Are childhood diseases associated with Molar-Incisor Hypomineralization? - Results from an observational study.
Observational study in Clinical oral investigations, 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 observational study aimed to investigate the potential association between reported childhood diseases and medications during early infancy and the later appearance of molar incisor hypomineralization (MIH). MATERIALS AND
methodsAs part of a prospectively designed epidemiological study, 5,418 Bavarian children aged 8 to 10 were examined for the presence of caries (WHO standard) and MIH (EAPD criteria). In addition, each child received a questionnaire to be completed by their parents. A total of 1,315 questionnaires were returned, containing complete information on childhood diseases, medication and socioeconomic status. Marginalized zero-inflated negative binomial regression models were constructed.
resultsA total of 263 children (20.0%) were diagnosed with MIH, with a mean of 3.3 (± 2.0) MIH-affected teeth. In cases of bronchitis (IRR 1.25 with 95% CI 1.07-1.46), otitis media (aOR 1.91 with 95% CI 1.30-2.80), eye diseases, allergies, speech disorders, worm infections and cardiac diseases, significant associations were found for the presence of MIH. In addition, a significant association between antibiotic use and MIH was confirmed (first year of life: IRR 1.45 with 95% CI 1.15-1.83; aOR 1.86 with 95% CI 1.13-3.05/second year of life: IRR 1.35 with 95% CI 1.05-1.77; aOR 1.36 with 95% CI 1.05-1.77).
conclusionsThe associations were mostly associated with low case numbers and accordingly cannot explain the documented MIH prevalence of 20.0%. Therefore, childhood diseases and antibiotic use probably do not solely contribute to MIH development. CLINICAL RELEVANCE: MIH aetiology remains unclear, indicating a need for further research.
