Empowered Smiles Through Education and Motivation (e-SEM): A Theory-Driven Digital Oral Health Behaviour Intervention.
Article in International dental journal, 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
backgroundOral health conditions, particularly dental caries and periodontal diseases remain highly prevalent yet preventable global public health concerns. School-based oral health education can improve knowledge and behaviours, but traditional approaches often lack engagement and sustainability. Digital media offers an opportunity to deliver interactive, theory-driven, and culturally appropriate interventions. This study developed and validated empowered smiles through education and motivation (e-SEM), a digital oral health behaviour intervention for Filipino schoolchildren based on the information-motivation-behavioural skills (IMB) model.
methodsA methodological design was used in 3 phases: (1) elicitation through literature review and situational analysis; (2) development of culturally tailored digital materials including learning modules, animated storytelling, parent education content, and behavioural skills tools; and (3) expert content validation using Lawshe's Content Validity Ratio (CVR) and Content Validity Index (CVI), supplemented by qualitative feedback. Acceptability and usability were also assessed among parents and children using structured questionnaires.
resultsExpert validation demonstrated strong content validity across all components, with scale-level CVI ranging from 0.83 to 0.95. Digital learning modules and behavioural skills tools achieved the highest validity (CVI = 0.95), while animated storytelling videos showed comparatively lower scores (CVI = 0.83), indicating areas for refinement. Qualitative feedback supported the relevance and educational value of the intervention while highlighting the need to simplify language, improve pacing and enhance visual clarity. End-user evaluation showed high acceptability among parents (mean = 3.76/4.00) and high usability and engagement among children (mean = 2.77/3.00).
conclusionThe e-SEM programme demonstrated strong content validity and high acceptability, supporting its feasibility as a theory-driven digital oral health intervention for schoolchildren. Further refinement and effectiveness testing are recommended to evaluate its impact on oral health behaviours and outcomes.
