The Effect of Glide Path Preparation on Root Canal Shaping Procedures and Outcomes.

Microcomputed tomography analysis of curved root canal preparation when coronal flaring and glide path files used with heat-treated nickel titanium rotary files

“…This technique requires the clinicians to establish straight-line access to the mid-root to allow free access to the curvature in the coronal third [ 5 , 6 ]. A further recommendation was to use small K-files in sequence to the root terminus to create a glide path for larger rotary NiTi files [ 8 , 14 , 15 ]. The glide path is a crucial step to prevent blockage of the curved root canal system.…”

“…The glide path is a crucial step to prevent blockage of the curved root canal system. Since motor-driven rotary NiTi files are more efficient in creating the glide path, in comparison to manual K files, small-sized glide path rotary files were developed [ 8 , 14 , 15 ]. These files can be used after size 10 K files and before the use of rotary file systems [ 8 , 14 , 15 ].…”

“…Additionally, excessive removal of dentin at the cervical region will weaken the root structure rendering it susceptible to fracture [ 10 ]. The glide path rotary files were advised to use especially in curved root canals to reduce procedural errors such as ledging and file breakage [ 14 , 15 ]. The advantage of their use in addition to the modern highly flexible heat-treated NiTi rotary files is questionable [ 14 , 15 ].…”

The advantage of their use in addition to the modern highly flexible heat-treated NiTi rotary files is questionable [ 14 , 15 ]. Moreover, dynamic irrigation is intended to improve irrigation penetrative and lubricant ability reducing the need for excessive flaring or sequential use of rotary files [ 4 ].…”

Influence of Different Glide Path Techniques on Microcrack Formation after Two Different Root Canal Preparation Treatments: Micro Computed Tomography Analysis

“…A glide path is a regular opening that extends from the orifice of the root canal to the apical foramen. Creating a glide path is important for root anatomy evaluation to provide an unobstructed path that thus reduces the torsional stress on the dentine wall, thereby reducing the incidence of root crack formation ( 11 , 12 ). Many rotary path-finding systems are also available, including the TruNatomy Glider (TRNG), which has a centred and parallelogram-shaped cross-section made from post-manufactured heat-treated NiTi alloy ( 11 ).…”
