The Analysis Study of Resistance to Cyclic Fatigue in Rotary versus Reciprocating Endodontic Instruments : A Comprehensive Systematic Review

Abstract

Background: Studies have shown that rotary instrumentation techniques are more effective in facilitating post-endodontic healing in the short term compared to manual methods. This systematic review aims to compare the cyclic fatigue resistance of rotary and reciprocating endodontic files. Methods: Following PRISMA 2020 guidelines, this systematic review focused exclusively on full-text articles published in English between 2014 and 2024. Result: The study conducted a comprehensive review of over 100 publications sourced from reputable databases, including ScienceDirect, SagePub, and PubMed. Following an initial screening, eight publications were identified as warranting more in-depth analysis. Consequently, a thorough review of these selected studies was performed to ensure a detailed and rigorous evaluation. Conclusion: The reciprocating files possess superior cyclic fatigue resistance compared to rotary files. Additionally, when tested in double curvature canals, reciprocating files exhibited enhanced resistance relative to rotary files.
