1
Q

Q

What needs to be checked during a periodontal assessment? (5)

6
Q

How can pseudopockets arise?

A
  • Gingival swelling

  • Anatomical factors (ie partially erupted teeth)
7
Q

What are pseudopocktes?

A

False pockets where PPD is falsely greater than 3mm and there is no attachment loss

8
Q

When should a Basic periodontal examination (BPE) be carried out?

A

Should be used as a part of all routine dental examinations in adults and children aged above seven

9
Q

Describe the BPE method (4)

A
  • Dentition is divided into sextants
  • Examination is carried out with a WHO/BPE probe
  • Probe gently inserted into the gingival crevice and ‘walked around’
  • For each sextant only the highest score is recorded
10
Q

What does a ‘X’ on a BPE examination indicate?

A

Signifies a sextant that is edentulous or has only 1 functioning tooth

11
Q

What does a ‘*’ on a BPE examination indicate?

A

Signifies furcation involvement and is used as an adjective score

12
Q

What would you see for a BPE score of 0;

Probing depth?
Black band visibility?
Bleeding?
Overhangs/Calculus?

A
  • <3.5mm
  • Completely visible
  • No
  • No
13
Q

What would you see for a BPE score of 1;

Probing depth?
Black band visibility?
Bleeding?
Overhangs/Calculus?

A
  • <3.5mm
  • Completely visible
  • Yes
  • No
14
Q

What would you see for a BPE score of 2;

Probing depth?
Black band visibility?
Bleeding?
Overhangs/Calculus?

A
  • <3.5mm
  • Completely visible
  • Yes or No
  • Yes
15
Q

What would you see for a BPE score of 3;

Probing depth?
Black band visibility?
Bleeding?
Overhangs/Calculus?

A
  • 3.5mm-5.5mm
  • Partially visible
  • Yes or No
  • Yes or No
16
Q

What would you see for a BPE score of 4;

Probing depth?
Black band visibility?
Bleeding?
Overhangs/Calculus?

A
  • > 5.5mm
  • Entirely within pocket
  • Yes or No
  • Yes or No
17
Q

What treatment is needed for a BPE score of 0

A

No treatment

18
Q

What treatment is needed for a BPE score of 1

A

Oral hygiene advice

19
Q

What treatment is needed for a BPE score of 2 (3)

A
  • Scaling
  • Oral hygiene advice
  • Elimante plaque retentive restorative margins
20
Q

What treatment is needed for a BPE score of 3 (5)

A
  • Scaling
  • Root surface debridement
  • Oral hygiene advice
  • Elimante plaque retentive restorative margins
  • Full 6 point probing chart needed of the sextant
21
Q

What treatment is needed for a BPE score of 4 (5)

A
  • Scaling
  • Root surface debridement
  • Oral hygiene advice
  • Elimante plaque retentive restorative margins
  • Full 6 point probing chart needed of the sextant

Much more complex treatment

22
Q

What are the 6 reference teeth used in paediatric BPE?

A

UR1 UR1 UL6

LR1 LR1 LL6

23
Q

What codes do you use for paediatric BPE?

When should you use full range of codes?

A
  • Only use 0,1,2

- 12+

24
Q

What are 2 advantages of BPE?

A
  • Simple and rapid screening to identify periodontal risk

- Good indication of treatment required

25
Q

What are some disadvantages of BPE? (5)

A
  • Not designed to monitor patients
  • No distinction between true and false pockets
  • Lack of detail within sextant
  • No detail about recession
  • No detail about furcation involvement
26
Q

When and why is a six point pocket chart (6PPC) used?

A
  • When full periodontal assessment is required
  • When we record BPE score 3 and 4
  • Gives 6 measurements for each tooth (more detailed)
27
Q

What probes are used for 6PPCs?

Williams or UNC15

How are clinical crown to root (C:R) ratios determined?

A

Amount of root remaining in bone compass with the amount of tooth above the bone level

Q

What is horizontal bone loss?

A

If the level of the bone is essential equal interdentally, it is called horizontal bone loss

(measured as % bone lost)

32
