicknesses: 0.5 mm; 1.0 mm; and 1.5 mm (n=20/thi…
