Question 1

What is the sequence of carrying out a 6PPC?

Answer 1

Buccal Q1
Buccal Q2
Palatal Q2
Palatal Q1
Buccal Q4
Buccal Q3
Lingual Q3
Lingual Q4
Record gingival margin, pocket depth, BoP, furcation and any mobility

Question 2

What information is recorded on a review pocket chart?

Answer 2

Pocket equal to or greater than 4mm (whole mouth is probed)

Plaque, calculus and BoP

Question 3

What are the advantages and disadvantages of a 6PPC?

Answer 3

Advantages - gives a full picture of periodontal attachment loss
Disadvantage - Is more time consuming

Question 4

What are the advantages and disadvantages of an abbreviated/review pocket chart?

Answer 4

Advantages - Quicker to complete than 6 PPC. Can efficiently highlight areas requiring further treatment.
Disadvantages - Does not record periodontal attachment loss, which could therefore progress unrecorded

Question 5

In ultrasonic debridement, what factors lead to root surface loss and ledges?

Answer 5

• Excessive lateral force
• Incorrect angulation/adaptation
• Incorrect insert width
• Excessive power

Question 6

Describe the mini sickle (Red)

Answer 6

• Red
• Double ended point scaler
• Two cutting edges on each blade
• Used on buccal and lingual embrasure surfaces supragingivally
• Limited in subgingival use

Question 7

Describe the hoe scaler 134-135 (yellow)

Answer 7

-Double ended instrument for gross supra and subgingival scaling mainly on buccal and lingual surfaces

Question 8

Describe the hoe scaler 156-157 (red)

Answer 8

-A double ended instrument for gross supra and subgingival scaling mainly on mesial and distal surfaces

Question 9

Describe the Columbia curette (red)

Answer 9

• Double ended universal curette with two cutting edges on each blade for subgingival scaling anywhere in the mouth but with limited access to deep pockets.
• A curved spoon shaped blade with two cutting edges, which meet to form a rounded toe

Question 10

What is the application of the Gracey curette 1-2 (Grey)

Answer 10

Subgingival scaling anterior teeth

Question 11

What is the application of the Gracey curette 7-8 (Green)

Answer 11

Subgingival scaling buccal and lingual surfaces

Question 12

What is the application of the Gracey curette 11-12 (Orange)

Answer 12

Subgingival scaling mesial surfaces of posterior teeth

Question 13

What is the application of the Gracey curette 13-14 (Blue)

Answer 13

Subgingival scaling distal surfaces of posterior teeth

Question 14

What are Ramfjords teeth and what are they used for?

Answer 14

16, 21, 24, 36, 41, 44

These six teeth are used to record plaque and bleeding index

Question 15

What surfaces of Ramfjords teeth are used in a modified plaque score?

Answer 15

• Interproximal
• Buccal
• Palatal/lingual

Question 16

What are the three possible scores in a modified plaque score?

Answer 16

2 = visible plaque without use of a probe
1 = no visible plaque but a probe skimmed over tooth surface reveals plaque
0 = no plaque

All scores are added together to give a total, which is then divided by the maximum plaque score possible (36)

Question 17

What is the purpose of staging periodontal disease and what are the four stages?

Answer 17

Staging is based on severity.
Stage 1 - Early/mild. Interproximal bone loss less than 15% or 2mm
Stage 2 - Moderate. Coronal third of root involved.
Stage 3 - Severe (potential for additional tooth loss), mid third of root involved.
Stage 4 - very severe (posential for loss of dentition) Apical third of root involved

Question 18

What is the purpose of grading periodontal disease and what are the three grades?

Answer 18

Grading indicates the progression of bone loss.
Grade A - slow - less than half patients age
Grade B - moderate half to equal to patients age
Grade C - rapid - greater than patients age

Question 19

How is the extent of periodontal disease recorded?

Answer 19

• Localised - less than 30% of teeth
• Generalised - greater than 30% of teeth
• Molar incisor pattern

Question 20

Describe type 1 recession

Answer 20

Gingival recession with no loss of interproximal attachment. Interproximal CEJ is clinically not detectable at both mesial and distal aspects of the tooth

Question 21

Describe type 2 recession

Answer 21

Gingival recession associated with interproximal LOA. The amount of LOA is less than or equal to the buccal attachment loss.

Question 22

Describe type 3 recession

Answer 22

Gingival recession associated with loss of interproximal attachment. The amount of interproximal attachment loss is greater than the buccal attachment loss.
