Clinical Trials 101 for the New Researcher

4.5 (2 votes)

Securing a reproducible glide path before instrumentation is recommended to maintain the original geometry of the root canal system and to prevent file separation. The aim of this study was to compare apical transportation, canal volume increase, and working time during glide path management with ProGlider (PG; Dentsply Tulsa Dental Specialties, Tulsa, OK) and PathFiles (PF, Dentsply Tulsa Dental Specialties).

At the conclusion, participants should be able to:

  • Discuss the importance of glidepath management in endodontics.
  • Describe the importance of using a non-destructive methodology for evaluating the file’s performance.
  • Evaluate the performance of two different glidepath systems with regard to apical transportation, volume increase and time required to achieve glidepath.
