Which instrument is typically used to remove supra-gingival calculus on anterior teeth?

• A. Sickle scaler
• B. Ultrasonic scaler
• C. Curette
• D. Files

Answer: (A)

Supra-gingival calculus on the crowns of anterior teeth is most efficiently removed with a sickle scaler because its design is specialized for cleaning above the gum line on smooth crown surfaces. The instrument features a rigid blade with a pointed tip and two cutting edges, aligned to make precise, short strokes that skim along the enamel and reach into interproximal areas without engaging deep pockets. This allows quick, controlled removal of deposits from the anterior teeth where visibility and access are favorable, while minimizing tissue trauma. Ultrasonic scalers can remove supra-gingival calculus as well, but they’re a different category of instrument that relies on vibrating tips and water spray. Curettes have a rounded toe and are more suited to subgingival work and root planing, making them less ideal for efficient supra-gingival cleaning on anterior crowns. Files are generally used to fracture large deposits rather than for routine supra-gingival scaling.
