Changes in quality of life induced by tooth whitening are not influenced by global self-esteem: a randomized double-blind placebo-controlled trial.

The purpose of this paper is to investigate which elements of tooth colour are most influenced by whitening and to identify the short-term changes in satisfaction with smile aesthetics and quality of life induced by tooth whitening and the role of global self-esteem. Sixty participants were randomly assigned to a treated or a placebo group (each group N = 30). Their anterior teeth were bleached with a photo-activated whitening gel, or subjected to a placebo.

Changes in Quality of Life Induced by Tooth Whitening are Moderated by Perfectionism: A Randomized, Double-Blind, Placebo-Controlled Trial.

Purpose: To explore the influence of perfectionism on the short-term changes in satisfaction with smile esthetics and quality of life (QoL) induced by tooth whitening.

Materials And Methods: A total of 60 subjects were analyzed: 30 in the active group, in which the subject's anterior teeth were whitened with a photoactivated gel, and 30 in the placebo group. The Smile Esthetics-Related Quality of Life and Multidimensional Perfectionism Scale questionnaires were administered to all participants.
