Sažetak
Light source for photopolymerization is of great importance to ensure an adequate clinical composite filling. Halogen lamp is the comonly used unit for polymerization of composite materials in everyday clinical conditions. The development of new blue superbright light emitting diodes of 450 and 470 nm wavelengths represents an alternative to the halogen lamp. The purpose of this study was to compare the degree of conversion of three hybrid composite materials Tetric Ceram (Vivadent, Schaan, Liechtenstein), Pertac II (ESPE, Seefeld, Germany) and Valux Plus (3M Dental Products, St. Paul, MN) after illumination with the standard halogen lamp. Heliolux GTE (Vivadent, Liechtenstein) of 600 mW/cm2 intensity and blue superbright light emitting diodes (Nichia, Japan) of minimal intensity of 9 mW/cm2. The results revealed only a slightly higher degree of conversion values in the case of polymerization, with even 66 tiems stronger halogen lamp.
