What dental instrument is specifically designed for the removal of subgingival calculus?

The curette is specially designed for the removal of subgingival calculus, which is tartar located below the gum line. Its distinctive shape and angled blade enable dental professionals to access deep periodontal pockets where subgingival deposits accumulate. The rounded tip of the curette minimizes trauma to the surrounding tissues, allowing for safe and effective scaling of calculus without damaging the gums.

This instrument typically has a sharp cutting edge that is curved, facilitating the scraping action needed to detach calculus from tooth surfaces in hard-to-reach areas. In periodontal treatment, the curette plays a crucial role, as removing these deposits is vital for maintaining periodontal health and preventing progression of gum disease.

In contrast, while instruments such as sickle scalers are designed for supragingival calculus removal, and explorers and probes serve diagnostic functions, they are not intended for the specific needs of subgingival calculus removal. Therefore, the curette is the optimal choice for this task.
