Q

What is the code 4 pathway of treatment?

A
  • radiographic assessment
  • ## full 6PPC
17
Q

What is the types of periodontitis?

A

molar incisor pattern
localised (less than 30% of sites bone loss)
generalised (more than 30% of sites bone loss)

18
Q

What are the staging of periodontitis?

A

Stage 1 - mild - 15% bone loss at worst site
Stage 2 - coronal third of root
Stage 3 - mid third of root - Stage III
Stage 4 - Apical third of root - Stage IV

19
Q

how to grade bone loss ?

A

% of bone loss at worst site / patient age

20
Q

What are the grades of periodontitis?

A
  • Grade A - less than 0.5
  • Grade B - 0.5-1.0
  • Grade C - more than 1
21
Q

How to assess current periodontal status?

A
  • currently stable ( less than 10% bleeding , less than 4mm pockets)
  • currently in remission ( more than 10% bleeding on probing , pockets more than 4mm, no probing on bleeding at mm sites)
  • currently unstable ( bleeding on probing on sites of 4mm)
22
Q

What is involved in Step 1 periodontitis?

A
  • Explain disease , risk factors
  • OHI
  • reduce risk factors
  • Supra and subgingival PMPR of the crown
  • interdental cleaning
  • Oral health educator
    -recall in 8 weeks
  • re-evaluate and if improved move to step 2
23
Q

What is involved in Step 2 periodontal treatment?

A
  • Subgingival intrumentation
  • OHI
  • subgingival instrumentation
  • hand or powered
  • use systemic antimicrobials
  • re-evaluate in 3 months
24
Q

What is involved in step 3

A
  • if not stable after step 2
  • managing non responding sites
  • OHI
  • risk factor control
  • behavioural change
  • pockets of 4-5mm = subgingival instrumentation
  • pockets of more than 6mm = consider referral for periodontal surgery
25
Q

What is involved in step 4

A
  • if all sites are stable after step 3
  • Maintenance
    -supportive periodontal care
  • reinforce OHI
  • targeted PMPR
    recall every 3-12 months
26
Q

What is the criteria for an engaging patient?

A

-Favourable improvement in OH indicated by 50% improvement in plaque and marginal bleeding
- plaque levels <20% and bleeding levels 30%
- Patient has met the targets outlined in their personal self care plan as determined by their healthcare practitioner

27
Q

What is a non engaging patient?

A
  • inssuficient improvement in OH - indicated by more than 50% improvement in plaque and marginal bleeding
  • plaque levels more than 20% and bleeding more than 30%
  • patient states preferance to palliative care than periodontal care
