This document summarizes a study conducted by the author to improve their own teeth brushing habits. It used a health belief model framework with a pre-test, intervention, and post-test approach. Video recordings were analyzed before and after receiving information on proper brushing techniques. Statistical analysis found significant improvements in flossing and brushing all surfaces of teeth after the intervention. The author learned concepts from the health belief model were high both before and after, but their self-efficacy did not guarantee accomplishments. They also learned to floss after brushing and store toothbrushes uncovered.
