Answer 5

-Pocket depth >5.5 mm

Question 6

What kind of probe do you use on an implant?

Answer 6

Plastic! Never metal.

Question 7

When charting recession, the distance from CEJ to gingival margin, if its apical its recorded how? If gingival margins is above CEJ, how is it recorded?

Answer 7

Apical=With a + positive number.

Coronal=Negative - number

Question 8

What are the millers mobility index? I, II, III?

Answer 8

I: 1st sign of movement greater than normal
II: Movement of crown up to 1mm.
III: Movement more than 1 mm, or vertical movement.

Answer 9

I: No loss of bone, but pocket reaches furcation.
II: Loss of bone in furcation, but not all the way
III: Loss of bone all the way through
IV: Clearly visible furcation all the way through because of gum recession.

Answer 13

Movement of tooth when in function.

Question 14

What is angular bone loss?

Answer 14

Bone loss on one root surface is greater than on the other.

Question 15

Which type of bone loss (horizontal/vertical) can be regenerated?

Answer 15

Vertical.

Question 16

What is slight, moderate, and severe radiographic bone loss levels?

Answer 16

Slight= up to 15% of root length loss
Moderate= 16-30% of root length loss
Severe= Greater than 30% of root length loss

Question 17

What is the treatment protocol?

Answer 17

1. OHI and discussion of treatment plan
2. Scaling, root planing, management of local factors.
3. Re-evaluation and OHI re-inforcement
4. Probing depth resolved-maintenance
5. Probing depth not resolved…Surgery
