Aggressive periodontitis, which may be generalized or localized, is characterized by severe and protracted gingival infections, leading to tooth loss. Amounts of microbial deposits are generally inconsistent with the severity of periodontal tissue destruction and the progression of attachment and bone loss may be self arresting (American Academy of Periodontology, 2000). The term 'aggressive periodontitis' replaced the terms 'early-onset,' 'prepubertal,' or 'juvenile periodontitis' at a 1999 International workshop for a classification of periodontal disease and conditions, where it was decided that the classification terminology should not be age dependent or require knowledge of rates of progression (Armitage, 1999). Genetic Heterogeneity of Aggressive Periodontitis Aggressive periodontitis-2 (608526) has been mapped to chromosome 1q25. [from OMIM]
