Methods: 80 flat enamel disks (3 mm diameter and 1 mm thick) were obtained from bovine incisors. The initial fluorescence (fluorescent emission or Delta E*ab- FL units) of the specimens was measured using a spectrophotometer. Artificial caries was created in all specimens, and the measurements were repeated. The specimens were divided into four groups according to the treatment applied (n = 20): CON (control) - immersion in ultrapure water for 8 weeks; SAL - immersion in artificial saliva for 8 weeks; FL - daily application of 0.05% sodium fluoride for 1 minute/artificial saliva for 8 weeks; and ICON - resin infiltration (Icon). After the treatments, the assessments were repeated. Dental bleaching using 35% hydrogen peroxide gel was performed on all specimens for 30 minutes, and the measurements were made again after 7 days. Data were submitted to ANOVA and Tukey tests across the treatments for each moment of evaluation. Results: Fluoride and saliva remineralization were not able to change enamel fluorescence, even after bleaching. Only resin infiltration increased the enamel fluorescence; however, after bleaching, all groups presented similar values. Icon increased translucency immediately after application, but bleaching reduced it to its initial values.43-46engArtigoWOS:000460844300008Acesso restrito
