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 .
Plaque may be soft and uncalcified, hard and calcified, or both; for plaques that are on teeth the calcium comes from saliva; for plaques below the gumline, it comes from blood via oozing of inflamed gums. [65] The damage to teeth and gums comes from the immune system as it attempts to destroy the microbes that are disrupting the normal ...
It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis. Other causes can include occlusal trauma due to 'high spots' after restoration work, extrusion from the tooth of root filling material, or bacterial ...
Early periodontitis: When left untreated, gingivitis can result in inflammation moving deeper into the gum tissues, causing pockets between the gums and teeth. Food, plaque and bacteria get ...
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.
Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
The main features are painful, bleeding gums, and ulceration of interdental papillae (the sections of gum between adjacent teeth). This disease, along with necrotizing periodontitis (NP) and necrotizing stomatitis, is classified as a necrotizing periodontal disease , one of the three general types of gum disease caused by inflammation of the ...
The signs and symptoms of gingivitis can be reversed through improved oral hygiene measures and increased plaque disruption. If left untreated, gingivitis has the potential to progress to periodontitis and other related diseases that are more detrimental to periodontal and general health. [10]
