In vitro influence of amazonian substances on the dental bleaching

Due to the wide scientific divergence of results among in vitro investigations about influence food pigmentation on teeth staining during bleaching, this study aims evaluate laboratory effectiveness at-home bleaching using carbamide peroxide (CP), and in-office hydrogen (HP) applied bovine exposed açaí guarana energy drink dental whitening process. Extracted incisors were randomly separated into six groups as follows: two control (at-home [HB] [OB] immersed artificial saliva), following immersion (HBa OBa), (HBg OBg). The cycle was conducted three times a day for five minutes. After initial reading, color registered subsequently third (and last) week This procedure carried out Easyshade spectrophotometer Vita shade guide. data submitted two-way ANOVA test (p<0.05). showed that after weeks rate OBa group decreased significantly when compared other groups, also those bleaching. process, it observed presented higher rates than ones Therefore, contact with period may reduce efficacy.
