Question 1

What 3 groups can systemic diseases be classified into?

Answer 1

1. systemic disorders that have a major impact on the loss of periodontal tissues by influencing periodontal inflammation
2. other systemic disorders that influence the pathogenesis of periodontal diseases

there is scope to modify/add to this classification as more research evidence is produced
