What is the primary function of a scaler in periodontal care?

The primary function of a scaler in periodontal care is to remove heavy calculus from the tooth surfaces. Scalpers are specifically designed with sharp edges that allow dental professionals to efficiently access and remove deposits of calculus, also known as tartar, that may accumulate on both supragingival (above the gum line) and subgingival (below the gum line) surfaces. Effective calculus removal is crucial for reducing irritants that can lead to inflammation and periodontal disease.

While root smoothing and subgingival scaling are important aspects of periodontal treatment, they are generally performed with other instruments like curettes that are designed for those specific tasks. Mouth rinsing does not involve a scaler and serves a different purpose, often pertaining to antimicrobial effects or patient comfort rather than actual mechanical removal of calculus. Therefore, the most accurate choice reflecting the primary function of a scaler is its role in the removal of heavy calculus.
