1

Assessment strokes are

light, feather-like long overlapping strokes

2

*Debridement strokes

moderate shaving strokes

3

*Calculus Removal strokes are

firm, short, biting strokes

4

3 types of calculus removal instruments

Area specific curets-toe
Universal curets-toe
Sickles-triangle

5

What 2 surfaces form the cutting edge

Face and lateral surfaces

6

What is the terminal shank at in relation to parallel tooth without adapting for
sickle scaler
universal curet
area-specific curet

sickle scaler and universal curet is at a 90 degree relation
and the area-specific is already at 70 degree angel for adatption

7

What degree is needed to adapt for sickle scaler and universal curet

60-70 degree

8

• Specific instruments designated for
anteriors and posteriors
• All designed for all surfaces
• All designed for supra/slightly subgingival
use on ENAMEL ONLY
• Standard/ rigid shank- removal of medium
to large size deposits
• Lower shank must be slightly angled
towards the tooth surface to establish
proper angulation

Sickles

9

Can a sickle scaler be used on posteriors

yes

10

Can a sickle scaler be used on root surfaces

NO only enamel. it can slightly go subgingival though

11

Sickle Anterior should have the shank leaning ___ surface using toward.

toward

12

• All designed to be used in the anterior and
posterior
• All designed for all surfaces
• All designed for supra and subgingival use
• Standard shank is normally more rigid
than the standard shank of an area-
specific curet
• Lower shank must be slightly angled
towards the tooth surface to establish
proper angulation

Universal Curets

13

Terminal shank ___ with long axis for correct working end for universal curet

parallel

14

universal curet: 1 double ended instrument can be used for appiclation for all anterior or posterior teeth

posterior

15

• All designed for supra and subgingival use
• Two instruments are required to complete
each aspect of a posterior tooth.
• One instrument is required to complete
each aspect of an anterior tooth, but you
will use both ends of the instrument. What
other instrument do you use this way?
• Standard shank is flexible- removal of
light/moderate calculus.
• Lower shank is parallel to tooth surface to
establish proper angulation

Area specific curets

16

1 instrument used for D
surfaces. 1 instrument used for B/L and M surfaces

site specific

17

a. Gracey 1/2-5/6
b. Gracey 7/8 -9/10

GRACY 1/2-5/6

18

anterior teeth all
surfaces (crowding) posterior line angle to line angle

a. Gracey 1/2-5/6
b. Gracey 7/8 -9/10

gracey 7/8-9/10

19

Posterior teeth facial, lingual and mesial surfaces

a.Gracey 11/12
Gracey 15/16

b.Gracey 13/14
Gracey 17/18

a.

20
