The s-shaped canal hands on protocol

Hands-on shaping: Managing s-shaped curvatures with WaveOne Gold instrumentation

Overview

This video demonstrates the practical application of WaveOne Gold reciprocating files to navigate a simulated tooth with an S-shaped root canal. It stresses the significance of releasing coronal interferences, utilising proper brushing techniques and strategically using transitional instruments.

Key topics covered

• Scouting the canal with a size 10 file
• The approach of softening the coronal curvature by brushing away from the curvature
• Active passes for instrumentation followed by irrigation
• Utilising the WaveOne Gold system, including the WaveOne Gold glider and small files
• Employing a brushing motion on the out-stroke to assist in coronal shaping
• Utilising files half a millimetre short of zero reading

Clinical relevance

The video illustrates how the concepts discussed in the schematic video are implemented clinically. It emphasises that the primary goal of coronal shaping is to allow for a straighter access to the middle and apical portions of the root canal. Time spent using the WaveOne Gold system pays off in an improved capacity to navigate the difficult apical curvature with lessened torsional fatigue.

Learning outcomes

• Dentists will be able to apply the concept of coronal curvature release using brushing techniques with a WaveOne Gold primary instrument
• Dentists will be able to correctly sequence WaveOne Gold files (glider, small, primary) to navigate complex curvatures
• Dentists will understand how to adapt their technique based on file progression
• Dentists will appreciate the importance of not forcing instruments, rather, using incremental steps and irrigation
