Using the periodontal six/four point chart, if more than 30% of sites are involved then a diagnosis of generalised disease is given. If less than 30% of sites are involved, then the type of periodontitis is localized. To complete the diagnosis, the extent of the disease must be assessed.
Consequently, a new classification was developed at the International Workshop for a Classification of Periodontal Diseases and Conditions in 1999. This covered in much more detail the full range of periodontal diseases. "Adult periodontitis" was reclassified "chronic periodontitis" and "early-onset periodontitis" to "aggressive periodontitis".

Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. [5] In its early stage, called gingivitis , the gums become swollen and red and may bleed. [ 5 ]
[1] [2] At least 16 systemic diseases have been linked to periodontitis. These systemic diseases are associated with periodontal disease because they generally contribute to either a decreased host resistance to infections or dysfunction in the connective tissue of the gums, increasing patient susceptibility to inflammation-induced destruction.

Chronic periodontitis is one of the seven categories of periodontitis as defined by the American Academy of Periodontology 1999 classification system. Chronic periodontitis is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues that is caused by the accumulation of profuse amounts of dental plaque.
According to the 1999 International Workshop for the Classification of Periodontal Diseases, aggressive periodontitis was defined according to 3 primary features, [17] in contrast to chronic periodontitis. [18] These features are common for both localized and generalized form of disease. [19] [20]
Periodontal charting refers to a chart utilized by a dental care professional (periodontist, dentist, registered dental hygienist) to write and record gingival [1] and overall oral conditions relating to oral and periodontal health or disease.
