Summary

This completed study with 210 adults looked at whether the sequence in which a dentist shows tooth color options influences a patient's final shade selection. Participants were randomly assigned to see natural shades first, bleached shades first, or all shades at once. The goal was to measure how often and how much patients changed their choice based on presentation order, and whether self-consciousness about their smile played a role.
