Objective: to compare the color stability of three types of resins (Te-econom Plus® - Ivoclar Vivadent, Tetric® N- Ceram Bulk Fill -Ivoclar Vivadent, Filtek ™ Bulk Fill - 3M) immersed in Amazonian substances Myrciaria dubia and Mauritia flexuosa. Materials and methods: 180 resin discs (6mm in diameter and 4mm in height) of each brand were evaluated: Te-econom Plus® - Ivoclar Vivadent, Tetric® N- Ceram Bulk Fill -Ivoclar Vivadent, Filtek ™ Bulk Fill - 3M, divided into 9 groups immersed in Amazonian substances, Myrciaria dubia, Mauritia flexuosa and distilled water (Control group) for 30 days. The specimens were immersed in 20 ml of substances daily at a temperature of 37 ° C ± 5 °. The color evaluation was performed at 7 days, 15 days and 30 days, using a Vita Easyshade® Advance 4.0 spectrophotometer, to find the ΔE values. The results were performed using descriptive and inferential statistics. For univariate analysis, measures of central tendency(mean) and dispersion measures (standard deviation) were used. For the bivariate analysis, the Kruskal Wallis test was used to compare the chromatic stability values of the three composite resins. Results: The Tetric® N-Ceram Bulk Fill resin had lower ΔE values in Mauritia Flexuosa (5.06 ± 2.1) and Filtek ™ Bulk Fill resin had higher ΔE values in Myrciaria dubia (11.42 ± 3.83) at 30 days, unlike Te-econom Plus® resin that did show significant changes in both substances and at all times (6.79 ± 0.67), (16.63 ± 5.29), (11.75 ± 6.57). Conclusions: The Myrciaria dubia (Camu Camu) is the Amazonian substance that presented the highest value of ΔE in the three composite resins and in the three evaluation times. Filtek ™ Bulk Fill resin showed greater color stability. The Te-econom Plus® resin showed lower chromatic stability in the immersion substances in the three established times.
