Resin-Based Sealers

About resin-based sealers

An epoxy resin-based sealer for root canals comes as two pastes, an epoxide paste and an amine paste, which are mixed together. The epoxide paste is mostly calcium tungstate and zirconium oxide, and the amine paste adamantane amine and TCD-diamine. They are widely used for their physicochemical properties and antibacterial effect, but pushed into the tissue beyond the root they do not readily resorb and can bring about a short-term inflammatory response.

Two pastes mixed together, set by their own chemistry rather than by moisture.
