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.",[41,42,43],"Smile Esthetics","Interdental Spacing","Esthetic Perception",[45,46,42],"aesthetics","primary dentition","NOT_YET_RECRUITING","2026-04-01",{"date":50,"type":51},"2026-04-07","ACTUAL",{"date":53,"type":37},"2026-04",{"date":55,"type":37},"2026-06",{"name":5,"class":6}]
