Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses. Viruses that specifically infect bacteria—bacteriophages—are most common in the oral ...
Periodontal pathology, also termed gum diseases or periodontal diseases, are diseases involving the periodontium (the tooth supporting structures, i.e. the gums). The periodontium is composed of alveolar bone , periodontal ligament , cementum and gingiva .
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] It is considered the main cause of tooth loss for adults worldwide.
A dynamic equilibrium exists between dental plaque bacteria and the innate host defense system. [7] Of particular interest is the role of oral microorganisms in the two major dental diseases: dental caries and periodontal disease. [7]
Periodontitis is a form of gum disease that affects approximately 90% of adults globally. It is associated with other chronic inflammatory conditions, and can progress to the point that it can ...
Gingivitis is a non-destructive disease that causes inflammation of the gums; [1] ulitis is an alternative term. [2] The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that are attached to tooth surfaces, termed plaque-induced gingivitis.
Often, this leads to opportunistic pathogens which may cause dental caries and periodontal disease. Pathogenic bacteria that have the potential to cause dental caries flourish in acidic environments; those that have the potential to cause periodontal disease flourish in a slightly alkaline environment.

Necrotizing periodontal diseases are a type of inflammatory periodontal (gum) disease caused by bacteria (notably fusobacteria and spirochaete species). The diseases appear to represent different severities or stages of the same disease process, although this is not completely certain. These diseases usually have a sudden onset.
