title: [Deformations occurring in the apical third of curved root canals during biomechanical preparation using manual impulsion-traction techniques].
abstract: Apical deformations, specially zips and elbows, during instrumentation of the root canals, are studied. The authors study why do they appear, their effect on endodontic therapy, and the way of avoiding them.
