Summary

This study tests a new ready-to-use root canal sealer (PA1704) against a standard sealer (BioRoot RCS) in 160 adults needing root canal treatment. The goal is to see if the new sealer works as well or better at keeping the tooth healthy and free of infection for up to 2 years. Participants will have follow-up visits at 6, 12, and 24 months to check the tooth's condition with X-rays and exams.
