Curettes
Instrument of choice for removing subgingival
calculus, root planing altered cementum,
removing soft tissue lining.
Shows subgingival adaptation aroundthe root is best using a curette(instrument on right) as opposed to asickle scaler (on left).
*Note: Sickle scaler is not indicatedfor subgingival instrumentation

Two Types of Curette Designs:
2- Universal Curette1- Gracey Curette
-

17/30
Characteristics of the
Universal Curette Design:
Designed so that the working ends may be adaptedto all tooth surfaces of all regions of the oral cavitywith only one double-ended instrument.
The blade is honed at 90 degrees to the lower shank.
There is no curvature of the blade except for thecurve from the shank to the toe.
Has two cutting edges on each blade and both can
be utilized during instrumentation.

Characteristics of the
Gracey Curette Design:
Gracey curettes are area-specific instruments, with each bladeadapting to a specific tooth area or surface.
The blade of a Gracey curette is offset at an angle to the lower
shank.The shape of the blade is semicircular
The face of the blade is offset at about 70 degrees to thelower shank.
Has two cutting edges but, ONLY ONE cutting edge of the
Gracey curette blade is used.The rounded, convex back of the curette that allows its
placement into the periodontal pocket with minimallaceration or discomfort
Only the lower third or half of the blade contacts the root
surface during instrumentation.

Area Specific Curettes are the
GRACEY CURETTES:
Gracey 1-2 Anterior teeth
Gracey 3-4 Anterior teeth
Gracey 5-6 Anterior and bicuspid teeth
Gracey 7-8 Posterior teeth - buccal and lingual surfaces
Gracey 9-10 Posterior teeth -buccal and lingual surfaces
Gracey 11-12 Posterior teeth - mesial surfaces
Gracey13-14 Posterior teeth - distal surfaces

Sickle Scaler:
Hook-shaped instrument availablein various sizes and shapes
Flat blade cut at 90 degree angleto shank
Cutting edges on both sides of thefaceof the blade.
Functions primarily to removeSupragingivalcalculus

Anterior sickle
The blade , shank and handle are all in the same plane.
It is of two types;
Straight sickle and curved sickle

File Scaler:
Functions to crush tenacious
calculus
Used Supragingivally andSubgingivally

Hoe Scaler
Functions:To remove ledges or rings of calculus
Used Supragingivally and Subgingivally
Important to maintain a two-point contact with thetooth to stabilize the instrument
Used in a pull strokeonly blade is bent 99angle
Cutting edge has 45bevel

4- Ultrasonic and Sonic Instruments
Used for removing plaque,scaling, curetting, and removingstains
Alternating electrical current
causes scaler tip to vibrate whenadapted to the tooth
Attached water outlets at the tip
dissipate the heat generated by
the vibrationsThe cavitationcreated by the
water spray also helps flushdebris, calculus, and plaque
dislodged by the vibrations
