Grant number: 454618 | Funding period: 2007 - 2009



Chronic periodontitis (gum disease) is a chronic inflammatory disease of the supporting tissues of the teeth associated with bacteria that results in the destruction of tooth support and can ultimately lead to tooth loss. The disease is a major public health problem with a large economic burden and has been associated with an increased risk of cardiovascular disease. The bacterium Porphyromonas gingivalis is recognized as the major causative pathogen in the development of chronic periodontitis. This bacterium is part of subgingival dental plaque, a biofilm attached to the surface of the tooth below the gum line, and releases a range of proteins and cytotoxic agents that cause damage to the t..
