Rotary Endodontics in Pediatric Dentistry

Rotary endodontics in pediatric dentistry refers to the use of mechanically driven nickel-titanium (NiTi) rotary instruments for cleaning and shaping root canals in primary and young permanent teeth. Compared to traditional hand files, rotary systems provide faster preparation, improved efficiency, and more uniform canal shaping, which is especially beneficial in children with limited tolerance for long procedures. Their flexibility allows better navigation in curved or fine canals, reducing procedural errors like ledging or transportation. In primary teeth, rotary files help preserve root structure and minimize extrusion of debris, contributing to better prognosis of pulpectomy. They also shorten chairside time, which enhances cooperation and comfort for pediatric patients. However, careful case selection, operator skill, and understanding of the unique morphology of primary teeth are essential to avoid complications such as file fracture or over-instrumentation. Overall, rotary endodontics has become a valuable adjunct in pediatric practice, offering predictable outcomes and improved patient experience.
