Which instrument is specifically designed to remove subgingival calculus?

Scalpel
Curette
Explorer
Forceps

The correct answer is: Curette

The instrument specifically designed to remove subgingival calculus is the curette. Curettes have a rounded toe and a curved blade that allow for effective scaling and root planing procedures beneath the gum line. Their design enables dental professionals to access and clean areas that are often challenging to reach with other tools, thereby effectively removing deposits of calculus that accumulate below the gingival margin. In contrast, a scalpel is primarily used for cutting soft tissue and is not meant for calculus removal. An explorer is designed to detect caries and other irregularities on the tooth surface rather than removing deposits. Forceps are used to grasp or hold objects or tissue, but they do not have the specialized shape and function required for effective calculus removal. Thus, the curette is the appropriate choice for targeting and eliminating subgingival calculus buildup.
