Jacquette designed a series of straight sickle scales, and as a result, a hygienist may use the term "Jacquette" to refer to a straight sickle scaler. Uses: This type of blade is excellent for broad facial and lingual surfaces, and can also be used interproximally.

In cross section, the blade of a scaler is triangular, whereas a curette is semicircular. The rounded, convex back of the curette allows it to be placed within a periodontal pocket with minimal laceration or discomfort to the patient.

Description. This scaler is used to remove plaque and calculus from the tooth surface. The sickle scaler tip can be used to remove calculus from the developmental grooves and blood grooves in canine teeth.

Sickle scalers are instruments used in periodontal therapy for removing calculus and plaque deposits from tooth surfaces. Commonly used to remove heavy calculus deposits and stains from the teeth, particularly in posterior regions where access is limited.
