School-based First Aid Education for Dental Trauma Awareness: A Scoping Review

Traumatic dental injuries (TDIs) are frequent in children. Schools provide a strategic platform for delivering dental trauma education, yet the nature and effectiveness of such interventions remain underexplored. To map existing evidence on school-based educational interventions designed to improve awareness and management of TDIs. Following the Joanna Briggs Institute methodology and PRISMA-ScR checklist, studies published between January 2000 and August 2025 were reviewed. Eligible designs included randomized controlled trials, quasi-experimental studies, and pre–post evaluations. Data were extracted on participants, interventions, outcomes, and implementation factors. Eleven studies conducted across Hong Kong, Brazil, Iran, Lebanon, Syria, and India met the inclusion criteria. Interventions targeted teachers ( n = 7), students ( n = 3), or school staff ( n = 1). Modalities included posters ( n = 5), lectures ( n = 4), leaflets ( n = 3), digital videos ( n = 2), and multimodal packages ( n = 2). Reported knowledge improvements ranged from 30% to 45% immediately post-training, especially for avulsion management and correct storage media. Knowledge retention declined over time, though periodic reinforcement (e.g., poster display or repeated sessions) enhanced long-term outcomes. Multimodal interventions achieved the most durable effects. School-based interventions consistently improve knowledge of TDI management among teachers and students by up to 45%. Integrating dental trauma education into school health curricula, supported by policy endorsement and periodic reinforcement, could optimize emergency preparedness in schools and strengthen emergency preparedness in schools.
