dental caries, predsatvlyava process, destroy the hard dental tissues- email, dentin and cement. At its core is an infectious disease, The most common and widespread chronic disease in humans. It is caused by microorganisms, contained in dental plaque
The early colonizers of the tooth surface are mainly Neisseriaspp. and streptococci, including S. mutans. Growth and metabolism of these types of changing local environmental conditions (pH, koagregatsiya, and accessibility to nutrients), allowing microorganisms with higher requirements for mid to continue the colonization, forming plaque. Together with S. sobrinus, S. mutans plays a major role in tooth decay, metabolizing sucrose to lactic acid. The acidic environment created mouth of this process is the reason, therefor, highly mineralized enamel to be subjected to destruction. Many other sugars - glucose, fructose, lactose, They can be absorbed by S. mutans, they form lactic acid, as the final product. The combination of plaque and acid lead to the destruction of tooth structure.
- genetic factor – the structure of the teeth is genetically predetermined, which in turn determines the susceptibility to the development of caries.
- dental hygiene – Regular brushing (at least twice a day) with appropriate toothbrush, and the use of floss and mouthwash, will minimize the possibility of developing caries. for example, the child is very important to be learned from small to wash your teeth regularly.
- Diet – Nutrition is one of the key factors for creating optimal tooth structure.
Silanization is a preventive method, whose main purpose is to prevent the development of caries. Silanization teeth represent “sealing” special material. This prevents settling of microorganisms, that cause tooth decay.
Procedure of root canal treatment: damaged tooth, opening and cleaning the pulp chamber, expanding channels with endodontic files, root canal filling and placing a crown.
endodontic treatment It is a series of treatments of the pulp of the tooth, resulting in eliminating infection and preservation of the affected tooth from future microbial invasion. These procedures are usually associated with root canal. Root canals and associated pulp chamber are physiological cavities in teeth which are arranged nervous tissue, blood vessels, and other cellular formations. Endodontic treatment involves the removal of these structures, subsequent cleaning, shaping and disinfection of cavities, small saws and irigirashti solutions, and obturirane (fill) channels with gutta-percha and often, kanaloplnezhni mouth bazirani on eugenol.
The situation, where the tooth is considered as endangered (because lesion, breaking or other.), it is probable or imminent possible infection, in order to prevent such an infection is desirable pulpectomy, remove the pulp tissue. usually, some inflammation or infection, already present inside the tooth or below. To cure the infection and save the tooth, dentist reaches the pulp chamber and removes the infected pulp, and then removed from the nerve root canal. Once this is done, dentist fills each of the root canal with an inert material and seals open.
The standard filling material is gutta-percha, natural, rigid latex resin of the tree splurge (Palaquium guys). Standard endodontic technique involves the introduction of gutta-percha pin in root canal cleaned with sealant. Another technique uses molten or heat-softened injected or extruded gutta-percha during root canal. However gutta-percha shrinks as cool, so that thermal methods may be unreliable; sometimes using a combination of techniques. Guta peppering e rentgenokontrasna, allowing the ability to ensure that movements of the root canals are completely filled, without gaps.
Dental restoration or dental filling is a dental restorative material used to restore function, integrity and morphology of missing tooth structure. Structural loss is usually due to caries or external trauma.
Dental restorations can be divided into two types of: direct restorations and indirect restorations. All dental restorations can be even be classified by their location and size.
Right upper first molar, in preparation for sealing. Seen in preparation, white part, enamel look healthy, while the yellow section below, dentin seems to shrink. This is because dentin due to involvement of caries removed. This part of the enamel is now eroded and must be removed to prevent future breakage.
In preparing the tooth for restoration, We need to make a number of judgments, to determine the type and extent of preparation. most- important factor to assess is carious lesions. In most cases, the range of the lesion determine the scope of the preparation and, in turn, process and materials suitable for recovery.
another factor, which must be consistent recovery, undermined the structure of the BNI.
This technique involves placing a soft or malleable material into the prepared tooth and the tooth is built before the material hardens. The advantage of direct restorations is that they are usually placed quickly and can be completed in one visit. When required strength, especially when the seal gets bigger, indirect restoration may be the- best choice.
This is a technique of making the restoration outside the mouth, using dental impressions of teeth prepared. Common indirect restorations include inlays, onlei, crown, bridges and veneers. Usually a dental technician makes indirect restorations fingerprint dentist who provides the prepared teeth. Completed recovery usually cemented permanently with dental cements. It is often carried out in two visits. Often indirect restorations are izryabotvat using gold or ceramics.
As it made indirect restoration, sometimes used temporary restoration, to cover the prepared part of the teeth, which can help maintain the surrounding dental tissue.
Some consider removable dentures to form indirect tooth restoration, because they are made to replace missing teeth. There are many kinds of precision extrusions (also known as combined prosthetics), that support the attachment of removable restorations to the teeth, including magnets, tsangi, hooks and implants.
Materials used in dental restorations
Dental amalgam has been widely used because of ease of processing of the plastic material in a solid direct recovery, completed in a single visit, with acceptable strength, rigidity, corrosion and toxic properties. Mainly used for posterior teeth. Although the mercury in amalgam is not treated free of mercury, doubts about the toxicity of amalgam there by opening it as a dental material. Stopped in countries such as Norway, Sweden, Finland.
With natural color
Dental composites also called white fillings, used in direct restorations. Crowns and inlays can also be made from dental composites. Their strength and durability is not as high as the porcelain or metal restorations and they are more prone to wear and stains.
Voice ionomer cement
Voice ionomer cement is a material mainly used in dentistry, a seal or cementing. These materials are based on the interaction of the glass powder and siliktno polialkenova acid.
Linking chemically to hard dental tissues, release fluoride for a relatively large viewing time. The desirable properties aloud ionomer cements make them useful materials in the restoration of carious lesions in less busy areas.
