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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Children without any systemic disease
Children in the primary dentition stage
Children able to cooperate during the photographic procedure
Children whose parents or legal guardians have provided written informed consent for participation and for the use of smile photographs
Disqualifiers
Photographs that do not comply with the standardized photography protocol defined in the study
Multiple photographs taken of the same teeth or the same tooth surfaces
Out-of-focus or blurred images
Images that are overexposed, underexposed, or taken under inadequate lighting conditions
Trial population
The study population will consist of adult participants aged 18 years and older, including dental students and parents attending the Department of Pediatric Dentistry for their children's routine dental treatment. Participants will evaluate digitally modified smile photographs representing different interdental spacing patterns and crown width discrepancies in primary dentition using a visual analog scale (VAS).

Perception of Smile Esthetics Assessed by Visual Analog Scale (VAS)
The esthetic perception of each digitally modified smile image will be evaluated by adult participants using a 0-100 mm visual analog scale (VAS), where 0 indicates "very unattractive" and 100 indicates "very attractive."
