The Impact of Dietary Counseling on the Efficacy of Tooth Bleaching: a Randomized Controlled Trial

Forty patients will be divided into two groups and randomly allocated to each group: usual diet (control) or white diet, avoiding dye-containing food and beverages. patients will be assessed through a food frequency questionnaire and color measurement using a spectrophotometer at baseline and six months after bleaching.
