Prognosis of Periodontitis

Question 1

How do we measure the outcome to treatment?

Answer 1

PPD reduction = periodontal pocket depth
CAL = clinical attachment level gain
BOP reduction
Reduction in furcation
Reduction in mobility
Improvement in patient symptoms
Reduction in local/systemic inflammation

Long term stability:
No tooth loss
Good masticatory function
No patient symptoms
Reduced local/systemic inflammation

Question 2

What are some patient specific and site specific prognostic factors for a patient getting periodontitis?

Answer 2

Patient:
Age
Gender
Plaque levels
Smoking levels
Genetic levels
Socio-economic factors
BMI
Stress
Systemic disease e.g. diabetes

SITE:
Pocket depth
Vertical bone loss
Residual bone support
Furcations
BOP
Mobility

Question 3

What are some indicators that a tooth has a hopeless prognosis?

Answer 3

Possibly includes:
Mobility > 2
Furcation grade 3
Bone loss >70%
Pockets over 10mm
