Inclusion criteria
Inclusion criteria: Aggressive Periodontitis: according to the AgP diagnostic criteria established by the international symposium on classification of periodontal diseases in 1999 (1) Aged 18 to 35 years old; (2) Rapid alveolar bone destruction and attachment loss: the probing depth of at least 6 teeth (at least 3 of them are non-first molars and incisors) in the whole mouth is greater than 5mm, and the adjacent attachment loss is greater than 3mm.
