Smile Esthetics and Rotated Maxillary Lateral Incisors.
Article in International journal of dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: Although tooth rotations are a common orthodontic problem, little research has addressed how lay observers perceive these rotations. Consequently, the aim of this study is to determine laypersons' esthetic perceptions of changes in the rotation of the maxillary lateral incisors. Materials and Methods: An intraoral digital scan of a female adult's dentition was manipulated with ClinCheck software to create four smile conditions: (A) no rotation either maxillary lateral incisor, (B) 20° mesial-out rotation of both, (C) 30° mesial-out rotation, and (D) 40° mesial-out rotation. Each condition was shown with frontal and three-quarter view images. A panel of laypeople (age 18-30, no dental training) rated the attractiveness of each smile using a 100 mm visual analog scale (VAS; 0 = least esthetic, 100 = most esthetic). The score for each condition was recorded. A mixed-model two-way ANOVA (gender × rotation) with repeated measures was used to analyze the data. Results: No-rotation smiles were rated significantly more attractive than any smiles with rotated lateral incisors ( Conclusion: Laypeople preferred the smile with no rotation of the lateral incisors. They could not perceive a notable esthetic difference between 20° and 30° rotations. However, a 40° rotation was perceived as substantially less esthetic. Panelist gender did not affect esthetic ratings.
