Recent technological advances and clinical demands have led to an overwhelming fabrication and production of various types of rotary instruments. Most rotary file designs follow general principles that determine their characteristics, such as flexibility, strength, efficiency, and fracture resistance. This presentation will explore these general principles from a historical angle and introduce a practical and easy-to-follow classification for rotary files based on their characteristics. This lecture will also provide a few physical features of rotary files that clinicians can swiftly identify to determine these characteristics, especially the one involving fracture resistance.

Learning Objectives:

  • List different types of rotary files in terms of design and metallurgy.
  • Provide a few examples of how file design can affect clinical performance.
  • Demonstrate how file selection can assist in the prevention of separation during treatment.
