Comparative Assessment of Smile Attractiveness Perception and Treatment Need Across Dental Professionals and Laypersons.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSmile esthetics are crucial in orthodontics; however, orthodontists, general dentists, and laypersons perceive deviations differently, prompting the need for comparative evaluation. This study explored how these groups assess upper midline discrepancies, gingival display, maxillary cant, reduced upper teeth show, asymmetric upper lip elevation, and chin deviation, aiming to determine their combined impact on smile attractiveness and treatment needs while identifying thresholds for clinical intervention to enhance patient-focused care. METHODOLOGY: This cross-sectional study was conducted in the Department of Orthodontics from August 2023 to October 2024. A frontal smile photograph was digitally manipulated to create six series of images (54 images), each with nine variations of upper midline displacement with respect to facial midline (-2 to +2 mm in 0.5 mm increments). Modifications included increased gingival exposure (gumminess), a 5° maxillary cant, reduced upper teeth show, 2 mm asymmetric upper lip elevation, and 2 mm chin deviation. Ninety evaluators (30 orthodontists, 30 general dentists, 30 laypersons) assessed the images using a visual analog scale (VAS) for attractiveness and indicated the need for treatment. Data were analyzed using one-way analysis of variance (ANOVA) for VAS scores and chi-square tests for treatment need, with intra-evaluator reliability assessed using intraclass correlation coefficients.
resultsOrthodontists demonstrated significantly higher sensitivity to minor upper midline deviations (-1.0 mm to 0.0 mm), maxillary cant, and asymmetric upper lip elevation compared to general dentists and laypersons (
conclusionsProfessional expertise significantly influenced the detection of subtle smile deviations, with orthodontists advocating treatment more often than laypersons. These findings emphasize the need for tailored patient communication to align clinical interventions with patient expectations and enhance patient-centered orthodontic outcomes.
