Question 1

What are the 4 types of manual scalers?

Answer 1

Mini sickle (point)
Colombia (universal)
Hoe
Gracey Curette

Question 2

What is the mini sickle used for?

Answer 2

used to remove supra-gingival calculus from buccal and lingual embrasure surfaces
sharp therefore should not be used subgingivally

Question 3

What is the colombia used for?

Answer 3

semi-circularcurved blade with two cutting edges
used for upper/lower anterior teeth
supra/sub gingival removal

Question 4

What are the different types of hoe used for?

Answer 4

cutting edge is bevelled
134-135 yellow is used for buccal/lingual large calculus deposits
156-157 red is used for mesial/distal large calculus deposits

Question 5

What are the different graceys used for?

Answer 5

Gracey Curette 1-2 (grey) -
Designed for fine/deep sub- gingival scaling of upper and lower anterior teeth.

Gracey Curette 7-8 (green) -
Designed for fine/deep sub- gingival scaling of buccal/lingual surfaces of posterior teeth.

Gracey Curette 11-12 (orange) -
Designed for fine/deep sub- gingival scaling of mesial surfaces of posterior teeth.

Gracey Curette 13-14 (blue) -
Specifically designed for fine/deep sub-gingival scaling of the distal surfaces of posterior teeth.

Question 6

What are the seating postions for a right-handed operater?

Answer 6

7-11 o’clock

Question 7

What are the motions used for scaling?

Answer 7

no flicking, controlled motions that aim to bring calculus to the tip of the tooth

Question 8

How do you identify the cutting edge of a gracey?

Answer 8

blade should be face up and parallel to the floor
the outer, lager curve is the cutting edge

Question 9

Why should instruments be sharpened regularly?

Answer 9

for more efficient root planing and less time wasted

Question 10

How do you avoid a sharps injury when using ultrasonic scalers?

Answer 10

do not leave scaler upright

Question 11

How much of the terminal shank should be used to debride?

Answer 11

2mm

Question 12

What is the required angulation of the terminal shank?

Answer 12

0-15 degrees

Question 13

What are the standard inserts and when should they be used?

Answer 13

CAVITRON
FSI 10 - moderate/heavy sub/supra gingivally
FSI 100 - moderate/heavy posterior teeth (double bend tip) subsupra
FSI 1000 - moderate/heavy line angles and interproximal (triple bend tip) sub/supra
FSI 3 Beavertail - calculus bridges, stains, heavy deposits, (blunted tip) supra only

Question 14

What are the slim inserts and when should they be used?

Answer 14

CAVITRON Slimline
FSI 10 - light/moderate calculus crown to margin
FSI 1000 - triple bend, bevelled edges
FSI R/L Curve - used for debridement in pockets >4mm, furnications and cavities. reach under contact points supragingivally

Question 15

What are the speciality inserts and when should they be used?

Answer 15

CAVITRON
FSI thinsert - provides access to difficult areas such as misalignment, areas of tight contact, and interproximal surfaces
Softtip implant - removes plaque/calculus without damaging titanium abutment surfaces, used with a disposable tip
