Tooth decay treatment is vital in dentistry because diseases of hard tissues of teeth lead to all the complications of teeth treatments. It requires exploring and solving these problems at an early stage, but also treatment of more serious conditions which are the roots of endodontics and prosthodontics. Here takes place treatment of caries, uncarious defects of teeth – attrition, erosion, abrasion, and dental injures also (enamel or dentine injures).
The influence of tooth decay process depends on the depth and size of lesion (1, 2, 3, 4 and more missing surfaces) and determines the labour-intensity of follow up treatment.
We offer teeth recovery in two basic methods – by plastic materials and by laboratory imprinted obturations. First group includes amalgam and white fillings – photopolymers – PC (photo composites), chemopolymers – CC (chemo composites), glass ionomers and others.We do not work with amalga –it has only social value because it is not aesthetic, has side effects, and can also leads to secondary tooth decay or broken teeth.
Basic method of this procedure is using photopolymers as layers which takes more time and resources than amalgam, but they react chemically with teeth which guarantees longer lifespan.Treatment starts with anaesthesia( needlestick place is sprayed with lidocaine to ease the process),cleaning of caries. This process does not require retention form. We prefer total etching – enamel and dentine are treated with acid which makes surfaces get more rugged and expand. Then bonding agent is placed, is polymerized by photopolymeric lamp, which has high intensity ultraviolet spectrum. If the tooth is over sensitive or pink pulp is visible, thin layer of glass ionomers or calcium hydroxide is placed. This procedure protects tooth nerves. Afterwards, step by step we place the PP which is exposed to lightning so it can get hard completely. If tissue walls are missing we place metal or lodine die ( something like precise cast ).Final stages include finishing and polishing surfaces – in order for better quality, smooth and shiny result. Otherwise micro leaking is possible, which is the main cause of follow up tooth decay.
*PH-P fillings of back teeth – hybrids – more resistant of digestive movements
*PH-P fillings of front teeth – micro fillings – more precised polished for bigger glitter.
These are again white fillings which get hard without lightning – by combining two even parts. These fillings are easier to work with because they are single placed. They have bigger particles and for that reason can not be polished like PH-P ones, and this leads to slight change in color after time.Their strength is suitable for back teeth.
These are white filling that are not etched, which eases the process – they are suitable for difficult areas like tooth cervix(next to gum).We use them for children teeth, where acid etching is not suitable and can lead to over sensitivity and even teeth los. These fillings are less durable than PH-fillings and Ch-P-fillings.
These indirect fillings (like these mentioned above) are produced by very precise silicone imprint made in laboratory. They are suitable for bigger losses of teeth tissue, which are more difficult to treat only by a dentist. These fillings are model based by special wax, then are mould by preferred alloy – white or based.The first one is recommended because of its biological resistance, it does not make allergic reaction, it is more aesthetic looking, but its cost is more than of a cobalt-chrome one. Placement of these fillings requires upper open canals. Here comes the common mistake of boring healthy teeth structure. It takes only upper open build canal. These IRCs are fixed to teeth by concrete by choice, remains are removed and occlusion and articulations are amended. These mechanisms differentiate by its durability and quality, but are more expensive than office-made ones because they are produced in a laboratory. Technical flaw is their visibility, that is way they are used for back teeth.
