A Novel Laboratorial Approach to Evaluate Bacterial Microleakage of Endodontic Sealers

Current Protocols, Volume 6, Issue 7, July 2026.
Abstract To avoid failure of endodontic treatment, it is important to properly seal the root canals after chemomechanical preparation in order to avoid microleakage. Typically, sealing involves the use of gutta‐percha and sealing cement, the latter of which adheres to the dentin and fills the spaces between the gutta‐percha and the dentin walls ...
