Caries Ц is chronic process connected with demineralization and softening of hard tooth tissues with following defect creation (cavity). Caries has 4 phases. The first one is the phase of white spot, it is first phase of caries and in rare cases can be reversible thanks for fluorine drugs. As the surface of tooth doesnТt have damages, the process goes without symptoms.
The second, the third and forth phases - superficial caries, median caries and deep caries. there is appeared cavities of different deep on the surface of tooth. Also it can to became apparent like painful sensation for chemical (sweet and sour), temperature (cold) and mechanical stimuli (ingress of food in carious cavity).
There are following anatomic parts of tooth:
- The crown is what you see when you smile or open your mouth. It's the part that sits above your gum line. ItТs covered by enamel;
- The gum margin (neck) - is the area between the tooth crown and the root;
- The root - is the part of the tooth under the gums and inside the alveolar bone that keeps the tooth in place.
The caries is treated by defected part of tooth excision and then fill up it by filling material (inlay, veneer). Mainly, the patients are interested in quality of materials, which are used in caries treatment. We want to sure You that we are using high-quality materials of such famous brands as Dentsply, 3M, Kulzer, Kerr and so on. So what materials are used nowadays in stomatology? Until recently, it was cements of different composition (has poor colors, week adhesion and high fragility), composition of plastic and composition of first generation (fast change color and high dental abrasion) and amalgam ( has high durability and longevity, but hasnТt any esthetic. Nowadays generation of filling materials (light-cure filling) almost hasnТt past defects: it has high adhesion, high mechanical durability, color-stable, low dental abrasion. In addition, the variety of materials allows dentist to recreate lack part of tooth or whole tooth and make it more natural. Cements also are popular because of their improved quality. ItТs used extensively in childТs dentistry thanks their low toxicity, in adult dentistry as base for light-cure filling, and also in the small carious cavity without masticatory load.
Also we want single out group of tooth injury which are not connected with caries, because of a lot of our patients come with such problems in clinic. There are abrasion and wedge-shaped defects. Abrasion usually can be found on masticatory surface of lateral teeth and cutting ends of frontal teeth. Usually, if it doesnТt bother patient (pain, esthetic) so there is nothing to do. Sometimes for smoothing of denture and improving esthetic and if sharp ends of teeth injure tongue and lips, the uneven erased teeth are levigated. If patient isnТt satisfied by esthetic of tooth or considerable part of tooth is lost, in this case the erased tooth can be extended by filling materials, inlays, veneers and crowns. The second type of pathology is wedge-shape defect. It gets this name because of shape (wedge). It is placed on the outside of tooth at the neck area. The reason of it is wrong transversal motion of toothbrush to tooth, and too strong pressure of brush on teeth. Very often, this type of pathology doesnТt have any symptoms, and patients see only worsening of outside of teeth. With the laps of time, wedge-shaped defects are increased, and as in result, nerve can be infected. Also, as result there is can appeared caries if level of hygiene of cavity is lowering. On the early stage, for treatment there is used fluorine preparations and teaching of hygienic rules. On the advanced stages, there are used filling of cavity and crown in the rear cases.
