One of the first major and comprehensive classifications of periodontitis emerged from the World Workshop in 1989.³⁷ On this date, the World Workshop in Clinical Periodontics gathered scientists and researchers to develop a classification for periodontal diseases. There were essentially five different classifications, which are listed in Box 2-3.³⁷

Under the 1989 classification system, age of onset and distribution of lesions were taken into consideration for classifying adult periodontitis and early onset periodontitis as well as the subforms of early-onset periodontitis that included prepubertal periodontitis (generalized/localized), juvenile periodontitis (generalized/ localized), and rapidly progressive periodontitis.³⁷
