Summary

This study tested if a special light device used at home can help manage chronic periodontitis, a serious gum infection. 202 adults with gum disease used the device regularly to see if it reduced bleeding and improved gum health. The goal was to offer an easy, non-invasive way to control the condition alongside standard care.
