Abstract

A method of filing an endodontically prepared root canal includes the steps of applying filler material to a distal portion of an elongated shaft formed of heat conducting material, inserting the proximal portion of the shaft having the filler material thereon into the root canal, heating the shaft to decrease the surface tension of the filler material and removing the shaft leaving the filler material in the root canal. An obturator system for practicing the method of filling an endodontically prepared root canal employs an elongated heat conductible shaft having proximal and distal portions with filler material on the distal portion, the distal portion of the shaft with the filler material thereon being insertable into a tooth root canal and a heat source serving to selectably heat the shaft allowing it to be removed while leaving the filler material in the root canal.
