sickle scaler

Question 1

used in the anterior region(of max and mand teeth) to remove supragingival calculus deposits

Answer 1

anterior sickle scaler

Question 2

anterior sickle scaler instrument design

Answer 2

-straight, rigid shank
-2 cutting edges on each working-end
-pointed tip (hence “sickle”)

Question 3

what third portion used for calculus removal on scaler

Answer 3

tip/toe 1/3

Question 4

when adapting, the shank and handle should be

Answer 4

parallel to the long axis of the tooth

Question 5

proper angulation of anterior sickle scaler (cutting edge against the tooth)

Answer 5

45-90 degrees

Question 6

over angulation will result in what
>90 degrees

Answer 6

burnished calculus and/or tissue laceration

Question 7

under angulation will result in what <45 degrees

Answer 7

burnished calculus

Question 8

what type of stroke
light grasp, minimal pressure (think perio explorer)

Answer 8

exploratory stroke

Question 9

what type of stroke
tighten grasp, apply lateral pressure to tooth on coronal stroke

Answer 9

working stroke

Question 10

operator positioning.

surface toward you:
surface away from you:

Answer 10

surface toward you:
left handed: 4

surface away from you:
left handed: 12-1

Question 11

same as anterior scaler, but with a bend in the shank (complex design) for access in the posterior region

Answer 11

posterior sickle scaler

Question 12

the posterior sickle scaler is meant to scale

Answer 12

interproximal regions of posterior teeth

supragingival [and subgingival if happen to be some spurs}

Question 13

with posterior sickle scaler, the terminal shank is ____to the long axis of the tooth and you insert at the ______then scale into interproximal

Answer 13

parallel

line angle

Question 14

what areas do you not scale with posterior sickle scaler

Answer 14

buccal and lingual surfaces!!
