The aim of this study was to compare the color change Giomer resin composite (Beautifil-Bulk) by using photographs obtained with a smartphone (iPhone 6S) associated Adobe Photoshop software (digital method), spectrophotometric method (Vita Easyshade) after immersion in different pigment solutions.Twenty samples diameter 15.0 mm and thickness 1.0 were confectioned A2 (n = 5). Photographs initial readings performed spectrophotometer, respectively. Then, randomly divided subjected cycles distilled water (control), açai, Coke, tomato sauce, 3 times day, 20 minutes for 7 days. Later, new taken.The analysis (2-way variance, Holm-Sidak, p < 0.05) demonstrated no statistical difference (p 0.005) between methods all groups. Similar changes observed solutions when method. For digital method, clinically unacceptable, sauce similar each other differences Coke açai.Only produced above acceptability threshold both assessment. produce patterns change. According our results, is more recommended
