Pulpectomy is the intervention of choice for treating infected pulp tissues in pediatric dental patients. Earlier this treatment was performed with hand instruments. Rotary instruments were introduced to pediatric endodontics in the year 2000. However, morphological challenges posed by the primary root canals demand an improvement in the quality and design of contemporary rotary instruments so as to avoid undesirable complications, viz., canal transportation, ledges, strip perforations, zips, etc.  Rotary NiTi files follow the original anatomy of curved canals in primary teeth, and hence minimize the risk of procedural errors. Also, a funnel-shaped canal preparation is obtained, and thus a uniform and more predictable obturation with pastes can be achieved. More importantly, rotary files shorten the preparation time considerably and, therefore, suit the shorter attention spans of children, thus, increasing their cooperation for the endodontic procedure. Recently reciprocating files system has been used in primary teeth for root canal preparation in primary teeth. So, it is necessary to evaluate the best system which results in successful pulpectomy procedure in primary teeth.
