First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether photodynamic therapy (PDT) — a light-activated disinfection method — can reduce pain after root canal treatment. 95 adults with infected back teeth received either standard cleaning or PDT-enhanced cleaning. Researchers measured pain levels and painkiller use over 72 hours. The goal was to see if adding light therapy makes recovery less painful.
