Dynamic navigation systems (DNS) have emerged as an innovative digital technology in endodontics, enabling real-time guidance during operative procedures. This review aims to critically evaluate the clinical applications and accuracy of dynamic navigation systems in endodontic practice. A comprehensive analysis of current literature was performed to assess the effectiveness of DNS in procedures such as access cavity preparation, location of calcified canals, guided endodontic microsurgery, and management of complex root canal anatomies. Evidence from in vitro, ex vivo, and clinical studies indicates that dynamic navigation systems significantly improve procedural accuracy, reduce deviation from planned pathways, and enhance the predictability of minimally invasive approaches compared with conventional freehand techniques. Additionally, DNS allows for greater flexibility than static guides, offering real-time feedback and adaptability during treatment. Despite these advantages, limitations such as high cost, learning curve, increased chairside time during the initial phase, and dependence on accurate imaging and calibration remain challenges to widespread adoption. Overall, dynamic navigation systems represent a promising advancement in endodontics, particularly for complex and high-risk cases. Further well-designed clinical trials are required to establish standardized protocols, long-term outcomes, and cost-effectiveness to support their routine clinical use.
