[Biocem--a new material for retrograde tooth root filling].

This paper describes the application of a new material, Biocem, for retrograde root-canal filling. The series included 222 teeth, including 234 roots treated during the period 1987-1992. This material consists of two components and once mixed, the autopolymerisation results in a three-dimensional structure. The biomechanical, histological and clinical longterm follow-up confirms the optimal qualities of this material, fulfilling the requirements in regard to biocompatibility, watertight sealing and application. The material proved to be superior in comparison to conventional materials and ceramics. The significant reduction of complications and the new apposition, as well as the evaluation of the results are most encouraging.
