SEHAT Virtual Oral Health Promotion for School Adolescents in Pakistan

Официальное название

Evaluating the Impact of Novel Oral Health Promotion Program "SEHAT" Among Adolescents in Pakistan's Resource-Constrained Settings: A Cluster Randomized Trial

Обзор

The goal of this cluster-randomized trial is to learn if the SEHAT program works to improve oral health among school adolescents in Pakistan. It will also assess how the program affects oral health behaviors and knowledge. The main questions it aims to answer are: 1. Does the SEHAT program improve toothbrushing behavior and oral hygiene? 2. Does the SEHAT program reduce plaque and gingival scores among adolescents? 3. Does the program improve oral health knowledge and awareness? Researchers will compare the SEHAT virtual intervention with conventional oral health education and a control group to see which approach is most effective. Participants will: 1. Take part in either the virtual SEHAT session or conventional in-person oral health education, or receive no intervention (control) 2. Watch structured 30-minute sessions delivered via Zoom (virtual group) or classroom instruction (conventional group) 3. Participate in follow-up assessments to measure plaque, gingival indices, and oral health knowledge and behaviors.

Подробное описание

This study is a cluster randomized trial evaluating the effectiveness of the SEHAT (School-Based Education for Oral Health Awareness Using Advanced Telecommunication Technology) intervention among adolescents aged 11-14 years in public schools in Rawalpindi, Pakistan. The trial aims to improve oral health behaviors, knowledge, and clinical outcomes, including plaque and gingival scores.

Schools (clusters) will be randomly assigned to one of three groups: virtual SEHAT intervention, conventional in-person oral health education, or control (no intervention). The virtual intervention will deliver structured 30-minute sessions via Zoom, incorporating interactive elements, culturally relevant content, and reinforcement strategies, while the conventional group will receive the same content through face-to-face classroom instruction.

Outcome assessments will include clinical oral health measures (plaque and gingival indices) and self-reported oral health knowledge and behaviors, collected at baseline, post-intervention, and at follow-up timepoints to evaluate short- and medium-term effects. The study will also explore sustained engagement, feasibility, and acceptability of digital oral health education in resource-constrained school settings.

This trial addresses gaps in evidence regarding digital oral health interventions in low-resource settings, particularly for adolescents, and will provide data to guide scalable, culturally adapted, school-based oral health promotion strategies.
