Creating a safe and reproducible glide path is one of the most critical steps in modern endodontic treatment. An inadequate glide path increases the risk of instrument separation, canal transportation, and inefficient shaping.
While traditional stainless steel hand files remain widely used, newer mechanical solutions—including the M4 handpiece and NiTi glide path systems—have introduced alternative strategies that may improve efficiency and predictability.
This lecture will explore the biological and mechanical principles of glide path preparation while comparing the use of M4-assisted stainless steel files and contemporary NiTi glide path systems. Through clinical insights, case examples, and practical guidelines, participants will learn how to select the appropriate glide path technique based on canal anatomy, calcification, and treatment goals.
After completing this course, participants will be able to:
- Explain the importance of glide path preparation in preventing instrument fracture and maintaining original canal anatomy during rotary instrumentation.
- Compare the advantages and limitations of M4-assisted stainless steel files and NiTi glide path systems in different clinical scenarios.
- Identify appropriate case selection criteria for choosing between stainless steel and NiTi glide path strategies.
- Apply practical clinical tips to safely and efficiently establish a predictable glide path in narrow, curved, or calcified canals.
