The relationship between malocclusion and speech patterns: a cross-sectional study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveDental occlusion and the alignment of the dentition play crucial roles in producing speech sounds. The Arabic language is specifically complex, with many varieties and geographically dependent dialects. This study investigated the relationship between malocclusion and speech abnormalities in the form of misarticulations of Arabic sounds. MATERIALS AND
methodsOne hundred native subjects (28.92 ± 12.09 years old) were recruited for this cross-sectional study. The Peer Assessment Rating (PAR) index was used to describe malocclusion pattern. A standard speech sample was recorded for each subject and evaluated by a blinded speech therapist to judge misarticulations and indicate the misarticulation classification. The Jeddah Institute for Speech and Hearing Centre (JISH) articulation test was used to assess the phonologic abilities of the participants. Mann-Whitney U test was utilized for the statistical analysis. P-value < 0.05 was considered statistically significant.
resultsThe PAR score ranged from 0 to 15, with an average of 4.87. The descriptive statistics of the included sample demonstrated that twenty-seven subjects showed improper articulation of sounds, with 25 being distortions and 2 substitutions. No significant gender differences were reported. A statistically significant association between PAR scores was recorded for the sounds / ص/ (p = 0.004), / ز/ (p = 0.017), and / س/ (p = 0.010).
conclusionsThere was an evident pattern of partial association of PAR index scores and speech abnormalities including improper articulation. To provide optimal care for involved subjects, collaboration between orthodontists and speech therapists, in pre- and post-treatment evaluations, is crucial.
