Sybron endo m4 safety9/18/2023 ![]() ![]() 9,10 Systems like the ProGlider (Dentsply Sirona, Ballaigues, Switzerland), and G-Files (Micro-Mega, Besançon, France) are said to preserve the original canal anatomy and cause fewer aberrations and modifications of canal curvature. Mechanical (NiTi) glide path systems have been shown to improve the glide path prior to the use of NiTi shaping instruments. 6 Over the last few years, research has repeatedly shown that NiTi glide path rotary instruments are capable of achieving a safe and predictable glide path in comparison with hand files. 5 The use of hand files, however, has been shown to be more time consuming, particularly in teeth with constricted and/or severely curved canals. The glide path can be achieved with both hand- and rotary instruments. 2 Apical pre-enlargement tends to minimise biomechanical preparation failures such as canal transportation and ledge formation at different levels and also reduces the number of pecking motions required to achieve the working length. 1 A successful glide path is an uninterrupted passage that can be reproduced when small-size files are used in sequence in the canal. The endodontic glide path is defined as a smooth, patent passage from the coronal orifice of the canal to the radiographic terminus or electronically determined portal of exit. In this paper the authors discuss a review of the literature on some of these glide path techniques and illustrate the correct clinical application of some of these preparation techniques through clinical case studies. Many authors have proposed that rotary nickel titanium (NiTi) instruments should not be used for canal preparation without prior glide path preparation. Glide path enlargement allows for safer, more effective canal shaping with increased prospects of successful treatment outcomes. Maintaining a smooth, reproducible, glide path when successive files are used is an important characteristic of proper root canal preparation.
