3. Sickle Scalers
•Sickle scalers are designed for moderate to
heavy deposit removal.
•Specific sickle scalers are available for
anterior or posterior applications.
•They are mainly used to remove
supragingival calculus or subgingival
calculus, located just below the gingiva.
•2 Blade designs:
–Straight
–Curved

4. Sickle Scalers – Straight Blade
•Two cutting edges on a straight blade that
end in a sharp point.
•Also known as a Jacquette Scaler.

8. Sickle Scaler Instrumentation
•To remove calculus, adapt the tip 1/3 of the cutting edge
against the tooth, under the deposit. Tilt the facial surface of
the blade toward the tooth to achieve an approximate 85°
angle between the tooth and the blade.
•Apply lateral pressure against the tooth and pull the scaler
firmly upward to dislodge the deposit.

9. Sickle Scaler Instrumentation
•Both sides (cutting edges) of the blade can be used for
mesial or distal, facial or lingual application.
•The instrumentation sequence is the same as for universal
curettes, using anterior and posterior designs.
•Anterior sickle scalers have a straight shank compared to
the angled shank of posterior sickle scalers.
Anterior - Straight shank Posterior - Angled shank
