true

Question 13

gingival pocket

Answer 13

deepining of gingivial sulcus cause by detachment of coronal portion of JE and swelling tissue

*SWELLING
pockets are deeper b.c they are swollen. no loss of bone

Question 14

periodontal pocket

Answer 14

forms apical migration of the JE and destruction of periodontal fibers and bone
**LOSS OF BONE
more recession

Question 15

A probing depth reading ALONE is NOT enough information to tell you if a tooth has normal bone support or bone loss!
Remember, the position of the gingival margin can change with swelling, overgrowth, and recession.

Answer 15

IMPORTANT

Question 16

Probing depth readings accurately indicate the level of the bone only IF the gingival margin is in its normal position, slightly above the CEJ.

The clinical attachment level is

Answer 19

is calculated to estimate the level of the periodontal attachment system on a tooth.

Question 20

furcation

Answer 20

is the place on a multirooted tooth where the root trunk divides into separate roots.

Question 21

Furcation involvement

Answer 21

is a loss of alveolar bone and periodontal ligament fibers in the space between the roots of a multirooted tooth.

Question 22

mylenation

Answer 22

with practice of muscle memory, movements become smoother

process of forming myelin sheath around the nerve to allow nerve impulses to move mroe quickly

Question 23

wrist rocking motion

Answer 23

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

Question 24

digital activation

Answer 24

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

Question 25

rolling the instrument

Answer 25

roll between the thumb and the index finger

Question 26

drive finger

Answer 26

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

Question 27

pivoting

Answer 27

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

Question 28

adaptation

Answer 28

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

Question 29

a probing depth deeper than 3 mm indicates a

Answer 29

periodontal pocket

Question 30

what is the junctional epithelium

Answer 30

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)

Question 31

probing depth

Answer 31

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

Question 32

in healthy tissue

Answer 32

1-3 mm | the probe tip touches the tooth near the CEJ

Question 33

in a pocket- greater than 3 mm

Answer 33

the prob tip touches the ROOT somewhere below the CEJ

Question 34

the probe tip is

Answer 34

1-2 mm of the side of the probe

Question 35

you move in _____ incriments

Answer 35

1 mm

Question 36

stroke pressure should be

Answer 36

10 and 20 g

Question 37

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

Answer 37

two step

Question 38

six zones per tooth

Answer 38

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

Question 39

gingival pocket is formed due to

Answer 39

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

apical migration

Answer 41

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.

Question 46

attachment in health

Answer 46

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
