[Obturation of curved canals: in vitro study of lateral compaction].

The instrumentation and filling of teeth with curved canals are always difficult, therefore, the current study indicates solutions to problems encountered while preparing curved canals. The gutta condensation techniques and their ability to seal curved canals are also discussed. This study uses endodontic simulators to show the incidence of protocols and instrumentation on the ability of the lateral condensation technique to fill curved canals. This study, also, evaluate the lateral condensation technique combined with the thermomechanical in filling curved canals.
