Summary

This study tested a chlorhexidine varnish applied to teeth in people with braces. Each person's mouth was split: one side got the active varnish, the other a placebo. Over 3 months, researchers measured gum overgrowth, plaque buildup, and early tooth decay (white spots). The goal was to see if this simple coating could prevent common orthodontic side effects.
