Q

Clinical attachment level (CAL)

A

is the estimated position of the structures that support the tooth as measured with a periodontal probe.
The clinical attachment level provides an estimate of a tooth’s stability and the loss of bone support.

23
Q

wrist rocking motion

A

hand wrist arm working together as a unit to produce a rotating motion used to move the working end of an instrument
less fatigue
motion similiar to action of turning a door knob

24
Q

digital activation

A

moving the instrument by flexing the thumb index and middle fingers
moves the instrument by making push-pull movements with fingers

will use it for sometimes for power scalers and
right upper molars

25
Q

rolling the instrument

A

roll between the thumb and the index finger

26
Q

drive finger

A

leading finger

index finger or thumb. determines the direction in which it rolls

27
Q

pivoting

A

slight swinging motion of the hand and arm carried out by balancing on the fulcrum finger
pivot is a tiny movement used to reposition the hand
the fulcrum finger acts as a pivot

28
Q

adaptation

A

positioning the first 1 to 2 mm of the working ends lateral surface in contact with the tooth

positiong of the toe third or tip third of the working end against the tooth surface ** AT
ALL TIMES

29
Q

a probing depth deeper than 3 mm indicates a

A

periodontal pocket

30
Q

what is the junctional epithelium

A

the tissue that forms the base of the sulcus by attaching to the enamel of the crown near the CEJ
distance from the gingival margin to the coronal most poart of the junctional epitheliem (BASE OF THE SULCUS)

31
Q

probing depth

A

distance in mm from the gingival margin to the base of the sulcus or periodontal pocket- measured with a probe

32
Q

in healthy tissue

A

1-3 mm

the probe tip touches the tooth near the CEJ

33
Q

in a pocket- greater than 3 mm

A

the prob tip touches the ROOT somewhere below the CEJ

34
Q

the probe tip is

A

1-2 mm of the side of the probe

35
Q

you move in _____ incriments

A

1 mm

36
Q

stroke pressure should be

A

10 and 20 g

37
Q

what technique is used to probe the mesial and distal surfaces?

A

two step

38
Q

six zones per tooth

A
  1. distofacial
  2. facial
  3. mesiofacial
  4. disolingual
  5. lingual
  6. mesiolingual
39
Q

gingival pocket is formed due to

A
  1. detachment of the coronal portion of the JE from the tooth and
  2. increased tissue size due to swelling of the tissue
40
Q

periodontal pocket is formed due to

A
  1. apical migration of the JE

2. destruction of the periodontal ligament fibers and alveolar bone

41
Q

apical migration

A

movement of the cells of the JE from their normal position - coronal to the CEJ- to a position apical to the CEJ
in periodontitis, the junctional epithelial cells attach to the cementum of the tooth root.

42
Q

the free gingiva meets the tooth at the

A

gingival margin

43
Q

periodontal attachment system

A

is a group of structures that work together to attach the teeth to the maxilla and mandible

44
Q

to remain in the oral cavity a tooth must be attached by

A
  1. JE
  2. Fibers in gingiva
  3. periodontal ligament fibers
  4. alveolar bone
45
Q

loss of attachment occurs during

A 
periodontitis
characterized by
1. relocation of the JE
2. destruction of gingival fibers
3. destruction of periodontal ligament
4. loss of alveolar bone support
46
Q

attachment in health

A

junctional epithelium attaches to enamel at base of sulcus
fibers brace the tissue against the crown
many fibers attach root to bone of socket
most of the root is surrounded by bone; the tooth is firmly held in its socked

47
Q

attachmeht in disease

A

JE attaches to cementum at base of periodontal pocket
fiber destruction, tissue lacks firmness
fewer fibers remain to hold tooth in socket
part of the root is surrounded by bone the tooth may be movable in its socket.

48
Q

loss of bone and recession of the gingival margin

A

only the gingival margin differs!

49
Q

in periodontitits there is damage to the

A

gingival connective tissue, periodontal ligament, and alveolar bone

50
Q

comprehensive periodontal assessment is

A

fact gathering process designed to provide a complete picture of a patients periodontal health status.

51
Q

recession is

A

measurment from the free gingival margin to the cej

clinical indicator of loss of attachment

52
Q

intra oral lesions are recorded in two measurments

A

anterior-posterior measurement
superior inferior measurement

for raised lesions- record height
sunken lesions record the depth

53
Q

ORAL LESIONS should be documented

A
  1. date. 2 size 3 location 4 color 5 character of the lesions, 6. any other info provided by the patient.
54
Q 
classification of mobility
class 1
A

slight mobility, up to 1 mm of horizontal displacement in a facial lingual direction

55
Q 
classification of mobility
class 2
A

greater than 1 mm but less than 2 mm of horizontal displacement in a facial lingual direction

56
Q 
classification of mobility
class 3
A

greater than 2 mm of horizontal displacement in a facial lingual direction or vertical mobility
