Abstract:
This work shows the results of mechanical strength tests effected over first superior bicuspids before endodontically treated. The Authors show the strength differences, in connection to the access-cavity, between endodontically treated and non-treated teeth. Finally it was found that the demolition of only one marginal ridge reduces the tooth strength to withstand the occlusal forces.
