Gamified oral health interventions (mobile apps, serious games, augmented reality, game-based education) vs Conventional or traditional oral health education, or non-gamified interventions (comparator varied; several studies were single-arm/uncontrolled)

Gamified interventions appear to improve oral hygiene behaviors (brushing habits, preventive dental visits) in children, but the evidence is narrative and ungraded.

  Post-intervention (predominantly short-term; long-term follow-up in a minority of studies) · School-based settings, specialized dental clinics, and home-based environments
  A gesture-based motion-capture game enhanced brushing independence and skill retention (P<.001) [Kang 2021]; 58.8% of caregivers reported their children brushed more often when using gamified applications [France…
