Supportive Periodontal Therapy and Recall Strategies

Question 1

how to determine loss of periodontal support

Answer 1

mm of bone loss (take worst site affected) x 100 / patient’s age

Question 2

parameters for BOP (low, moderate, high)

Answer 2

low: <10%
moderate: 10-25%
high: >25%

Question 3

how do you determine recall of 2x/year vs. 4x/year for NO ACTIVE or hx of periodontitis?

Answer 3

4x / year: greater than or equal to 3 / 6 “high” markings

2x/ year: all others

Question 4

what are the measured parameters for risk assessment? (6)

Answer 4

1. BOP
2. number of pockets
3. loss of periodontal support (low is greater than or equal to 0.5, high is greater than 1)
4. diabetes
5. cigarette smoking
6. number of missing teeth (excludes 3rd molars)

Question 5

How do you determine recall for active or hx of periodontitis?

Answer 5

2x/year: no more than 1 moderate, all others low

3x/year: no more than 1 high, two or more moderate

4x/year: 2 or more high

Question 6

What is the scheduling of radiographic examinations for poor controlled periodontal disease vs. controlled?

Answer 6

poor controlled: PA and/or vertical BWs of problem areas every 1-2 years, FMX every 3-5 years

controlled disease: BW every 2-3 years, FMX every 5 years

Question 7

What are 4 symptoms of recurrence of disease?

Answer 7

1. increased mobility: inflammation? occlusal trauma?
2. recession: periodontal disease? mechanical trauma?
3. increased pocket depth: poor OH? medication? tooth fracture?
4. alveolar bone loss: periodontal disease? tooth fracture?

Question 8

At present, no accurate method of predicting disease activity exists, and clinicans rely on the information provided by clinical findings. What are 7 important findings?

Answer 8

• probing depth
• attachment level
• BOP
• mobility
• suppuration
• alveolar bone loss
