Preserving primary teeth is essential for maintaining normal chewing, speech development, and psychological well-being. Successful pulpectomy depends on effective chemomechanical preparation of the root canals while preserving their original anatomy. Although hand files are traditionally used for canal preparation in primary teeth, they are time-consuming and may increase the risk of procedural errors. Nickel-titanium (Ni-Ti) rotary systems have gained popularity because they improve canal shaping and reduce instrumentation time. Among these systems, Pediatric NiTi rotary files manufactured with AF-H Wire technology and Pediatric NiTi rotary files manufactured with blue Wire technology are specifically designed for pediatric use. However, evidence regarding their clinical performance remains limited, highlighting the need to compare their effectiveness, particularly in terms of instrumentation time and obturation quality
