Their anterior teeth in both jaws will be bleached with a photo-activated whitening gel, or will be subjected to a placebo. Lightness, chroma and translucency of teeth will be assessed before (T0), one week (T1) and one year (T2) after the procedure by a spectrophotometer. The subjects in both occasions will administrate the psychometric instrumetns Psychosocial Impact of Dental Aesthetics Questionnaire, Orofacial Esthetic Scale, Oral Health Impact Profile and Smile Esthetics Related Quality of Life. Influence of personality traits on the perception of changes in smile aesthetics and qualiy of life will be also explored (extraversion, conscientiousness, neuroticism, agreeableness, openness to experience, perfectionism, self-esteem, body image).
