Summary

This study tests three different mouthwashes (chlorhexidine, cetylpyridinium chloride, and essential oil) in 24 people with braces to see which one reduces plaque and gum inflammation best. Participants will try each mouthwash for a week, with breaks in between. The goal is to find the most effective and patient-friendly option for keeping teeth and gums healthy during orthodontic treatment.
