Changes In The Salivary Flow

Soft and hard tissue healthiest, where saliva flows freely. If we bread or other starchy foods contain carbohydrates, they eat not easily dissolve in saliva and block natural flow of saliva. To protect freedom, all parts of the mouth, saliva contains amylase, an enzyme that breaks starch into sugar, which the mouth clearly and re-establish a path for the flow of saliva.
Xerostomia

Dry mouth or xerostomia, is a chronic reduction in salivary flow. It can result in altered taste, difficulty chewing / swallowing and rampant caries. Without saliva flows suffer the tissue in the mouth, suffer much in the same way the body tissue when blood flow is disturbed.


The treatment of dry mouth
Besides chewing sugar-free gum, commercial products such as artificial saliva, and tissue fluids are also to relieve dry mouth symptoms. If symptoms persist dry mouth, see your doctor to rule out a possible underlying disease.
Causes of reduced salivary flow

Prescription and nonprescription medications often cause reduction in salivary flow. Nearly eighty percent of the most commonly prescribed medications cause dry mouth. After radiotherapy and chemotherapy, the function of the salivary glands is often lost. Some systemic diseases such as Sjogren's syndrome, also compromises salivation.
Saliva is a diagnostic fluid

Because saliva is a bit like blood, it is increasingly used in the evaluation of systemic health. The U.S. National Institutes of Health have salivary diagnostics as an important area of ??development and explore the many specific applications. The advantages of saliva as a diagnostic fluid, based on the blood, ease of collection, their infectious nature and the cost-effectiveness of the test.



Salivary glands of Diagnostic Tests
 A common use of salivary diagnostics for the detection of viral infections, especially HIV. The researchers also report promising results in the use of saliva for the diagnosis of breast cancer, oral cancer and viral hepatitis.

Saliva is an efficient indicator of recent drug use. Portable salivary tests for the detection of therapeutic and abused drugs is available. Saliva has also used with some success in monitoring the response to the treatment of anxiety and depression.

Saliva acts as the bloodstream of the mouth and provides nutrients, elimination of waste, to protect against foreign bacteria and constantly mineralizing enamel. If you are experiencing health problems such as salivation caries and gum disease is reduced. Health professionals are using saliva for early diagnosis of many systemic and metabolic diseases.

The fluoride reservoir

Fluoride promotes remineralisation: the formation of a fluoride reservoir from Aquafresh Science Academy on Vimeo.
Only micro-amounts of fluoride are required to have an influence on the re-and demineralization process occurring on the enamel surface have. Immediately after brushing with a fluoride toothpaste, fluoride levels in saliva increases. Fluoride-ion-binding lightly with calcium ions is always present on tooth surfaces and in saliva. According to a recent fluoride application, a "reservoir" of calcium / fluoride-like forms precipitates in the mouth. These rains are stored in the board and on the enamel surface. The amount of rainfall is considered as the "reservoir of fluoride." Occurs as plaque acid, the calcium / fluoride material dissolves in the container before the tooth enamel, fluoride, exactly when and exactly where it is needed.
Saliva

Saliva is the mouth of the primary defense against tooth decay. Research has shown that fluoride lost to decay by promoting the ability of saliva minerals, the enamel can again prevent cavities from developing, works. Saliva increases the protection of tooth enamel by providing high levels of calcium and phosphate ions at the tooth surface. The presence of these ions slowing demineralization and promote remineralization of tooth enamel constantly. The best explanation of how fluoride works is that it increases the natural remineralizing properties of saliva.
Saliva, fluorides and diet

Fermentable carbohydrates (starch and sugar cooked), in the wide range of foods we eat also offer food for the bacteria that live in plaque. Organic acids that dissolve produced by the plaque biofilm as a byproduct of their metabolism causes the enamel surface. Most of the time we eat there is an acid attack on the enamel surface. Interestingly, more sugar is contained in a food, not create more bacterial acid. Since even small amounts of sugar or starch, will lead to similar acidic conditions, that lists of foods that are "good" or "bad" for the teeth is difficult. Today, most try to advice, the frequency of eating between meals and at the same concentration levels of fluoride daily moderate.

Brush twice a day helps with a fluoride toothpaste to the effects of frequent snacking neutralized by saliva to improve the ability to prevent or repair early tooth decay. Excessive snacking between meals causes dental caries. (Daily for three to four times) by snacking in moderation, one limits the frequency of acid attacks and enables salivary fluoride improved in order to receive e-mail integrity maintained.

Chewing gum after a snack or a meal stimulates saliva flow, clearing food from the mouth and neutralizes plaque acid. Chewing gum stimulates saliva production by up to 10 times the normal rate. Stimulating salivary flow changes the chemistry of saliva. Stimulated saliva contains higher concentrations of bicarbonate, it helps to fight plaque and tooth decay buffer.
Reduced saliva flow

The importance of saliva is really appreciated when saliva flow is reduced. Wherever salivary flow decreased caries and erosion are expected. About 20 percent of adults occasionally to reductions in salivary flow. Common symptoms include persistent dry mouth, pain, difficulty chewing, tasting, speaking and swallowing. Problems with dentures to increase when the mouth is constantly dry. Programs can maintain daily chewing salivary glands starting the day ..
Saliva does not mix well

Saliva from the major salivary glands, and also produced in the tissues of the inner lip and soft palate. Surprisingly, salivary glands from various acts do not mix well in the mouth. Saliva in the back of the mouth secreted not reached the front, and there is little movement of saliva from side to side. Because saliva is not good to mix and its mineral content and buffering capacity differs from gland gland specific sites are therefore more susceptible to tooth decay. Secretions from the small mucous glands in the upper lip, for example, lacks the ability to buffer acid and have a very low mineral content, which may help remineralization. This is one reason why the upper front teeth are as susceptible to dental enamel demineralization. Muscle movements associated with chewing help change the direction of flow of saliva and mixed saliva from different glands.

Salivary glands Film Velocity
When saliva flow increases salivary glands film speed increases. This increases the cavity prevention through faster clearing leftover food with carbohydrates. Persons with unstimulated, low speed saliva swallow less efficient and clear sugar from the mouth of a lot slower. Such people are prone to erosion and decay.

Saliva is the most important protection against the loss of tooth surfaces, and its minerals calcium and phosphorus, the integrity of the enamel surface. To reductions in acidic conditions cause salivation and subsequent email demineralization. Small amounts of fluoride in saliva-enamel junction to increase the maintenance of the enamel structure. Fluoride is stored in a "reservoir" on the teeth and in plaque in the form of calcium / fluoride-like deposits. In an acid attack, the calcium / fluoride material is readily soluble, fluoride, when and where it is needed. Since most foods contain sugar or starch, it can lead to plaque acid when eaten. Chewing on a snack or a meal stimulates saliva flow, preventing increase of the cavity properties.

Influence of Saliva
Saliva plays an important role in developing and maintaining a healthy biofilm. Proteins from the saliva can be attached to the biofilm on the tooth surface. After a dental cleaning, its enamel surfaces coated with a salivary gland protein fast film, the cuticle. The membrane supports the attachment of free-floating bacteria (plankton) that the first settlers are a new biofilm. As bacteria begin to attach to each other, they pave the way for the cultivation of other bacteria in a specific order and pattern. In the course of about three days, a biofilm grows to maturity, it depends primarily on the food and saliva for the elimination of waste. As the biofilm approaches maturity, there are planktonic bacteria in the saliva again. Saliva then transports these sites freely floating bacteria that form where a new biofilm.

Passive and active immune proteins in saliva regulate the growth and movement of the plaque biofilm. There is strong evidence today that the microbes and the immune system work together and develop them as a team to prevent the visit of microorganisms residing in the mouth. The mature biofilm is also dependent on salivary flow. If the flow rate reduces the number of organisms and structures within the biofilm change, in which often lead to inflammatory changes in the supporting tissue.
