What this trial studies

This clinical trial evaluates the effectiveness of two health education interventions aimed at preventing dental caries and gingivitis in patients undergoing orthodontic treatment. It compares a conventional oral health education approach with a motivational interviewing strategy to encourage sustainable behavioral changes in oral hygiene practices. The study will involve 94 participants aged 13 to 28, who will be monitored over six months for changes in oral health outcomes. Assessments will include the presence of gingivitis, caries, and adherence to the interventions at multiple follow-up points.

Why it matters

Potential benefit: If successful, this study could lead to improved oral health outcomes and reduced incidence of dental caries and gingivitis in orthodontic patients.

How similar studies have gone: Previous studies have shown that motivational interviewing can be effective in promoting health behavior changes, suggesting potential success for this approach.
