Quick Reference

A single-visit endodontic technique that uses formaldehyde as a mummification agent. 5% formaldehyde is added to a zinc oxide root canal sealer. It is also known as the Sargenti technique. Serious concerns have been raised concerning this technique since formaldehyde is known to cause permanent tissue damage if not confined to the pulp chamber or root canal system.
