摘要: This study determined the effect of different light exposure times on polymerization three composite resins used as cements (Heliosit, Visio-Fil, and Dual) through various thicknesses shades two preprocessed (Isosit Visio-Gem). The Knoop hardness surface luting resin was measured after selected samples were remeasured at 24 hours to evaluate continued cure. Results indicated that light-activated agents cannot predictably be accomplished a restoration exceeding 2 mm in thickness using 90 seconds or less. combined chemical cure Dual cement recorded highest percentage acceptable values.
