45
How can you assess patient engagement with periodontal services
Modified plaque and bleeding scores
46
What surfaces are used for modified plaque scores
Interproximal Buccal Lingual
47
What surfaces are used for modified bleeding scores
Buccal Lingual Mesial Distal
48
Modified plaque scores (3)
0 - No plaque 1 - No visible plaque but a probe reveals plaque 2 - Visible plaque
49
Modified bleeding scores
0 - No bleeding 1 - Bleeding
50
How do you calculate modified plaque score
Add up the score for each surface and divide by max possible score (36)
51
What does modified bleeding score measure
Marginal bleeding which indicates how well the patient is able to carry out effective plaque control daily
52
How should you carry out a modified bleeding score (3)
Use ramfjords teeth Run a probe around margins in continuous sweep at 45 degree angle Check for bleeding up to 30 seconds after
53
How do you calculate modified bleeding score
Score / 24 Or max possible score
54
What should you do if one or Ramfjords teeth is missing
Use a similar alternative tooth
55
When should you calculate plaque and bleeding scores
Not needed at initial session Every subsequent session
56
Goals for modified plaque and bleeding scores (3)
Plaque <30% Bleeding <35% Or more than a 50% improvement
57
What is the length of biological width
Connective tissue + junctional epithelium 2mm
58
Supportive Periodontal Care Tx (3)

Talk Instruct Practice Plan Support
60
