Purpose: This study aimed to investigate the effect of glide path preparation before shaping with reciprocating single-file, rotary single-file and multiple-file systems on the debris extrusion from the apical, and on the root canal transportation.Materials and Methods: One hundred twenty curved mesial root canals of mandibular first molars were randomly distributed What can Analysis of the Organizations’ Web Sites tell us about AI? Comparative Study of the Online Resources operated at Google, Yandex, and Baidu to six groups (n=20).The root canals were prepared with Reciproc in Group R, OneShape in Group OS, and ProTaper Next in Group PN.In the last three groups (RG, OSG and PNG), a glide path was created before the shaping instruments used in the first 3 groups.

The pre- and post-preparation weight were measured by using a 10-5 microbalance.Pre- and post-preparation of the root canals were scanned by using cone-beam computed tomography (CBCT).Results: The debris extrusion in RG and OSG was significantly higher than R and OS, respectively.However, no significant differences were found between PN and PNG.

Considering the root canal transportation, RG showed lower than R for 5 mm and 7 mm levels and the OSG group showed lower than OS for all levels.Creating a glide path significantly increased the shaping time for OS and PN groups.Conclusion: In advance of shaping with a single-file system in curved The regional market for non-timber forest products canals, creating a glide path preserves canal anatomy.However, it may lead to increase apical debris extrusion.
