How can you identify the cutting edge of a Gracey curette?

Identifying the cutting edge of a Gracey curette is essential for effective periodontal treatment. The correct method involves holding the curette vertically with the toe facing towards you. This orientation allows for a clear view of the blade's orientation relative to the tooth surface.

In this position, the curvature of the instrument can be visualized, and it becomes evident which edge is sharp and designed for cutting. The toe of the curette is where the cutting edge is located, and by ensuring it faces you, the clinician can align the instrument correctly against the tooth surface for effective scaling and root planing.

This method is particularly important in periodontal procedures where precision is crucial for removing calculus and debris from specific areas of the tooth, especially subgingivally. Thus, holding the instrument in this manner is the most effective way to ensure that the cutting edge is utilized properly, improving both efficacy and safety during treatment.
