Text messages may boost oral health in refugees
NCT ID NCT06649760
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This trial tests whether specially framed text messages can improve oral health and quality of life in refugees living in Alexandria, Egypt. Participants receive either gain-framed messages (highlighting benefits of good oral care), loss-framed messages (highlighting risks of poor care), or no messages. The study measures changes in dental plaque, gum health, and oral health-related quality of life over time.

- What this could lead to
- If effective, this approach could offer a low-cost way to improve oral health and quality of life in vulnerable refugee populations.
