Each surface of composite resin preparation was photo-ac- tivated for 20 s with a high-power LED (1200 mW/cm2, RadiiCal, SDI, Bayswater, VIC, Australia) and placed into a vacuum-mirrored polymerization chamber (Visio™ Beta Vario Light Unit, 3M ESPE, Seefeld, BY, Germany) using a specific protocol for photo curing materials (1 min of light followed by 1 min of vacuum and light) to increase the conversion degree.	cache/bjos-8658335.pdf	txt/bjos-8658335.txt
