First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether heating sodium hypochlorite (a common disinfectant) inside root canals of dead teeth can kill more bacteria and reduce pain afterward. Thirty-six adults with a single dead tooth will receive one of two heating methods or standard cleaning. Researchers will measure bacteria levels before and after treatment and ask about pain levels.
