Association Among Self-Reported Bruxism, Stress and Headache in a Sample of Adolescents: A Cross-Sectional Study.
Article in Journal of oral rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study evaluated the prevalence of self-reported awake bruxism and self-reported sleep bruxism among elementary and middle school students and its association with stress and primary headache.
methodsThree questionnaires were applied: questions about parafunction and behavioural habits for bruxism diagnosis, International Headache Society questionnaire for headache prevalence analysis, Lipp's inventory symptoms of stress (ISSL) for stress assessment. For the analysis of the data, the chi-square test was performed to compare proportions with 95% CI and the relative risk ratio test was also applied to study association with age and race. The level of significance was 5%.
resultsA total of 209 adolescents participated in the study. The prevalence was 3.8% for self-reported sleep bruxism, 8.13% for self-reported awake bruxism and 49.3% for bruxism, regardless of the frequency. There was an association among self-reported sleep bruxism, headache (p = 0.037) and stress (p = 0.000); self-reported awake bruxism, age (p = 0.024) and stress (p = 0.007); as well as similarly for the simultaneity of self-reported awake bruxism and sleep bruxism.
conclusionThere was also an association among stress, some symptoms of sleep bruxism and parafunctional and occupational habits. The findings suggest a significant association between self-reported sleep bruxism, self-reported awake bruxism, stress and self-reported headache.
