What is a sickle scaler used for?

For the removal of supragingival calculus.

What is a periodontal hoe scaler used for?

For the removal of supra- and subgingival calculus. Suitable for deep, narrow pockets and concave root surfaces. For both vertical and horizontal techniques.

Is a nevi a sickle scaler?

The Nevi 2 is a super thin posterior curved sickle scaler. The unique contra-angle design is great for interproximal reach and ergonomic hand positioning. The Nevi 4 Posterior Scalers are tapered dual cutting blades that provide precise access for effective deposit removal.

What is the difference between a scaler and a curette?

The major difference between the design of a scaler and a curette is in the shape of the blade. In cross section, the blade of a scaler is triangular, whereas a curette is semicircular. Area-specific curettes, such as the Gracey curettes, are designed so that each blade adapts to a specific tooth surface or area.

What do scalers have?

Scalers have scraping edges on both sides of their blades and thus are fit for both mesial and distal surfaces of any tooth in the area in which they are being used.

Why are scalers used?

Initially ultrasonic scalers were used to only remove calculus deposits on tooth surfaces visible in the mouth, but they can also be used sub-gingivally, meaning they can remove calculus deposits from just below the gum line, cleaning the surfaces of tooth roots without damaging them.

What is the difference between a sickle scaler and a curette?

The major difference between the design of a scaler and a curette is in the shape of the blade. In cross section, the blade of a scaler is triangular, whereas a curette is semicircular. Only one cutting edge on each blade is used.

How do you use a sickle scaler for dental work?

Tilt the instrument toward the tooth to achieve 70° to 80° angle between the tooth and the blade. Apply lateral pressure and activate the scaler by using vertical, diagonal or horizontal pull strokes. To maintain control use short 2-3 mm long strokes.

How do you use a sickle scaler to remove calculus?

For the removal of supragingival calculus. For calculus removal place the tip third of the scaler’s cutting edge against the tooth. Tilt the instrument toward the tooth to achieve 70° to 80° angle between the tooth and the blade. Apply lateral pressure and activate the scaler by using vertical, diagonal or horizontal pull strokes.

What does the handle of a periodontal instrument do?

The handle of the instrument is used for grasping the instrument. Shank connects the handle to the working end and allows adaptation of the working end on the tooth surface. The working end does the work of the instrument.

How are calibrations made on a periodontal instrument?

Calibrations in millimeters are made at various intervals, facilitating measurement of periodontal pocket depths. The working end of the probe may be curved to facilitate probing into the furcation areas.
