TruNatomy Niti Rotary Files: A Narrative Review of Their Potential and Limitations in Modern Endodontics

Abstract

This review critically evaluates the clinical performance of TruNatomy rotary files, a novel endodontic file system designed to optimize root canal preparation. The unique design and manufacturing process of TruNatomy aim to enhance flexibility, fatigue resistance, and cutting efficiency. While studies have demonstrated promising results in terms of dentin preservation, effective canal shaping, and high cyclic fatigue resistance, concerns have emerged regarding potential drawbacks.
Research has shown that TruNatomy may exhibit higher levels of debris extrusion and postoperative pain compared to some other rotary file systems. Additionally, its performance in complex canal anatomies may be limited by its lower buckling resistance. Although TruNatomy offers potential benefits, further comprehensive clinical studies are necessary to fully assess its long-term clinical performance, particularly in comparison to established rotary file systems. By evaluating the available evidence, this review aims to provide a balanced perspective on the clinical utility of TruNatomy and identify areas for future research.
