Basically green tea is the least processed of four different types of tea; green, oolong, black and white, all of which come for the Camellia sinensis bush. Unlike the other tea variants, green tea leaves are steamed. Processing them in this way preserves the compound epigallocatechin gallate (EGCG), which is a powerful antioxidant that gives green tea many of its health properties.
Evidence indicates that periodontal disease is an autoimmune disorder triggered by infectious organisms and an abnormal immune response to collagen. Periodontal disease is an inflammatory condition affecting both the gums and the deep structures that house the roots of the teeth.eriodontal disease can cause the teeth to loosen and decay. Individuals with periodontal disease may experience bleeding of the gums when brushing, which is often the first sign of a problem. The gums may also appear swollen and recede away from the teeth.
Some bacteria are related to gingivitis, but not plaque development. They include various streptococcal species. Evidence now suggests that periodontal disease is an autoimmune disorder, in which immune factors in the body attack the person''s own cells and tissue -- in this case, those in the gum. Bacteroides forsythus is also strongly linked to periodontal disease. 2  Other bacteria associated with periodontal disease are Treponema denticola, T. socranskii, and P. intermedia. 3  These bacteria, together with P. gingivalis, are frequently present at the same sites, and are associated with deep periodontal pockets.
