Sažetak
One of the most important side effects of composite material setting using halogen devices besides polymerization shrinkage is temperature rise. The temperature rise is in direct relation with the strength of polymerization light intensity and as intensity grows so does the temperature. Since many polymerization devices exist on the market today capable of producing several different polymerization modes with different distribution of light intensity within the polymerization interval as well as different strength, the purpose of this study was to examine the influence of different polymerization programs (modes) on temperature rise in a sample of composite material. In the experiment Tetric Ceram (Vivadent, Schaan, Liechtenstein) and Filtek Z 250 (3M/ESPE Dental Products, St. Paul, MN) composite materials were used. Composite material samples were polymerized by Elipar Trilight halogen device (3M/ESPE, Seefeld, Germany) with three polymerization modes of various intensities (middle (ET ), exponential (ETE) and standard (ETS)). Highest temperature rise was noted after 40 seconds at highest intensity mode (standard mode), while lowest temperature rise was noted at exponential mode after 10 seconds and at medium intensity mode after 40 seconds.
