Mind over mouth: could changing beliefs lead to better brushing?
NCT ID NCT07715773
First seen Jul 20, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This trial tests whether a program based on the Expanded Health Belief Model can help college students stick to good oral health habits like brushing and flossing. About 166 students aged 18 to 25 will be randomly assigned to either attend awareness lectures or receive no extra guidance. Researchers will measure changes in students' attitudes, motivation, and intentions toward oral care to see if the program works.
