TTR is the control of the doctors there are two types to choose from: TTR TTR at home and in their offices. Each format has its advantages and disadvantages. At present, the TTR measures are based on the principle of fertility is the application of oxygen and oxidation of Hydrogen Peroxide (HP). The authors suggest that HP is a low molecular weight, should be able to diffuse through the enamel and dentin. HP is unstable and easily decompose into free radicals are very active. The main radical oxidation of this bridge, or the original color of the pigment in the dental tissues, decomposing them and thus brighter teeth.

TTR for good results in 95% of stains caused by externalities, such as that in the elderly dark, staining due to filling, due to tooth decay, certain drugs, dental trauma, dead pulp … Particularly for stains caused by internal factors, such as infected teeth tetracycline, fluorosis … very different effect depending on the severity of infection, the response of the teeth and the duration of treatment.

Bleaching at home

Bleach teeth with carbamide peroxide concentrations commonly used 10%, 16%, or 22% Carbamide peroxide exposure … saliva will decompose into HP and urea.Chlorine bleach may lower the effective concentration of the slower but less likely to cause more sensitivity.

Bleaching process at home:

In-office whitening

Previously, the TTR in the form of clinics provide HP with a tray containing a high concentration of 30 to 38% and house sitting in a chair for about 1-2 hours. Later, bleach is usually placed directly on the tooth surface without carrying tray bleaching.

TTR in the office used a device support to promote free radical reaction of HP. May simply be an ordinary light bulbs for the purpose of creating heat, or modern than halogen lamps, LED (Light Emitting Diode), and recently the high-end devices such as laser lights, plasma lights … allows for very high energy source with the appropriate wavelength: result, it has shortened the duration of treatment is only 30-45 minutes and is described under the term “in-office QUICK TTR”.

TTR fast process in the office:

Remove calculus and polishing; Place protective gum tree balls and mouth; for patients to wear eye protection; Set to that medication and phototherapy. Each set of drugs and phototherapy called a cycle. Showtimes and some screen time in each cycle varies according to type of lamp. For example: halogen lamps 20-40 seconds / time / dental x 3lan / cycle; LED (LumaCool) 8 min / 2ham; light laser (LaserSmile) 15giay / time / 4rang; plasma lamp (Apollo Elite) 3 seconds / time / dental x 3lan / cycle.

Apollo Elite can Lamp Total transmission parts and power supply plasma shape so that the front teeth of both functions are shown at the same time, screening time is considerably shortened, just 2 minutes / time / 2ham x 3 times / cycle.

Besides both forms of TTR functions as above, there are forms of selective removal of one or several teeth or only on a portion of the tooth (such as cervical …). This measure is commonly prescribed for staining the teeth with dead pulp stock or dark teeth.

Where on an area of the tooth bleaching, bleaching process is the same as above but only where necessary to bleach white. Where the dead pulp bleaching, endodontic treatment that should be good, and the doctor will perform a special process to HP be placed both outside and inside the tooth and still ensure that the tip does not cause irritation.
