Purpose: The study has studied the effects of colored nano-hybrid and composite samples of office-type whitening on color change. Tools and Methods: In this study a piece of nanohydrate composite resin Filter Z550, 3M ESPE and a piece of dental color composite Amaris Gingiva, Voco were used. For each resin material, a sample in the form of a disk with a diameter of 20 5 mm and a thickness of 2 mm was prepared and two groups were created by random selection n=10. The samples were kept in containers containing distillated water and coffee solutions for 30 days. At the end of this period the samples are removed from the waiting containers and washed with distillated water after the office type whitening agent containing hydrogen peroxide Opalescence Boost 40% PF, Ultradent Products. He was exposed to the process of whitening. The first color measurement was carried out after the coloring process, and the second was carried out using a spectrophotometer device after the coloring process. The CIE L*a*b* system was used for the resulting color measurements and the color changes on all disks were calculated ΔE*. The color measurement was repeated 5 times for each sample and the average was taken. Independent T-Test used for statistical analysis of the obtained data
