At present, the gutta percha point and the sealer are used at the rate of 70～80% as materials for filling a root canal on the terminal treatment of endodontics.
The authors developed a new sealer for filling a root canal and comparative tests were performed with the existing sealer on the market.
Samples were filled in glass tubes and extracted teeth and the sealing ability which is the most important physical property for the sealer to fill a root canal was examined by the test of dye solution permeation.
As a result of the tests, we have following information,
1. The Pulp Canal Sealer has poor sealing ability which is different from the report of Grossman L.I,.
2. The sealing ability of the sealer of eugenol system is poor.
3. GP sealer the authors developed and Sealapex on the market indicate good value.
