Resumo: Objective: Evaluation of various bulk-fill composite materials with respect to the microhardness values of the top and base surfaces upon variation in the composite thickness. The effect of aging and comparison of the fluorescence properties exhibited by the materials at different thicknesses will also be examined. Materials and Methods: For all samples, calculations were carried out using a family F probability, with a repeated family design including interactions within and among the factors, which resulted in 135 sample units, with 27 samples per experimental group. Z350, AURA, TETRIC, SDR, and FBF composites were employed with thicknesses of 2, 3, and 4 mm, initially being submitted to microhardness measurements (n=9). Aging was carried out using an aqueous ethanol solution. After aging the microhardness values of the samples were measured again, and a comparative analysis was performed for the fluorescence of all samples. Results: Aging, sample thickness, and the type of material were found to affect both the surface microhardness and the fluorescence values. In addition, the AURA and SDR bulk-fill composites were the least susceptible to differences in thickness in terms of the top and base surface microhardness values. Conclusions: Although the manufacturers of some bulk-fill composites recommend the use of material increments of 4 mm, the results of this study suggest that further research is required before clinical application.

También se examinará el efecto del envejecimiento y la comparación de las propiedades de fluorescencia exhibidas por los materiales en diferentes espesores. Materiales y Métodos: Para todas las muestras, los cálculos se realizaron utilizando una familia de probabilidad F, con un diseño de familia repetida que incluye interacciones dentro y entre los factores, lo que resultó en 135 unidades de muestra, con 27 muestras por grupo experimental. Se emplearon composites Z350, AURA, TETRIC, SDR y FBF con espesores de 2, 3 y 4 mm, siendo sometidos inicialmente a mediciones de microdureza (n=9). El envejecimiento se llevó a cabo utilizando una solución acuosa de etanol. Después del envejecimiento, se midieron nuevamente los valores de microdureza de las muestras y se realizó un análisis comparativo de la fluorescencia de todas las muestras. Resultados: se encontró que el envejecimiento, el grosor de la muestra y el tipo de material afectan tanto la microdureza de la superficie como los valores de fluorescencia. Además, los composites de relleno en bloque AURA y SDR fueron los menos susceptibles a las diferencias de espesor en términos de los valores de microdureza de la superficie superior y de la base. Conclusiones: Aunque los fabricantes de algunos composites de relleno masivo recomiendan el uso de incrementos de material de 4 mm, los resultados de este estudio sugieren que se requiere más investigación antes de la aplicación clínica.Objetivo: Avaliação de várias resinas compostas bulk-fill em relação aos valores de microdureza das superfícies superior e base mediante variação na espessura do compósito. O efeito do envelhecimento e a comparação das propriedades de fluorescência exibidas pelos materiais em diferentes espessuras também serão examinados. Materiais e Métodos: Para todas as amostras, os cálculos foram realizados usando uma probabilidade de família F, com um desenho de família repetida incluindo interações dentro e entre os fatores, o que resultou em 135 unidades amostrais, com 27 amostras por grupo experimental. Os compósitos Z350, AURA, TETRIC, SDR e FBF foram empregados com espessuras de 2, 3 e 4 mm, sendo inicialmente submetidos a medidas de microdureza (n=9). O envelhecimento foi realizado usando uma solução aquosa de etanol. Após o envelhecimento os valores de microdureza das amostras foram medidos novamente, e uma análise comparativa foi realizada para a fluorescência de todas as amostras. Resultados: O envelhecimento, a espessura da amostra e o tipo de material afetaram tanto a microdureza superficial quanto os valores de fluorescência. Além disso, os compósitos bulk-fill AURA e SDR foram os menos suscetíveis a diferenças de espessura em termos dos valores de microdureza da superfície do topo e da base. Conclusões: Embora os fabricantes de alguns compósitos bulk-fill recomendem o uso de incrementos de material de 4 mm, os resultados deste estudo sugerem que mais pesquisas são necessárias antes da aplicação clínica.Research, Society and Development2022-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2593310.33448/rsd-v11i5.25933Research, Society and Development; Vol. 11 No. 5; e36911525933Research, Society and Development; Vol. 11 Núm. 5; e36911525933Research, Society and Development; v. 11 n. 5; e369115259332525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25933/24652Copyright (c) 2022 Lyvia Karla Cerci Ferreira Bertacchini; Poliana Maria de Faveri Cardoso; Brenda Matsunaga Laurindo; Francielle Carneiro Hirata; Júlio Katuhide Ueda; Márcio José Mendonça; Veridiana Camilottihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBertacchini, Lyvia Karla Cerci Ferreira Cardoso, Poliana Maria de FaveriLaurindo, Brenda Matsunaga Hirata, Francielle CarneiroUeda, Júlio Katuhide Mendonça, Márcio José Camilotti, Veridiana 2022-04-17T18:18:56Zoai:ojs.pkp.sfu.ca:article/25933Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:05.904852Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
