plaque formation is associated with a variety of contributing factors: poor oral hygiene, crowding teeth, especially saliva composition and metabolism of the whole organism.Someone stone formed as a teenager, and someone not familiar with it until old age.Stone formation is always preceded by the accumulation of plaque along the necks of the teeth.Especially often its location - the location of the excretory ducts of the salivary glands: the lingual surface of the central lower teeth and buccal surfaces of the upper molars. Content
Leftover food, micro-organisms, their metabolic products are deposited on the surface of the teeth, and when there is insufficient time to clean sealed.Soft plaque has its own independent from the whole organism metabolism, specific flora (Streptococcus mutans), which uses the remnants of food and saliva trace.Plaque on teet
proved negative role of acids produced by plaque germs in the development of caries and periodontal diseases.When cleaning the teeth, a sharp improvement of the oral cavity, reducing the intensity of caries.Different people depending on the composition of saliva and plaque metabolism aggressiveness has a different degree.But one of his property permanently all people - mineralization (hardening) over time.
Cluster of soft plaque, the sticky residue of food, rich in carbohydrates, on the surface of teeth is a predisposing factor.When no qualitative tooth cleaning for several days plaque forms dental plaque (tan "circle" along the necks of the teeth), which has already denser structure and can not always be removed by normal tooth brushing.Constantly getting thicker due to trace elements and minerals, saliva, plaque gives rise to the growth of plaque.If human saliva composition contains an excessive amount of minerals and salts, the risk of stone had increased.
viscosity of saliva also helps to lower the physiological cleansing the surface of teeth.It increases in diseases of the gastrointestinal tract, metabolic disorders, errors in diet.Accumulation of food debris and plaque deposition contributes to malocclusion, close position of the teeth, their overcrowding, substandard fillings or dentures, too soft toothbrush.In any case, the initial stage of the formation of stones - the deposition of soft plaque in suitable locations, the formation of dental plaque.
stone formation can be observed not only on the teeth, but also on the surface of polished enough fillings, dentures.There are over-and subgingival stone.The first type is formed by compacting the soft plaque.Reports from salivary minerals and organic matter contribute to its growth and thickening.The second type relates to stones serum type, ie. E. Formed by plasma proteins and gingival fluid.It is situated under the gum in periodontal pockets.As the thickness of the stone subgingival increasingly pushes the gum from the root of the tooth and helps deepen the pockets.It also seals the admission of minerals from saliva.
For quality cleaning teeth by dense formations necessary to use professional tools and instruments, the procedure must include the following points:
Polishing roots involves the removal of remnants of the stone with the exception of their surfaces and contributing to plaque deposition roughness, unevenness.To remove the stones using hand tools, ultrasonic devices, tools for angle handpieces.Subgingival stones removed kyuretazhnymi spoons or ultrasound, the use of which there is a simultaneous washing areas and gingival pockets with water or antiseptic solutions.After removing the stone surfaces of the teeth are polished with rubber heads, and a special polishing paste.When hypersensitivity after professional cleaning on sensitive areas of the applied solution of sodium fluoride or any means to relieve hypersensitivity recommended gentle non-irritating diet, selected oral hygiene, appointed rinse.
main reason for the growth of the stone - a plaque is compacted about 12 days in the absence of purification.Prevention of tartar deposits is reduced to oral hygiene, regular dental visits for detection of primary education in the form of a plaque.Features food, quality of used brushes and regularity of its replacement, the use of additional hygiene - all these factors influence the rate of formation of stones.Subjectively, they are defined as roughness on gingival of the teeth.On examination of dentition stones isolated as a yellow-brown rims along the necks of the teeth, they can be light with accelerated growth.Regular visits to the dentist can not only help in maintaining the desired level of oral hygiene, but also to prevent the development of gingivitis or periodontitis, one of the causes of which is the formation of tartar.
