Perio Questions

Question 1

What are some problems with BPE?

Answer 1

Only gives score for deepest pocket in sextant so you can’t tell if periodontitis is generalised or local

Question 2

What is a BPE?

Answer 2

Screening tool used to identify disease status

Aids treatment planning

Question 3

When is a BPE carried out?

Answer 3

Done for ALL patients on first visit

Question 4

What is a 6PPC? And what does it allow you to do?

Answer 4

Measurement of health of gingiva and bone and measure depth of gingival sulcus.

• Aids definitive diagnosis
• Assess scale of periodontal disease
• Plan treatment
• Gives baseline for assessing success of treatment outcome.

Question 5

When is a 6PPC carried out?

Answer 5

Full after score 4, partial after score 3 only in that sextant.

Question 6

How do you record a 6PPC?

Answer 6

use a PCP-12 probe

• patient name, CHI, date
• Record missing teeth
• Measure gingival margin relative to ACJ
• Measure pocket depth
• Measure bleeding
• Measure tooth mobility
• Measure furcation involvement

Question 7

What are some problems with a 6PPC?

Answer 7

Inaccurate pocket depths/ variable between clinicians
Patient sensitivity
Length of time

Question 8

Why do you use water with ultrasonic?

Answer 8

High vibrations can cause friction and therefore damage the pulp via heat transfer but the water acts as a coolant to avoid this is you also keep the tip moving constantly

Question 9

What is PCP-12 probe?

Answer 9

Used for 6PPC
12 mm in length
black marks at 3-6mm and 9-12mm

Question 10

What is WHO probe?

Answer 10

Used for BPE
0.5mm black round ball on end
Black marks at 3.5-5.5mm and 8.5-11.5mm.

Question 11

What are the mobility gradings?

Answer 11

0 - none
1 - mobility less than 1mm bucco-lingually
2 - mobility between 1-2mm bucco-lingually
3 - mobility more than 2mm in a horizontal and vertical direction

Question 12

What are the grades of furcation involvement?

Answer 12

1 - probe goes <3mm into furcation
2 - probe goes >3mm into furcation
3 - through and through

Question 13

What is a modified plaque and bleeding scores purpose?

Answer 13

Used to determine patient engagement

Question 14

When is a MPBS carried out?

Answer 14

NOT first appt.

Every appt. following this

Question 15

What are the ramfjord’s teeth?

Answer 15

The teeth used in MBPS. Gives overview of mouth.

16, 21, 24, 36, 41, 44

Question 16

What are the plaque scores in MPBS?

Answer 16

Visualisation of plaque on each surface of tooth - buccal, lingual and interproximal.

0 - no plaque
1 - no visible plaque but plaque present with probe detection
2 - visible plaque

Question 17

What is the definition of an ‘engaging patient’ in MPBS?

Answer 17

Patients should aim for less than 30% plaque score and less than 35% bleeding score
or
50% improvement in both in between appointments.

Question 18

What are bleeding scores in MPBS?

Answer 18

Measure of marginal bleeding rather than BOP from base of pocket.

4 surfaces - mesial, distal, buccal, lingual

1 = bleeding
0 = no bleeding

Question 19

What does marginal bleeding vs BOP at base of pockets show?

Answer 19

Marginal bleeding - reflects how well patient is able to carry out effective plaque control daily.

BOP at base of pockets - indicates disease activity and periodontal breakdown.
