2017: disease stage classiications

Answer 7

1. stage I: 1-2 mm attachment and…
2. stage II: 3-4 mm attachment loss and…
3. stage III: 5 or more attachment loss and…
4. stage IV: 5 or more attachment loss and..

Question 8

2017: disease grade

Answer 8

A, B, C

Question 9

what is the instrumentation aspect of initial periodontal therapy

Answer 9

scaling and root planing

Question 10

what is the process by which plaque and calculus is removed from all tooth surfaces coronal to the junctional epithelium

Answer 10

scaling

Question 11

what is the process by which residual plaque, calculus and portions of cementum or dentin are removed to produce a smooth, hard, clean root surface

Answer 11

root planing

Question 12

does calculus contribute to gingival inflammation

Answer 12

yes

Question 13

what does scaling remove

Answer 13

plaque and calculus from enamel surfaces

Question 14

what does root planing remove

Answer 14

inflammation-provoking plaque and calculus near cementum

Question 15

forms of subgingival calculus

Answer 15

nodular and veener

Question 16

what are small to large “bumps” that are usually easy to detect

Answer 16

nodular sub-gingival calculus

Question 17

what is a flat sheet of calculus that is usually difficult of impossible to detect

Answer 17

veneer sub-gingival calculus

Question 18

where does calculus initially form

Answer 18

CEJ

Question 19

where is calculus mostly missed? why?

Answer 19

at the CEJ

when using the up-stroke with the explorer at the CEJ, you may not be able to determine if what you are feeling is just the CEJ or calculus along the CEJ

Question 20

are scaling and root planing separate procedures

Answer 20

NOOOO!

scaling without root planing will often be inadequate to remove all the factors responsible for gingival inflammation

Question 21

is the patients ability to remove plaque effectively an important factor in ultimate success?

Answer 21

YES!

no matter how thorough you are with instrumentation, poor plaque control by pt will inevitably result in recurrent marginal inflammation

Question 22

what can be used for scaling

Answer 22

scalers, curettes, and cavitron

Question 23

type of curettes

Answer 23

1. universal: B1-2 and McCall 17-18
2. Gracey: G1-2, 11-12, 3-14

Question 24

angulation of universal curette vs. gracey

Answer 24

universal: 90 degrees
gracey: 70 degrees

Question 25

the blade of a _____ has a round toe and back, and two cutting edges for scaling, making it an efficient design for scaline the entire mouth

Answer 25

universal curettes

Question 26

____ are area specific to allow for deep scaling, root planing and periodontal debridement

Answer 26

gracey curettes

Question 27

how many cutting edge on gracey

Answer 27

one

Question 28

which gracey: - anterior teeth - scaling deeper pockts - root planing strkoes

Answer 28

gracey 1-2

Question 29

which gracey: - mesial 2/3 surface of posterior teeth - scaling deeper pockets - root planing strokes

Answer 29

gracey 11-12

Question 30

which gracey: - distal 1/3 surface of posterior teeth - scaling deeper pockets - root planing strokes

Answer 30

gracey 13-14

Question 31

ideal angulation for insertion

Answer 31

0-40 degrees

Question 32

angulation for calculus removal/ working angle

Answer 32

45-90 degrees

Question 33

IDEAL angulation for calculus removal

Answer 33

60-90 degrees

Question 34

what angle is beyond a good working angle, and removes soft tissue from inner pocket

Answer 34

greater than 90 degrees

Question 35

on that picture with the angulation of the gracey, what does each letter represent from left to right

Answer 35

A) 0-45 degrees - INSERTION B) 45-90 degrees - WORKING ANGLE C) 0-40 degrees - INSERTION D) >90 degrees NOT GOOD

Question 36

do you use just one type of stroke to remove all deposits? why or why not?

Answer 36

NO! varying the strokes allow deposits not to be missed

Question 37

does the universal curette have both edges of the blade as cutting edges?

Answer 37

YES. just like scaler

Question 38

methods for using universal curette

Answer 38
