Effect of malocclusion severity on oral health and its correlation with socioeconomical status in Iranian adolescents.
Article in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThis study aimed to assess the effect of malocclusion severity according to the Index of Treatment Need (IOTN) on oral health (dental caries and gingivitis), and its correlation with socioeconomic status (SES) in Iranian adolescents.
methodsThis descriptive cross-sectional study was conducted on adolescents between 10 and 16 years in Tehran city, who underwent clinical dental examination. The Dental Health Component (DHC) of the IOTN was used to assess the severity of malocclusion. The DMFT index was calculated to assess dental caries, and the gingival index (GI) was calculated for gingival health assessment. For oral hygiene assessment, the Oral Hygiene Index-Simplified (OHI-S) was calculated, and a questionnaire was used.
resultsTotally, 306 adolescents participated in this study. The frequency of IOTN grades was 88 (28.8%), 89 (26.1%) ,49 (16%), 60 (19.6%), and 29 (9.5%) for grades 1 to 5, respectively. The multinomial logistic regression showed that by an increase in OHI-S score, the odds of having IOTN grade 4 compared to grade 1 increased. Postgraduate parental level of education decreased the odds of having IOTN grade 4 compared to grade 1. Furthermore, there was an inverse correlation between oral hygiene practice and the odds of having IOTN grade 5 compared to grade 1.
conclusionsMalocclusion may hinder oral hygiene practice, and resultantly increase plaque accumulation. This risk may be amplified in children with lower SES, highlighting the need for preventive and educational oral health programs.
