Summary

This study checks if a new French questionnaire accurately measures how the look of your smile affects your daily life. Researchers will ask 120 adult dental patients to fill out the survey twice to see if the results are consistent. The goal is to give dentists a reliable way to understand how smile appearance impacts patients' well-being.
