Which instrument is best suited for removing subgingival calculus?

The Gracey curette is specifically designed for the removal of subgingival calculus due to its unique features. It has a curved blade that allows for easier access to the root surfaces of teeth below the gum line. The blade is set at a specific angle that enables effective scaling and root planing in deep periodontal pockets. The design facilitates effective adaptation to tooth surfaces, ensuring that calculus is removed efficiently while minimizing trauma to the surrounding soft tissue.

In contrast, while the periodontal hoe can be useful for supragingival scaling, it is not ideally shaped for accessing the contours of roots that are below the gumline. The ultrasonic scaler is effective for both supragingival and subgingival scaling, but it may not provide the precision and tactile feedback that manual instruments like the Gracey curette offer, especially in more delicate and challenging areas. The dental explorer is predominantly used for detecting caries and assessing tooth surfaces rather than for removing calculus. Hence, when it comes to targeted subgingival calculus removal, the Gracey curette stands out as the most suitable instrument.
