During the complex treatment of patients with dental deformities, 2 clinical groups were identified and the enamel surface was treated with 37% orthophosphoric acid and an erbium dental laser with a wavelength of 2940nm - (power 2 W, water 20%, air 75%, tip: BOOST with nozzle H 6/8, laser beam perpendicular to the enamel at a distance of 5 mm from its surface), before fixing the removable bracket element with orthodontic glue (A16.07.048).&lt;/p&gt;&#13;
&lt;p&gt;The conducted studies have shown that after laser preparation in the etching of enamel with acid, the surface acquires roughness, unevenness with the exposure of numerous micropores, in particular the mouths of enamel channels, which increases the electrical conductivity of enamel and electrometric indicators reach 1.3(0.9; 1.5) mkA from the initial 0.15(0.1;0.2)mkA, whereas after processing the enamel with high-intensity laser light, these values were 0.3 (0.1; 0.4) mkA from the initial 0.15 (0.1; 0.2)mkA, due to the mineral saturation of the interstitial spaces of enamel, the mouths of enamel channels sealed with an organo-mineral complex, which reduces the possibility of its subsurface microbial demineralization.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>electrical conductivity of tooth enamel</kwd><kwd>37% orthophosphoric acid</kwd><kwd>high-intensity laser light</kwd><kwd>enamel channel.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>электропроводность эмали зуба</kwd><kwd>37% ортофосфорная кислота</kwd><kwd>высоинтенсивный лазерный свет</kwd><kwd>эмалевый каналец.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ботова Д.И., Косюга С.Ю.
