Abstract

It is in an increase trend recently as the tooth extraction caused with the root fracture. The condensation methods of root canal filling are paid attention as the potential cause of root fracture. The purpose of this experiment is to evaluate the influence that the condensation methods of root canal filling procedure relate to root fracture. It was experimented by using a suspected three dimensions photo-elastic model, and about the stress that breaks out on the inside of tooth and the periodontal tissues, when the root canal is pressed with the three kinds of spreader that is used to root canal filling.<br> The curved root was influenced to the stress between inside and outside of the root curve at the same tooth during root canal filling procedure. The complex root form of tooth had many stress points in its surfaces.
