Intraoperative Pain During Glide Path Creation with the Use of a Rotary or Reciprocating System

Objectives: The objective of this study was to compare the intraoperative pain levels of patients caused from using different glide path systems in creating the glide path before the root canal shaping the teeth with asymptomatic irreversible pulpitis. Materials and Methods: The study included 88 patient with asymptomatic irreversible pulpitis in mandibular molar tooth. The teeth were randomly assigned to four groups according to use of glide path files: R-pilot (RP), WaveOne Gold Glider (WOG G), One G (OG), Proglider (PG). In all the groups, the patients were asked to specify the pain level by using Visual Analogue Scale (VAS). Kruskall-Wallis and Mann-Whitney U was used to determine significant differences at p< 0.05. Results: In the present study, it was determined that the lowest intraoperative pain level was observed in PG, followed by OG, RP, and WOG G. Statistically significant differences were observed between PG and RP and between PG and WOG G groups (p<.05). Conclusion: All of the file systems used in creating the glide path in root canal treatment caused intraoperative pain. The minimum intraoperative pain was found with PG glide path file, whereas RP and WOG G caused higher level of intraoperative pain.
