Aesthetic Dentistry – Cosmetic Dentistry: Aesthetic fillings

Filling materials called compositional materials, or composites belong to this category. These materials can be used both in front teeth and molars, the original form and color can be restored with these.

Being plastical fillings, i. e. they are placed into the tooth in the form a paste, and they harden within the cavity formed in the tooth.

According to their bonding mode, there are two types of composite filling material:
1) one bonds in a chemical way, by reacting with a catalyst,
2) the other with a photopolymerizing effect. In this latter case the filling material is treated with a special blue light, and the material hardens by being exposed to this light.

Due to the favorable mechanical characteristic and special chemical structure a new filling technology is possible.

As opposed to earlier methods, when scraping out the cavity a minimum amount of healthy dentin tissue must be removed in order to ensure a proper position to the filling. This is necessary because of the fact that with the filling we are also applying adhesives, which results chemical bonding processes, too.

Cosmetic dentistry – inlay, onlay

inlayA filling therapy method used on molars, inlays and onlays meet the highest standards of dentistry. The procedure normally starts with a precision mold imprint of the cleared cavity, then a perfectly anatomical and aesthetic inlay is prepared in a dental lab. This is cemented into the cavity by the dentist at a second session.

By its material, they can be of gold, ceramic or composite material.

Root canal therapy

During root canal therapy diseased pulp tissue is removed from the interior of a tooth, and the pulp chamber is thoroughly cleaned and disinfected, and it is filled along the full length of the root canal with material adequate to permanently seal the hollow. Underneath the hard shell of the tooth, or enamel, is the pulp chamber. This contains the blood vessels, nerves and lymph tissue.

Most often the reason for a root canal therapy is the inflammation of the pulp, usually caused by the penetration of bacteria originating from deep dental caries. In such cases bacteria get into the root canal and the surrounding dentin.
By root canal therapy the infected pulp tissue and infected dentin is removed. This is done by special pin-like files.


The steps of the root canal treatment:

1) the infected tooth;
2) opening up of the canals;
3) hollowing out of the canals;
4) the root canal sealed by filling and fitted with a crown.

Dental sealants

The role of dental sealants
The role of dental sealants is to provide the tooth sucseptible to cavities with a protective coating, thus preventing the caries to develop or to take hold. The surface of the molars is rugged and coarse. In the pits and fissures of this surface traces of food may be trapped and combining with the bacteria  would cause tooth decay. In the process of sealing we apply a thin liquid plastic material on the coarse surface of the molars, which material will then spread into the fissures and will harden into a protective layer.

In the case of children this can be applied on the molars, baby teeth or permanent teeth alike. With children assumed to be susceptible to dental cavities it is worth protecting all the permanent molars this way. If, on checking our child’s oral condition we see that the surface of the molars is dark brownish, black, or in any way differing from the other teeth in color, but stll not showing a cavity, this treatment is worth considering, because it is

1) quick,
2) painless,
3) with no drilling,
4) fully tooth-friendly,
5) lastly, it is costs much less then a filling later on.

barazdazaras4The process of preventive sealing

- The tooth is dried with compressed air, and is painted with a colored liquid.
- Shortly after this the liquid will be wiped off, the tooth will be rinsed with clear water and will be dried again.
- The liquid sealant will then be applied, left to seep into the tiniest fissure.
- Following this, if the liquid hardens to light, we will use a high-intensitiy light for 20 seconds, and it is done. If the liquid will react by itself, it would take 1-2 minutes to fully bond.

The “colored liquid” is a type of acid, which, when spread over the tooth, will transform the surface of the tooth enamel into a coarse surface for a very short time. The sealant will catch into this coarse surface when applied. What happens if the acid is spread into places where it should not get? No irreversible harm will be done – in a short while the coarsened enamel surface will repair by itself due to the fluoride and other minerals to be found in the saliva and toothpaste.

The completed sealant will protect the teeth from developing cavities for about 2-3 years, and it constantly emanates fluoride, by which the tooth will be strengthened.  A slightly modified version canalso be applied to premolars and molars of adults. One of the great advantages of the sealants is their capability of enamating fluoride. Bacteria cannot strive in a high fluoride concentration environment, thus on fillings and the surrounding areas.
