General characteristics :
- tapered
- straight
- millimeter calibration
- blunt, rounded tip
- thin ( 0,5 mm at the end )
- the shank is angled to allow easy insertion
in the pocket.

Sickle scaler
21. Function :
It is used primarily to remove supragingival calculus
Some sickle scalers are small , curved , thin enough
to be inserted a few mm below the gingiva .

22. Types of scalers
1)- Different blade size.
2)- Different blade design
curved, or straight .
3)- Different shank type :
- Straight shanks are designed
for use on anterior teeth
and premolars.
- Angled shanks adapt to
posterior.

Universal curettes
31. Gracey curettes are a set of several
instruments designed to adapt to specific
anatomic areas of the dentition.
The best instruments for subgingival scaling
and root planning because :
- they provide the best adaptation to
complex root surface anatomy.
- only one cutting edge, less damage to the
gingival soft tissues.

Area-specific curettes
( Gracey curettes )
32. 1. Blade is at 70 degrees from the lower shank
(offset blade). This angulation allows the blade to
be inserted in the precise position , provided parallel
lower shank with the long axis of the tooth surface
being scaled.

• They are modifications of the
standard Gracey curette
design. New features :
1. The terminal shank is 3 mm
longer ( allowing extension
into deeper periodontal
pockets of 5 mm or more).
2. A thinned blade . For
smoother insertion , and
reduced tissue stretching.
3. 1mm shorter blade

45. Function
Easier insertion and adaptation in any area
where root morphology or tight tissue
prevents full insertion of standard Gracey or

1. deep, narrow pockets,
2. furcations,
3. developmental grooves,
4. line angles,
