Background: Mechanical preparation of a root canal system plays a key role in providing a successful and a more predictable endodontic treatment outcome. The intricate anatomy of root canals often poses a challenge for clinicians in aiding this objective. The preparation of a glide path provides a basis for effective cleaning and shaping, enabling all the subsequent instruments to move smoothly through the canal till the apical constriction, unhindered. A reproducible glide path enhances clinicians’ efficacy in understanding root canal anatomy, thus reducing the likelihood of procedural errors. Aim: This review article illustrates the importance of glide path preparation and also explains the numerous glide path instruments available over the years. Conclusion: Glide path is the key to radicular rotary safety. It is a pre-requisite to achieve the rationale of endodontics. Clinical Significance: Preparing a glide path increases the life span of rotary instruments, reduce the risk of procedural errors, providing the clinician a more detailed route map of the canal anatomy.
