How to eliminate tooth decay?The best option - to use a modern filling materials.In dentistry used for this purpose different group of excipients.Selection of a particular composition will depend on many factors: its properties, safety to the body value.Finding your way to help the patient following a brief overview of the materials for dental treatment.
filling material is divided into the following types:
1. Silver amalgam.This material actually has lost its former popularity, obsolete, recently hardly used.It consists of mercury, which is highly toxic vapors.The widespread use of silver amalgam in dentistry was due to a number of advantages: strength, durability, high antibacterial performance, low cost.Significant disadvantages: low adhesion, grinding seals must be repeated visits to the doctor, unsightly, may darken and break away tooth structure, toxicity, loose marginal integrity.
2. Dental cements.Widely used for about twenty years ago.The best filling material from this group, which is still used - glass ionomer cement.Composition: silicon, aluminum, fluorine.Kneaded with distilled water or polyacrylic acid (50% solution).
Advantages:
- hardens quickly - within a few minutes;
- highlights fluorine, promotes regeneration of dental tissues - consists of a mixture ftoralyumosilikata and polyacrylic acid (such a seal is relapse prevention of tooth decay, so the glass ionomer cement is indispensable for the treatment of primary teeth);
- moisture resistance - can be used as an insulating lining that protects the tooth tissue from the damaging effects of aggressive;
- harmless - does not irritate the pulp;
- high adhesion - is able to bind with calcium hard dental tissues.
3. Composite filling materials.The most in demand in recent years.The composite consists of an organic matrix (synthetic resins) and inorganic filler (quartz powder).For the treatment of posterior teeth material is used with larger silica particles to provide the requisite strength for a long term.
advantages of composites:
- resistance to abrasion;
- health safety;
- high strength;
- ease of use;
- perfect polishing;
- the use of a successful restoration of the front teeth;
- high aesthetic properties - filling material maximizes mimic the natural color, texture, transparency, ie,the effect of dry gloss;
- a wide range.
Possible complications:
- sensitivity - occurs in violation of the art treatments, bookmarks, a large portion of the material;
- Quick Erase, loss, if properly selected filling material, and the composite can not be used for the treatment of patients with increased abrasion of tooth enamel;
- tooth decay, however its walls - do not use composite material for restoring a tooth crown destroyed more than 50%.
Thus, the choice of the composition of the seals - cement, metal or polymer -better trust the dentist.It will assess the condition of the teeth and offer the best option for a particular patient.
