Для приготовления образцов использовали удаленные зубы без кариозных повреждений и больших пломб. Образцы 60 зубов были разделены на 2 группы (n=30) с использованием лака и без. В каждой группе исследовалась адгезионная прочность на сдвиг до и после термоциклирования (n=15). Применялись следующие материалы: двухкомпонентная самоотверждаемая стоматологическая адгезивная система Universal Bond II (Tokuyama Dental), лак SHIELD FORCE PLUS (Tokuyama Dental), адгезивный фиксирующий цемент двойного отверждения ESTECEM II PLUS (Tokuyama Dental). Испытания адгезионной прочности на сдвиг подготовленных образцов проводили на универсальной испытательной машине «SYNTHEZ 5» при скорости движения траверсы 5 мм/мин согласно методике ГОСТ Р 56924-2016 (п. 7.15).</p></sec><sec><title>Результаты</title><p>Результаты. Показатель адгезионной прочности контрольной группы (до термоциклирования) составил 4,33±1,28 МПа, в основной подгруппе (после термоциклирования) 3,48±0,81 МПа. Наличие лака на поверхности эмали не повлияло на адгезионную прочность склеивания брекет-системы и ткани зуба и составило 4,50±0,25 МПа и 3,14±0,82 МПа соответственно (р=0,0005).</p></sec><sec><title>Выводы</title><p>Выводы. Наличие лака на поверхности эмали не повлияло на адгезионную прочность соединения брекет-систем с тканями зуба в контрольной (до термоциклирования) и основной (после термоциклирования) подгруппах (р≤0,05). Показатель адгезионной прочности в контрольных подгруппах (до термоциклирования) и основных (после термоциклирования) обеих групп различался незначительно. Термоциклирование снижает адгезионную прочность брекет-систем с тканями зуба при использовании универсального адгезива Universal Bond II (Tokuyama Dental) (р≤0,05).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. At the present stage, the choice of high-quality adhesive material is an important task of dentistry. The choice of the ideal adhesive material remains an urgent task to this day.</p><p>The aim of the study was to study in laboratory conditions the adhesive shear strength for fixing ceramic braces of a universal adhesive system containing 3D-SR monomer (Universal Bond II (Tokuyama Dental)) and adhesive cement ESTECEM II PLUS (Tokuyama Dental) before and after thermal cycling, with and without the use of varnish.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. For the preparation of samples, removed teeth without carious lesions and large fillings were used. Samples of 60 teeth were divided into 2 groups (n=30) with and without varnish. In each group, the adhesive shear strength was studied before and after thermal cycling (n=15). The following materials were used: two-component self-curing dental adhesive system Universal Bond II (Tokuyama Dental), varnish SHIELD FORCE PLUS (Tokuyama Dental), adhesive fixing cement double curing ESTECEM II PLUS (Tokuyama Dental). Tests of the adhesive shear strength of the prepared samples were carried out on a universal testing machine «SYNTHEZ 5» at a traverse speed of 5 mm/min according to the methodology of GOST R 56924-2016 (р. 7.15).</p></sec><sec><title>Results</title><p>Results. The adhesive strength index of the control group (before thermal cycling) was 4.33±1.28 MPa, in the main subgroup (after thermal cycling) 3.48±0.81 MPa. The presence of varnish on the enamel surface did not affect the adhesive strength of the bonding of the bracket system and tooth tissue and amounted to 4.50±0.25 MPa and 3.14±0.82 MPa, respectively (p= 0.0005).</p></sec><sec><title>Conclusions</title><p>Conclusions. The presence of varnish on the enamel surface did not affect the adhesive strength of the connection of the bracket systems with tooth tissues in the control (before thermal cycling) and the main (after thermal cycling) subgroups (p≤ 0.05). The adhesive strength index in the control subgroups (before thermal cycling) and the main ones (after thermal cycling) of both groups differed slightly. Thermal cycling reduces the adhesive strength of braces with tooth tissues when using universal adhesive Universal Bond II (Tokuyama Dental) (p≤ 0.05).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>адгезивная система</kwd><kwd>адгезионная прочность на сдвиг</kwd><kwd>универсальный адгезив</kwd><kwd>керамические брекеты</kwd><kwd>фиксация керамических брекетов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>аdhesive system</kwd><kwd>adhesive shear strength</kwd><kwd>universal adhesive</kwd><kwd>ceramic braces</kwd><kwd>fixing ceramic braces</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Суслова О.В., Желизняк Н.А., Стеценко Д.В., Кордонец Е.Л., Анисимов М.В.
