What instrument is used specifically for subgingival debridement?

The instrument specifically used for subgingival debridement is the curette. Curettes are designed to remove plaque, calculus, and debris from beneath the gum line, which places them in a unique position for effective cleaning in areas that require access to the subgingival space. They have a rounded toe and a curved blade that allows dental professionals to reach and efficiently clean root surfaces without damaging the surrounding tissue.

In contrast, while a sickle scaler is effective for supragingival scaling, its design isn't suitable for subgingival work due to its sharp end and straight blade, which could potentially harm the delicate gum tissue. An explorer is primarily used for detecting irregularities on the tooth surface, such as caries and calculus rather than for debridement. Forceps are primarily used for the removal of teeth and do not serve any function in scaling or cleaning subgingival areas.

Overall, the design and function of the curette make it essential for maintaining periodontal health through effective subgingival debridement.
