Answer 10

Maxillary upward

Mandibular downward

2mm constant contact with tooth

Question 11

Most effective manner to position explorer for max 1st premolar. What strokes?

Answer 11

Tip up and horizontal strokes

Question 12

Direction to explore a concavity

Answer 12

M to D

Question 13

What instrument is recd to instrument roots of multi rooted teeth ?

Answer 13

Mini area specific gracey curet

Question 14

Treat each root branch as a single rooted tooth?

Answer 14

Yes distal to mesial

Question 15

Which instrument is furcation area cleaned by?

Answer 15

Mesial gracey
(Possible board question)

Question 16

What strokes are used to remove deposits from root concavities and depressions

____ strokes are not effective bc the working end “spans across” root concavity, missing the deposit

Answer 16

Horizontal

Vertical not effective

Question 17

Can the gracey 11 be used for horizontal strokes?

Answer 17

No just vertical

Question 18

What position for gracey 12? Toe, fulcrum

Answer 18

Toe down , fulcrum down

Question 19

Is the correct working end to make a vertical stroke on the mesial surface the same working end to make a horizontal stroke on that same surface ?

Answer 19

NO

Question 20

Distal surfaces
G13 used for vertical what is used for horizontal?

Mesial surfaces
If G11 used for vertical strokes what is used for horizontal

Answer 20

G 14

G12

Question 21

Is the same working end used to make vertical and horizontal strokes on FACIAL AND LINGUAL?

Ex. G 12 on both f and l

Answer 21

Yes

Question 22

The standard fulcrum places the least amount of strain on clinicians fingers and should not be replaced by advanced techniques

T or F

Answer 22

True

Question 23

When should advanced fulcrums be used ?

Answer 23

Narrow deep perio pockets (distal 3rd molar )

Question 24

Intraoral fulcrum with an altered point of contact between middle and ring fingers in grasp

NOT same as split fulcrum where ring finger does not touch middle finger

Point of contact is lower against middle finger

Answer 24

Modified Intraoral Fulcrum

Question 25

Intraoral finger rest in which the finger rest is established on opposite side of arch from the treatment area Ex: clinician fulcrums on left posteriors while working on right posterior teeth

Answer 25

Cross Arch

Question 26

Intraoral fulcrum established on opposite arch from tx area Ex. Fulcrum on mand teeth while working on max (Deep pockets or hard to reach area)

Answer 26

Opposite Arch

Question 27

Intraoral fulcrum in which finger of non dominant hand serves as resting point for dominant hand (Possibly mand anterior for bigger sized pt)

Answer 27

Finger on Finger

Question 28

Extra oral fulcrums are grasped farther from working end

Answer 28

Yes

Question 29

Extraoral Finger of non dominant hand used to concentrate lateral pressure against shank of instrument -Right handed use left index finger to apply pressure -Lateral pressure pushed working end forward against the distal/mesial surface

Answer 29

Finger Assist

Question 30

Extraoral fulcrum “palm out” Vertical and oblique strokes This is used to assist in

Answer 30

Maxillary right posterior distal and mesial surfaces

Question 31

Extraoral fulcrum Vertical strokes Can be used for

Answer 31

Max anteriors

Question 32

Cross arch fulcrum Working end toe up Short horizontal strokes

Answer 32

Max mesial root concavities

Question 33

Answer 33

Finger assist Palm down
