Association of parental oral health literacy, early childhood oral health behaviors, and caries severity with oral health-related quality of life among preschool children.
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 4 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
objectiveTo investigate the relationship between parental oral health literacy (OHL), children’s oral health behaviors and status, and oral health-related quality of life (OHRQoL) in preschool children, and to identify factors associated with OHRQoL.
methodsA convenience sampling method was used to survey 221 pairs of preschool children and their parents who visited the pediatric dentistry department from September 2023 to May 2024. Data were collected through questionnaires, clinical examinations, and validated scales—including the Chinese version of the short-form Health Literacy Dental Scale (HeLD-14) for OHL and the Early Childhood Oral Health Impact Scale (ECOHIS) for OHRQoL—to analyze relationships between sociodemographic characteristics, parental OHL, children’s oral health behaviors, oral health status, and dental caries severity with OHRQoL. Bivariate analysis, multiple stepwise linear regression, and hierarchical regression were performed to identify factors associated with preschool children’s OHRQoL.
resultsData from 206 children were analyzed. Parental OHL, children’s oral health behaviors, and oral health status were all significantly associated with OHRQoL in preschool children. Multiple stepwise regression analysis identified several independent factors associated with OHRQoL (P < 0.05), including parental OHL (β = -0.206, P = 0.001), age of starting toothbrushing (β = 0.164, P = 0.008), frequency of sweet food intake (β = 0.152, P = 0.013), caries severity (β = 0.199, P = 0.002), and history of toothache (β = 0.276, P < 0.001). Collectively, these factors accounted for 26.2% of the total variance in OHRQoL.
conclusionsOHRQoL in preschool children is associated with comprehensive factors, including family factors (parental OHL), oral health behaviors (age of starting toothbrushing, frequency of sweet food intake), and oral health status (caries severity, history of toothache). These findings suggest that strengthening parental OHL, implementing early oral hygiene interventions and limiting sugar consumption may be key strategies for improving OHRQoL among preschool children.
