Endodontic treatment can be simplified by dividing the entire procedure into a series of smaller steps. The potential to consistently shape canals and clean root canal systems is significantly enhanced when the coronal two-thirds of the canal is first pre-enlarged followed by preparing its apical one-third.

In this Just-In-Time segment, conceptual discussions include:

• Simplifying the preparation
• Scouting the coronal two-thirds
• Shaping the coronal two-thirds
• Scouting the apical one-third
• Shaping the apical one-third
