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 cavity. Viral roles in the progression of periodontal disease as of 2017 remains poorly explored. [1]
Necrotizing ulcerative periodontitis (NUP) is where the infection leads to attachment loss, and involves only the gingiva, periodontal ligament and alveolar ligament. [9] [10] [11] Progression of the disease into tissue beyond the mucogingival junction characterizes necrotizing stomatitis (cancrum oris).
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.
At the time the system was designed, the initiation of periodontal disease was thought to develop from a continuum from an inflammation-free state to gingivitis, to calculus deposition and pocket formation and then to progressive disease. Treatment concepts were based on the concept of pocket depths being the most critical criterion for ...
The rate at which coronavirus tests are coming back with positive results continues to climb across California. For the week ending July 1, 10.6% of coronavirus tests statewide came back positive ...
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.
Periapical periodontitis; Other names: Apical periodontitis, periradicular periodontitis: Periapical dental radiograph showing chronic periapical periodontitis on the root of the left maxillary second premolar. Note large restoration present in the tooth, which will have undergone pulpal necrosis at some point before the development of this lesion.
As gingivitis progresses further and is not treated, it may progress into periodontitis. Periodontal disease is when the gums surrounding the teeth become swollen causing surrounding plaque to build up. If left untreated can cause the teeth to become loose due to weak gums. Periodontal disease can compromise factors such as: [4] Gingiva
