AIM or PURPOSE: The aim of this in vitro study is to examine the color changes of bioactive materials after the application of different office whitening agents. MATERIALS and METHOD: Atotal of 48 disks (6£2 mm) were prepared using A2 shade of 3 restorative materials; Filtek Z250 (3M ESPE), Equa Forte HT (GC), Activa Bioactive Restor ative (PULPDENT). Samples were divided into 4 subgroups according to the whitening agents used: Group 1: Control, Group 2: Opalescence Boost (ULTRADENT), Group 3: White ness HPMaxx(FGM),Group4:Biowhitten Power HP(BiODENT MEDiCAL) (n=4). The specimen’s upper surface was polished using water-cooled 2000-grit silicon carbide paper and incu bated in an oven in 37°C distilled water for 24 hours. The ini tial and after different bleaching procedures color values of samples were measured with a spectrophotometer. After that, samples were immersed of coffee solution and color measurements were repeated on the 7th day. Color differen ces were calculated by the CIEDE 2000 (DE00) formula. The datas were statistically analyzed. RESULTS: There were statistically significant differences between the color changes of the filling materials initially and after storage in coffee, and Z250 was the least colored (p<0.05). After office bleaching, Activa Bioactive Restorative showed the highest DE00 values (p<0.05). Groups treated with FGM that one of the whitening agents, showed the highest DE00 values in coffee after storage (p<0.05).
CONCLUSION(S): These results show that color stability may be affected depending on the filling material and office whit ening agent used, and therefore this effect should be taken into consideration in clinical applications.
