Questions and Answers

What is another name for Aggressive Periodontitis?

Early onset periodontitis

What is the primary difference between localized and generalized aggressive periodontitis?

  • The distribution of periodontal destruction in the mouth (correct)
  • The rate of bone loss
  • The presence of subgingival calculus
  • The age of onset
