The bacteria found in the biofilm elicit a host response resulting in localized inflammation of the tissue. [22] This is characterized by the cardinal signs of inflammation including a red, puffy appearance of the gums and bleeding due to brushing or flossing. [23] Gingivitis due to plaque can be reversible by removal of the plaque.
A dynamic equilibrium exists notably between the bacteria of dental plaque and the host's immune system, enabling the plaque to stay behind in the mouth when other biofilms are washed away. [19] In equilibrium, the bacterial biofilm produced by the fermentation of sugar in the mouth is quickly swept away by the saliva, except for dental plaque.
There is inflammation due to the bacteria released from the toxins. calculus forms and if not removed, causes this disease. [5] In most cases, the cause of gingival diseases such as gingivitis are due to poor oral hygiene. This is the most common of causes for gingival diseases. though other factors included are: Smoking; Diabetes; Female ...
While S. mutans grows in the biofilm, cells maintain a balance of metabolism that involves production and detoxification. Biofilm is an aggregate of microorganisms in which cells adhere to each other or a surface. Bacteria in the biofilm community can actually generate various toxic compounds that interfere with the growth of other competing ...
The microorganisms that form the biofilm are almost entirely bacteria (mainly streptococcus and anaerobes), with the composition varying by location in the mouth. [41] Streptococcus mutans is the most important bacterium associated with dental caries. Certain bacteria in the mouth live off the remains of foods, especially sugars and starches.
Supragingival calculus formation is most abundant on the buccal (cheek) surfaces of the maxillary (upper jaw) molars and on the lingual (tongue) surfaces of the mandibular (lower jaw) incisors. [18] These areas experience high salivary flow because of their proximity to the parotid and sublingual salivary glands .
Periodontal disease typically arises from the development of plaque biofilm, which harbors harmful bacteria such as Porphyromonas gingivalis and Treponema denticola. These bacteria infect the gum tissue surrounding the teeth, leading to inflammation and, if left untreated, progressive damage to the teeth and gum tissue. [ 9 ]
Bacterial toxins and the body's natural defenses start to break down the bone and connective tissues. The tooth may eventually become loose and have to be removed. Scarlet fever is caused by a particular streptococci species, Streptococci Pyogenes , and is classified be a severe form of bacterial sore throat.
