Effect of Therapeutic Dose X Rays on Mechanical and Chemical Properties of Esthetic Dental Materials


The aim of this study was to investigate the influence of therapeutic dose X rays on the microhardness (MH) and degree of conversion (DC) of two different esthetic restorative dental materials. The materials were photo-activated with a LED light-curing unit using three cure-times: 5, 20 and 40 seconds. The photo-activation was carried out in two distinct… (More)
