Comparative Evaluation of Apical Debris Extrusion in Primary Molars Using Three Different Pediatric Rotary Systems: An Study.

Aims And Background: Failure of the endodontic treatment might be due to various reasons like zipping, apical blockade, ledging, debris extrusion, etc. Apical debris extrusion in primary teeth is of major concern as it does not have a proper well-developed apex, that is, mature apex. This study aims to compare and evaluate the apical debris extrusion in primary molars using three different pediatric rotary file system.
