Sickle Scaler
A hand-instrument with a triangular cross-section and two cutting edges meeting at a pointed tip, used for supragingival calculus removal.
Full Definition
The sickle scaler is a hand-scaling instrument characterised by its triangular cross-section, two sharp lateral cutting edges, and a pointed toe. Its design is optimised for supragingival and shallow subgingival scaling, particularly in anterior contact areas. Because of its rigid pointed tip, it is not suited for deep subgingival use, where gracey curettes are preferred. Editors reviewing instrument descriptions must ensure that sickle scalers are not described as suitable for deep subgingival work, as this is clinically inaccurate. Common sickle scaler designs include the Jacquette and the H6/H7.
Usage
Usage note: Clarify in clinical or educational text that sickle scalers are primarily supragingival instruments; describing them as interchangeable with curettes for deep subgingival scaling is an error.
