摘要: The aim of this in vitro study was to explore light transmission through an individually formed fiber-reinforced composite (FRC) post compared with two prefabricated FRC posts. Three different glass posts from manufacturers were used: groups included (RelyX and GC Fiber Posts) one group consisted E-glass semi-interpenetrating polymer network (semi-IPN) matrix (everStick Post). Various lengths lightprotected cylinders made. specimens light-polymerized on the test tray a radiance testing device (MARC Resin Calibrator). Light direction fibers registered. decreased increasing length (p≤0.001; ANOVA) up 12 mm all groups. showed highest cylinder (p<0.001) posts, which could benefit polymerization material luting cement.
