Q

What is periodontitis?

A

An inflammatory process that affects the periodontal supporting structures ( gingiva, periodontal ligament, cementum and alveolar bone)
Causes by host/ parasite interactions leads to loss of connective tissue (PDL) and can also be resorption of alveolar bone
Forms pockets and teeth can become mobile

Q

What is looked out for in a BPE?

A

Screening involves assessing bleeding, presence of plaque or calculus and the depth of periodontal pockets which may be present

Q

How are BEP scores recorded for adults?

A
  1. Only done for anterior 3 and posterior 4-7 (8 are never included due to not always being present)
  2. Split the mouth into sextants (6ths and must have at least 2 teeth) and all teeth are examined
  3. Probe is gently walked around gingival sulcus/pocket (20-25g of pressure)
  4. Highest score is taken at each sextant

Q

How instrument is used for a BPE screening? And what makes it special?

A

WHO probe
- has a rounded ball end with a 0.5 diameter
- a black band which around 3.5-5.5mm and one at 8.5-11.5mm to measure pockets
Use around 20-25g of pressure when probing

Q

What are the uses of a BPE check?

A
  • Allows for quick assessment of periodontal disease
  • Allows clinician to differentiate simple and complex cases

On at risk patient should be done once a year

16
Q

What is a DPC?

A

Detailed periodontal charting
A 6 point check is done, placing a probe on the long axis of the tooth going straight down recording scores at each site
1. Mesio-buccal
2. Buccal
3. Disto buccal
4. Mesio lingual
5. Lingual
6. Distolingual

17
Q

What is used to do a DPE?

A
  1. A UNC 15 - has marking at 1mm increments for 15mm
  2. Can also use a:
    Williams probe - curved so easier for posterior teeth ( 1mm increments for 10mm)
18
Q

What is Furcation involvement?

A

Only applies to multi-rooted teeth
- Mandibular molar have 2 roots so 2 Furcation entrances ( buccal and lingual)
- Maxillary molars have 3 roots so 3 Furcation entrances ( buccal mesial and distal

19
Q

How is Furcation checked? And why?

A

Nabers Furcation probe
Is curved so can check roots and also have coloured bands
1. Between 3mm-6mm
2. Between 9mm-12mm

20
Q

How is Furcation involvement graded?

A

Hamp’s classification

21
Q

What is a grade 1 on the Hamp’s classification?

A
  • Initial Furcation and opening can be felt on probing
  • Involvement < 1/3 of tooth
22
Q

What is a grade 2 on the Hamp’s classification?

A
  • Partial Furcation involvement
  • Loss of support exceeds 1/3
    >1/3
23
Q

What is a grade 3 on the Hamp’s classification?

A
  • Involvement all the way through, probe passes all the way through
    100%
24
Q

What is recession?

A

Pocket depth is normally from the CEJ to the base of the pocket
- with recession this pocket depth increases due to an increased pocket size therefore it’s adding on the probing depth

25
Q

What is tooth mobility? What causes it?

A

Cause by alveolar bone loss and tooth may feel lose
1. Horizontal mobility - measured with genital pressure in buccal-lingual surfaces using rigid instruments
2. Verticals mobility - measured by applied genital pressure to crown with ridge instrument to see movement

26
Q

How is tooth mobility graded?

A

Millers classification

27
Q

What is a 0 on the millers classification?

A

Very little tooth movement 0.1-0.2mm (within normal rage )

28
Q

What is a 1on the millers classification?

A

Increased mobility of crown on the horizontal direction up to 1mm

29
Q

What is a 2 on the millers classification?

A

Visually increased mobility of crowns in horizontal direction exceeding 1mm

30
Q

What is a 3 on the millers classification?

A

Sever mobility of the crown in both horizontal and vertical direction impinging on other teeth function

31
Q

What are risk factors for Perio disease?

A
  1. Tobacco - increases risk of periodontal disease and reduces benefits if treatment and increases chance of losing teeth
  2. Diabetes - must maintain good control as they have greater risk of developing serious periodontal disease and get less benefit from perio-treatment
32
Q

What advice can be given to prevent periodontitis?

A
  1. Remove plaque using method the dental teams shows this reduces risk of periodontal disease, daily effective brushing is important for Perio health more than scaling occasionally
  2. Toothbrushing - must clean at the gum line twice a day especially at night using a manual or electric toothbrush
    Use a soft-medium brush with a small brush head
  3. Toothpaste - must contain fluoride
33
Q

How to talking to patients about quitting smoking?

A

Must be very brief so it doesn’t sound like we are judging or lecturing

  1. Ask - establish record or smoking and frequency
  2. Advice - talk about the negative impacts it has to oral health and benefits of stopping
  3. Act - offer help to stop
34
Q

What treatment will be done for a patient with BOE codes 1-2?

A

They need to have normal appointments and give then advice on how to brush a little more effectively and other oral health tips
- Next check up in a year

35
Q

What treatment will be done for a patient with BOE codes 3-4?

A

They need a detailed periodontal charting (DPC)

36
Q

What are the differences in treatment between a code 3 and code 4 BPE patient?

A

Code 3 - Has a DPC (6 point check) only in the affected sextant

Code 4 - Has a DPC (6 point check( in the whole mouth all sextants

Both patient receive initial treatment, removal of plaque and scaling also told about mitigating risk factors e.g. smoking or diabetes
