About this trial

This cross-sectional study aims to evaluate how interdental spacing and crown width discrepancies in primary dentition influence the perception of smile esthetics. Standardized smile photographs obtained from children with physiologic spacing patterns will be digitally modified to create different dental scenarios, including variations in interdental spacing, midline deviation, and crown width discrepancies. The images will be presented to adult participants, including dental students and parents, who will evaluate the esthetic appearance of each smile using a visual analog scale (VAS). The study seeks to determine how different spacing patterns and tooth size discrepancies affect the perception of smile esthetics in primary dentition.
