Summary

This study followed 130 adults with advanced gum disease (periodontitis) to see if those who used probiotics on their own during standard non-surgical treatment had better outcomes. Researchers measured plaque, bleeding, pocket depth, and quality of life at 1 and 3 months. The goal was to understand real-world probiotic use, not to test a specific product.
