Summary

This study looked back at 126 patients who had gum regeneration surgery for severe gum disease. Researchers checked dental records and did a follow-up exam to see if the surgery helped close deep gum pockets and improve gum health. The goal was to understand how well these procedures work over time, not to test a new treatment.
