“…A grande parte dos sistemas convencionais de polimento requer o uso de dois ou mais polidores, conceituados como sistemas de múltiplas etapas que possuem os polidores com partículas abrasivas de tamanhos diferentes e que por consequência produzirão efeitos distintos na superfície do material e devem ser usados conforme sequência da maior granulação para menor. Já os sistemas de polimento de um só passo, que também contém partículas abrasivas, promovem o polimento da superfície e diminuem as etapas e o período clínico para o término de uma restauração (3,6,8).…”

Introdução: A rugosidade superficial é definida pela superfície de um material restaurador após as etapas de acabamento e polimento, e é afetada pelas propriedades do compósito resinoso, bem como pelos instrumentos utilizados para a realização do polimento. Objetivos: Avaliar a rugosidade superficial de uma resina composta nano-híbrida polida com diferentes sistemas de polimento por Microscopia de Força Atômica (MFA) e análise dos polidores por Microscopia Eletrônica de Varredura (MEV). Materiais e métodos: Os fatores em estudo são os sistemas de polimento em três níveis: Enhance (Dentsply), Ultra-Gloss (American Burrs) e Dura-Gloss (American Burrs). As unidades experimentais são formadas por 30 corpos de prova em resina composta convencional nano-híbrida, divididos aleatoriamente em 3 grupos (n=10). O Grupo G1 recebeu tratamento com o sistema de polimento de uma única etapa: Dura-Gloss; o Grupo G2, sistema de polimento de múltiplas etapas: Ultra-Gloss; e o Grupo G3 recebeu o tratamento com o sistema de polimento de uma única etapa: Enhance. A variável de resposta quantitativa se dá pela rugosidade superficial avaliada pela Microscopia de Força Atômica (MFA). Resultados: Os resultados obtidos demonstram que os sistemas de polidores Dura-Gloss e Ultra-Gloss apresentaram rugosidade superficial similar entre si (p=0,201) e diferiram estatisticamente do sistema Enhance (p=0,023, Ultra-Gloss e p=0,000, Dura-Gloss), o qual apresentou maior rugosidade superficial para a resina composta nano-híbrida. Conclusão: Os polidores Dura-Gloss e Ultra-Gloss tem maior capacidade de polimento da resina composta nano-hibrida.

Background and Aim: The complications of unwanted surface roughness of composite restorations are highly common due to the increasing use of this restorative material. Therefore, the present study was designed to compare the effect of four finishing and polishing (F&P) tools on surface roughness of microhybrid resin composites. Materials and Methods: This experimental study was performed on 42 samples of CLEARFIL™ AP-X microhybrid composite, which were divided into four groups of different F&P methods and one control group as follows: control (n=2), Flexi-D discs (n=10), Flexi-D + diamond polishing paste (n=10), Intensive twisted rubber polisher (n=10), and Rubber Polisher Teco (n=10). The samples were examined by profilometry. Surface roughness (Ra) of each specimen was measured at three points, and the mean value was considered as surface roughness. The results were analyzed by analysis of variance (ANOVA) and post hoc statistical tests. Results: The surface roughness of composite discs in an ascending order was as follows: control (0.048±0.014 µm), Flexi-D disc (0.179±0.132 µm), Intensive twisted rubber polisher (0.233±0.105 µm), Flexi-D disc with diamond polishing paste (0.232±0.141 µm), and Rubber Polisher Teco (0.251±0.087 µm; P=0.001). The difference between the two groups of Flexi-D disc with diamond polishing paste and Rubber Polisher Teco was not statistically significant (P=0.742). The level of surface roughness in Flexi-D samples was significantly lower than that of the other samples (P<0.05). Conclusion: It seems that the Flexi-D disc is the best F&P tool for microhybrid resin composites.

The objective of this study was to examine the effects of extrinsic or intrinsic acids on nanofilled and bulk fill resin materials in vitro. A total of 90 disks were prepared using dental restorative material (Filtek Z350XT, GrandioSO, Filtek Bulk Fill, X‐tra fil). Thirty disks of each material were sub‐divided into three groups (n = 10) that were immersed for 7 days in deionized water (DW), 5% citric acid (CA—pH 2.1), or 0.1% hydrochloric acid (HCl—pH = 1.2). Surface hardness and roughness (stylus profilometer by Ra parameter) analysis were performed before and after immersion. Morphological changes were evaluated by scanning electron microscopy. The data were analyzed by two‐way ANOVA and Tukey's test (α = 0.05). All tested materials did not show significant differences in the effects of the DW, CA, or HCl solutions on surface roughness (p = .368). Likewise, the hardness loss was not affected by the solutions tested (p = .646), but there was a difference in the resin type (p = .002). Filtek Bulk Fill resin hardness was less affected, while Filtek Z350XT and GrandioSO presented the most hardness loss after 7 days of solution immersion. In terms of this experimental study, the results demonstrate the effectiveness of the mechanical properties (roughness and hardness surface) of nanofilled and bulk fill resin materials to resist erosion from extrinsic and intrinsic acids, therefore being potential candidates for dental applications.
