to study etiology, pathogenesis and treatment of perio disease
Provide clinician with rationale for treatment and provision of care

Aggressive and chronic

Question 4

6 common features of aggressive periodontitis

Answer 4

1. apart from presence of periodontitis, patient are have relatively good oral health

4. familial aggregation
5. Usually associated with actinobacillus actinomycetemcomitans (a.a)
6. usually associated with hyperresponsive macrophage phenotype

Question 5

3 common features of localised aggresive perio

Answer 5

1. circumpubertal onset

Answer 6

1. <30 yrs old
