What instrument is best for removing subgingival calculus in a Class II furcation?

The Gracey curette with an extended shank is ideal for removing subgingival calculus in a Class II furcation due to its design, which allows for better access and adaptation to the curved and complex anatomy found in these areas. The extended shank enables the clinician to reach deeper into the furcation without damaging the surrounding tissue, making it effective for scaling in areas that are challenging to access. Additionally, the Gracey curette is specifically designed for subgingival use, with a blade that is set at a specific angle to facilitate effective calculus removal.

In a Class II furcation, where the roots are partially separated, the curvature and the location of the calculus often require instruments that can navigate these anatomical complexities. The blade design of the Gracey curette allows for a more efficient and effective scaling process, contributing to improved periodontal outcomes for the patient.
