What is a characteristic of a sickle scaler?

A sickle scaler is specifically designed for removing supra-gingival calculus, which is the hard dental deposits located above the gum line. It is characterized by its hooked or curved blade that allows for effective scaling of the tooth surfaces, especially interproximally and along the buccal and lingual surfaces.

The instrument often comes in pairs, with one scaler being a left-handed version and the other being right-handed, enhancing the dental hygienist's ability to access different areas of the mouth. This design characteristic makes it easier to manage various angles and surfaces of teeth during scaling procedures.

In contrast, a sickle scaler is not limited to one size; it comes in multiple sizes to accommodate different tooth surfaces and patient needs. While it might have some applications in slightly sub-gingival areas, it is primarily intended for supra-gingival use, making it less suited for deeper cleaning beneath the gum line. Furthermore, a sickle scaler does not feature a straight edge; its curvature is essential for its function in effectively scaling the teeth.
