При выполнении методики пульпотомии во временных зубах неизбежна контаминация стенок зуба используемой пастой, способная повлиять на адгезию реставрационного материала. Изоляция рабочего поля коффердамом не может предотвратить «загрязнение» поверхности дентина в области эндодонтического доступа.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Изучить влияние МТА-содержащей и частично мумифицирующей пульпу пасты для проведения пульпотомии на прочность адгезионного соединения композитного материала с дентином временных зубов с использованием универсального адгезива.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В настоящем исследовании тестировали современный универсальный адгезив OptiBond Universal с ответствующим фирменным композитным материалом. В исследовании тестировали удаленные по хирургическим показаниям первые временные моляры у детей 6-7 лет. На поверхность субстратов дентина готовых образцов наносили МТА-содержащую и частично мумифицирующую пульпу пасты (1-я и 2-я группы образцов) на 60 секунд, удаляли с помощью ватного ролла. Прочность адгезионного соединения композитного материала – ПАС (Асд) – оценивали согласно ГОСТ Р 51202-98. Морфологическую оценку образцов до и после испытания проводили при увеличении 30, 250, 300 с использованием флуоресцентной микроскопии. Для проверки достоверности различий значений ПАС (Асд) в двух независимых группах использовали U-критерий Манна – Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. Испытания на определение ПАС (Асд) композитного материала с использованием универсального адгезива с дентином временных зубов в 1-й и 2-й группах показали, что экспозиция МТА-содержащей пасты существенно не влияет на показатель среднего значения ПАС (Асд) по сравнению с группой контроля. Однако экспозиция частично мумифицирующей пасты приводит к снижению показателя среднего значения ПАС (Асд) по сравнению с группой контроля на 22%.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. During pulpotomy procedures in primary teeth, the contamination of cavity walls by the applied pulpotomy material is unavoidable and may compromise the adhesion of restorative materials. Notably, the use of rubber dam isolation does not eliminate the risk of dentin surface contamination within the area of endodontic access. Objective. To evaluate the effect of two pulpotomy materials—one containing MTA and the other a non-MTA-based formulation with moderate fixative action—on the shear bond strength (SBS) between a composite restorative material and primary dentin when a universal adhesive system is used.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. This study evaluated a modern universal adhesive system (OptiBond Universal) in combination with its corresponding proprietary composite restorative material. Extracted first primary molars from 6- to 7-year-old children, removed for surgical indications, were used. Two types of pulpotomy materials were applied to the dentin surface of the specimens: an MTA-containing material (Group 1) and a non-MTA-based material with moderate fixative action (Group 2). Each material was applied for 60 seconds and then removed using a cotton roll. The SBS between the composite material and dentin was measured in accordance with GOST R 51202-98. Morphological evaluation of the specimens before and after testing was conducted using fluorescent microscopy at magnifications of ×30, ×250, and ×300. The Mann–Whitney U-test was used to assess the statistical significance of differences in SBS values between the two independent groups.</p></sec><sec><title>Results</title><p>Results. The SBS of the composite material to primary dentin using the universal adhesive in Groups 1 and 2 indicated that exposure to the MTA-containing material did not result in a statistically significant difference in mean SBS values compared to the control group. In contrast, exposure to the non-MTA-based pulpotomy material with moderate fixative action led to a 22% reduction in the mean SBS value relative to the control group.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кариес</kwd><kwd>временные зубы</kwd><kwd>универсальный адгезив</kwd><kwd>адгезионная прочность</kwd><kwd>МТА</kwd><kwd>композитный реставрационный материал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>caries</kwd><kwd>primary teeth</kwd><kwd>universal adhesive</kwd><kwd>shear bond strength (SBS)</kwd><kwd>MTA</kwd><kwd>composite material</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">Garcia IM, Leitune VC, Ibrahim MS, Melo MA, Faus Matoses V, Sauro S, et al.
