17
Q

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

A

veneer sub-gingival calculus

18
Q

where does calculus initially form

A

CEJ

19
Q

where is calculus mostly missed? why?

A

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

20
Q

are scaling and root planing separate procedures

A

NOOOO!

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

21
Q

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

A

YES!

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

22
Q

what can be used for scaling

A

scalers, curettes, and cavitron

23
Q

type of curettes

A
  1. universal: B1-2 and McCall 17-18
  2. Gracey: G1-2, 11-12, 3-14
24
Q

angulation of universal curette vs. gracey

A

universal: 90 degrees
gracey: 70 degrees

25
Q

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

A

universal curettes

26
Q

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

A

gracey curettes

27
Q

how many cutting edge on gracey

A

one

28
Q

which gracey:

  • anterior teeth
  • scaling deeper pockts
  • root planing strkoes
A

gracey 1-2

29
Q

which gracey:

  • mesial 2/3 surface of posterior teeth
  • scaling deeper pockets
  • root planing strokes
A

gracey 11-12

30
Q

which gracey:

  • distal 1/3 surface of posterior teeth
  • scaling deeper pockets
  • root planing strokes
A

gracey 13-14

31
Q

ideal angulation for insertion

A

0-40 degrees

32
Q

angulation for calculus removal/ working angle

A

45-90 degrees

33
Q

IDEAL angulation for calculus removal

A

60-90 degrees

34
Q

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

A

greater than 90 degrees

35
Q

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

A

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

36
Q

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

A

NO! varying the strokes allow deposits not to be missed

37
Q

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

A

YES. just like scaler

38
Q

methods for using universal curette

A
  1. start on distal aspect of tooth then redirect to mesial line angle

OR

  1. begin at midline then work towards distal on all teeth, then start again at midline and work on all mesial surfaces
39
Q

what instrument:

  • one end used on facial surfaces of right side and lingual surfaces of left side
  • other end used on lingual surfaces of right side and facial surfaces of left side
A

11-12 explorer OR universal curette

40
Q

can curettes be used both supra and sub gingivally

A

YES
