What instrument is usually used to remove supra-gingival calculus?

The sickle scaler is specifically designed for the removal of supra-gingival calculus, which is the plaque and tartar build-up found above the gum line. This instrument features a pointed tip and a curved blade, allowing dental professionals to effectively engage and scrape away deposits from the tooth surfaces. The shape and sharpness of the sickle scaler make it particularly effective for accessing hard-to-reach areas and for performing more detailed cleanings.

On the other hand, while a scaler can refer to various types of instruments that assist in calculus removal, a curette is more suitable for subgingival cleaning, reaching below the gum line, and an excavator is mainly used for removing decay from teeth, not calculus. This specificity in design and use is what makes the sickle scaler the correct choice for supra-gingival calculus removal.
