A method of sealing a tooth's root canal using cyanoacrylate solution. A tooth undergoing endodontic treatment must have the pulp tissue removed and the canal cleansed and shaped. It then receives a coating of a cyanoacrylate solution to its walls. When hardened, this solution seals the dentinal tubules lining the walls of the root canal and lateral canals, when present, thus preventing communication from the canal to the periodontal membrane. When the apical foramen remains small, it also may be sealed to prevent the passage of fluids and microorganisms to the adjacent area. Including a component which renders the cyanoacrylate solution opaque to X-rays will permit examination throughout the endodontic procedure. The sealing solution may include methyl, ethyl, isopropyl, isopropyl alpha, or normal-butyl cyanoacrylate of medical grade purity.
