Summary

This study tested whether taking omega-3 or vitamin D supplements daily helps treat gum disease (periodontitis) better than standard deep cleaning alone. 72 adults with moderate gum disease received either omega-3, vitamin D, or no supplement alongside their dental treatment. Researchers measured gum attachment loss and plaque buildup over 6 weeks to see which approach worked best.
