Changes in the colour of teeth, both local or general – a very common treatment of patients today cause of the dental clinic. And often, the dentist can remove this discolouration congenital or acquired any noninvasive technique without using the traditional techniques associated with dissection of dental hard tissues.
We have successfully used in clinical practice the following types of non-invasive techniques to remove the discolouration of teeth: microabrasion, composite infiltration, teeth bleaching and remineralisation therapy.
Microabrasion – the most simple and inexpensive procedure for the patient to eliminate «white spots» in enamel hypoplasia and brown stains and fluorosis staining. We use for microabrasion Opalustre (Ultradent), containing as an active component of hydrochloric acid and is a slurry of abrasive particles, which have to handle colour spots and strips it in that location abrasive silicone cups. Held in one visit. Depending on the complexity of the discolouration, the procedure is repeated several times.
Composite infiltration is carried out when the spot lies sufficiently deep in the enamel, and microabrasion capacity not enough to eliminate it. Used ICON (DMG), representing a consistently applied a complex of acid gel, ethanol and direct composite resin that infiltrates the white spot area. In this case, the ICON uses an option to be applied to the vestibular surface of the teeth.
Tooth bleaching – a procedure to change colour once the full dentition. It is widely used today as an independent procedure, and as a patient preparation for prosthetics or extensive direct restorations, as a necessity after the removal of braces.
Remineralisation – a natural process of recovery of teeth enamel defeats without a cavity formed based on the ability of calcium and phosphorus in using fluoride build a new surface on the crystal structure of the residual subsurface layer remaining after demineralisation. These crystals have less acid solubility than the original.
In the last decade we have seen an improvement of interest for the technologies associated with the enamel and dentin remineralisation, and reducing dentin sensitivity, naked, in particular, due to the erosion of the enamel. For remineralising treatmentat, the dentist today has enough arsenal. Actively studied for many compounds for inclusion in remineralising therapy: amorphouscalcium phosphate (ACP), caseinphosphopeptides (CPP), hydroxyapatite, calciumphosphosilicate, tricalcium phosphate (TCP). But the most accessible and logical composition can be considered classic mineral complexes, containing, as basic calcium, phosphorus and magnesium-the most important trace elements for the local recovery of mineral loss of teeth. These minerals, along with xylitol, and became the basis of which show edits clinical effectiveness has been in many works of Russian researchers remineralising gel R.O.C.S. Medical Minerals (DRC, Russia).
Remineralising therapy has now become an important component in aesthetic dentistry and is widely used to enhance the effect of whitening teeth and prolong the result of an office bleaching. For example, when using peroxide-containing bleaching agents natural mechanisms of remineralisation of the teeth are not sufficient to fully restore the structure of enamel, so simultaneously with the course of teeth whitening, we recommend a remineralising therapy. With the combination of bleaching and remineralising therapy achieved a better teeth bleaching that is maintained over a long period of time, by strengthening the enamel and reduce the permeability of the hard tissues of the colouring pigments.
Our studies have shown that the R.O.C.S.Medical Minerals restores the mineral richness of the teeth, increasing the resistance of teeth to decay, improves the colour and lustre of the teeth, reduces tooth sensitivity. Additionally, when using gel R.O.C.S. Medical Minerals 15-30 applications, all patients noted the appearance of teeth whitening and shine.
Today has accumulated considerable experience in the application of the gel applicator R.O.C.S. Medical Minerals in the prevention and correction of chalky spots after orthodontic treatment. The first changes patients notice a week after application of the gel. Expressed-in 30 days of using daily applications of 30 minutes.
It is important to understand that removing teeth discolouration, both local and general will be truly effective only when the right combination of different techniques available today. The most frequently used options are now integrated approach: microabrasion and remineralisation therapy, teeth bleaching and remineralization therapy. And only when the non-invasive methods have not yielded clinical success can be planned the elimination of discolouration usual invasive methods.
