Abstract

In our days, tooth discoloration is one of the common problems for people of different age and population groups. This is a fairly common and polyetiological type of pathology of hard dental tissues, which does not have a universal method of treatment. The purpose — study the need to use enamel-sealing liquid on dental tissue after the procedure of chemical teeth whitening.
Materials and methods.
24 teeth extracted for orthodontic indications were used in the experiment. The procedure of chemical teeth whitening was carried out using Opalescence Xtra Boost system. Remineralizing therapy was carried out using enamel-sealing liquid. The elemental composition of enamel and dentin was studied by energy dispersive spectroscopy.
Results.
At traditional bleaching without application of remineralizing preparation and at bleaching with single application of liquid the width of dental tubules markedly increases, thus increasing the permeability between enamel and dentin. With repeated application of liquid, there is a decrease in the width of the dental tubules and hence a decrease in the entrance gate for infection.
Conclusion.
The use of liquid helps to remove organic plaque from the tooth surface, to preserve and replenish the composition of microelements that provide tooth strength, to reduce the width of dental tubules and, consequently, to reduce hypersensitivity of teeth.

Key words:

chemical whitening teeth, sensitivity of teeth, enamel-sealing liquid
