Abstract
A new root canal filling point which is physicochemically stable, is not toxic to periapical tissue, can be sterilized and x-rayed; and has high elasticity and fracture resistance which enables the root canal filling point to be pressure-inserted into an even narrow or curved root canal. The root canal filling point is made of a copolymer consisting of propylene and ethylene, and a contrast medium.
