This introductory overview presents the schematic tables for the new classification of periodontal and periâimplant diseases and conditions and briefly highlights changes made to the 1999 classification. In 1989, a classification system was proposed that included five types of periodontitis: adult periodontitis, early onset periodontitis, periodontitis associated with systemic disease, necrotizing ulcerative periodontitis, and refractory periodontitis.2 This system was widely used among practitioners although a gingival disease component was missing and there was an overlap of disease categories.3 In addition, some criteria appeared to be unclear or inadequate.3 Given that changes were needed, in 1999, the classification system for periodontal diseases and conditions was updated. 2015;86:835-38.

Armitage G. Development of a classification system for periodontal diseases and conditions. Periodontal health and gingival diseases and conditions are outlined in Table 1.6 Parameters defined at the 2017 World Workshop specified that bleeding on probing was the primary consideration in setting thresholds for gingivitis.7.8 Further, it was noted that a patient with gingivitis can revert to a state of health; however, a patient with periodontitis must be followed for life to prevent recurrence of disease.9, The classification of periodontitis was modified to recognize three forms of periodontitis: necrotizing periodontitis, periodontitis as a manifestation of systemic disease, and a single category of periodontitis with staging and grading criteria as presented in Table 2.6 Staging is established by factors such as clinical attachment loss, bone loss, probing depth, furcation involvement, mobility, and tooth loss.
