Influence of facial pattern on the aesthetic assessment of the inclination of the occlusal plane in the frontal view.

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
objectivesThe aim of this study was to analyse the aesthetic perception by orthodontists, dentists and laypeople of the different inclinations on the occlusal plane in the frontal view in relation to facial biotype. MATERIALS AND
methodsThe three groups of assessors evaluated the aesthetics of images with occlusal plane inclinations of 0º, 2º and 4º in a mesofacial, dolichofacial and brachyfacial face. Scores were assigned from 1 to 10 ("1": poor aesthetics and "10": very satisfactory aesthetics). The data were evaluated by the Kruskal-Wallis test (p < 0.05) and the Mann-Whitney test (Bonferroni correction p < 0.016).
resultsIn meso- and dolichofacial faces, orthodontists considered 0º occlusal plane inclination to be significantly more aesthetic than 2º (mesofacial p = 0.004, dolichofacial p < 0.001) and 4º (p < 0.001), and 2º inclination more than 4º (p < 0.001). Dentists and laypeople rated 0º and 2º inclinations as significantly more aesthetic than 4º (p < 0.001) with no significant differences between 0º and 2º inclinations. For the brachyfacial face, the three groups rated 0º and 2º occlusal plane inclination as significantly more aesthetic than 4º inclination (p < 0.001), with 0º and 2º inclinations scoring similarly (p > 0.016).
conclusionsOrthodontists were more critical than dentists and laypeople when assessing mesofacial and dolichofacial facial types, whereas no differences were observed between the three groups for brachyfacial faces. CLINICAL RELEVANCE: The facial pattern influences the perception of the occlusal plane. Understanding these differences is crucial for clinicians, as it can enhance diagnostic accuracy and optimize treatment planning, leading to more personalized and effective orthodontic care.
