BACKGROUND: The clinical testing of composite materials existing on the market is necessary for their further improvement.

AIM: This prospective blind, randomized study of the clinical effectiveness of the nanocomposite most commonly used in practical dentistry aimed to evaluate the effectiveness of restorations based on clinical characteristics, according to the Federation Dentaire Internationale criteria, characterizing the quality of direct restorations of localizations of Black classes I–IV, made from nanofill composites EsCom 250 using the V generation EsBond adhesive.

MATERIALS AND METHODS: A total of 125 patients were examined, and 36 patients had 72 restorations placed in accordance with the criteria. The safety of the restorations was assessed after 3, 6, and 9 months, as well as the level of retention (safety of restorations). The composite nanohybrid material EsCom 250 was placed with EsBond adhesive using the total etching technique. Statistical analysis was performed with the treatment protocol according to CONSORT. Differences in the ratings of the three groups at 6 and 9 months were tested using Friedman repeated-measures analysis of variance by rank (α = 0.05).

RESULTS: The main clinical criterion was retention/defect, and the safety rates were as follows: 96% (87%–99%) for Black class I, 98% (90%–100%) for class II, 98% (90%–100%) for classes III and IV, 94% (84%–98%) for class V. However, no statistical differences by Black class were found at 6- and 9-month examinations (p > 0.05).

CONCLUSION: The degree of preservation of restorations (87%–99%) during 9 months of observation was high. EsCom 250 can be recommended for use in patients diagnosed with dentin caries in the primary health care setting in a state budgetary dental clinic.

Актуальность. Клиническое тестирование существующих на рынке композиционных материалов необходимо для их дальнейшего совершенствования.

Цель — проспективное слепое, рандомизированное исследование клинической эффективности наиболее часто используемого в практической стоматологии нанокомпозита. Оценка эффективности реставраций по клиническим характеристикам, согласно критериям FDI, которые определяют качество прямых реставраций локализаций I–IV классов по Блэку, выполненных из композиционого нанофильного стоматологического материала EsCom 250 с использованием адгезива V поколения EsBond.

Материалы и методы. Осмотрено 125 пациентов и в соответствии с критериями размещено 72 реставрации у 36 человек. Проведена оценка сохранности размещенных реставраций через 3, 6, 9 мес. Уровень ретенции (сохранности реставраций), композиционным наногибридным материалом EsCom 250, размещенный с адгезивом EsВond в технике тотального травления. Статистический анализ проводился с протоколом лечения в соответствии с CONSORT. Различия в рейтингах групп через 3, 6 и 9 мес. были проверены с помощью анализа повторных измерений Фридмана, дисперсия по рангам (α = 0,05).

Результаты. Основной клинический критерий — ретенция/дефект, сохранность составила 96 % (87–99 %) для I класса по Блэку; 98 % (90–100 %) для II класса; 98 % (90–100 %) — для III и IV классов по Блэку; 94 % (84–98 %) — V класс; без статистической разниц по классам по Блэку, при осмотре через 6 месяцев и через 9 мес. (p > 0.05).

Заключение. Степень сохранности реставраций (87–99 %) в течение периода наблюдений в 9 мес. высокая. EsCom 250 может быть рекомендован к использованию при оказании первичной медико-санитарной помощи с диагнозом кариес дентина, в условиях государственной бюджетной стоматологической поликлиники.
