Objective The objective of this study was to review the experimental staining procedures performed in in‐vitro studies for evaluating color stability of resin‐based composites used for direct restorations. Overview A review was performed with the purpose to identify in vitro procedures carried out to establish staining and color stability of resin‐based composites used for direct restorations. A literature search was performed on four online databases (PubMed, Scopus, Embase and Web of Science) for articles published from January 1st 2001 till March 20th 2021, using a combination of free words and Medical Subject Headings (MESH) terms: “Composite Resins” AND “Color Stability” OR “Staining.” Two reviewers screened titles and/or abstracts of 1728 unique studies. In total, 208 studies were selected for full‐text reading, from which 178 were included in the review. The assessed variables were specimen dimensions, shape, and surface finishing; time before immersion; staining media type, dwell time, temperature and renewal interval; type of composite; color and translucency assessment parameters and measuring system. One hundred and seventy‐eight articles analyzed color stability with staining liquids. Coffee was the most used staining medium (n = 102), followed by tea (n = 61), and red wine (n = 55). A disc‐shaped specimen was used in most studies (n = 170) with a 2 mm thickness (n = 116). Spectrophotometers were the most used color assessment devices (n = 154), followed by colorimeters (n = 17). Color differences were quantified with ΔE (n = 154), ΔE00 (n = 23). Acceptability and or perceptibility thresholds were also taken into consideration (n = 126). Conclusions The large variety of staining procedure suggests the need for standardization. Clinical Significance Aesthetic failure due to discoloration is a relevant clinical problem. Evaluating benefits and drawbacks of resin based composites artificial staining procedures will improve to predict materials clinical performances.

“…For S10M3, the high proportion of spherical-shaped Sr/F-nanoparticles (200 nm) may help reduce surface irregularity and improve optical properties [ 20 ], which could reduce the color difference [ 83 ]. The use of MCPM at a low level may also reduce water sorption, affecting the color stability of the materials [ 84 ].…”

Effects of Sr/F-Bioactive Glass Nanoparticles and Calcium Phosphate on Monomer Conversion, Biaxial Flexural Strength, Surface Microhardness, Mass/Volume Changes, and Color Stability of Dual-Cured Dental Composites for Core Build-Up Materials

This study prepared composites for core build-up containing Sr/F bioactive glass nanoparticles (Sr/F-BGNPs) and monocalcium phosphate monohydrate (MCPM) to prevent dental caries. The effect of the additives on the physical/mechanical properties of the materials was examined. Dual-cured resin composites were prepared using dimethacrylate monomers with added Sr/F-BGNPs (5 or 10 wt%) and MCPM (3 or 6 wt%). The additives reduced the light-activated monomer conversion by ~10%, but their effect on the conversion upon self-curing was negligible. The conversions of light-curing or self-curing polymerization of the experimental materials were greater than that of the commercial material. The additives reduced biaxial flexural strength (191 to 155 MPa), modulus (4.4 to 3.3), and surface microhardness (53 to 45 VHN). These values were comparable to that of the commercial material or within the acceptable range of the standard. The changes in the experimental composites’ mass and volume (~1%) were similar to that of the commercial comparison. The color change of the commercial material (1.0) was lower than that of the experimental composites (1.5–5.8). The addition of Sr/F-BGNPs and MCPM negatively affected the physical/mechanical properties of the composites, but the results were satisfactory except for color stability.

“…Essa suscetibilidade da resina composta a alteração de cor se deve ao grau de sorção de água e um dos fatores intrínsecos mais expressivo é a oxidação do monômero ao longo do tempo (Abdallah et al, 2014). Os fatores extrínsecos estão relacionados aos corantes de bebidas e comidas, o pH dessas substâncias, o tempo de imersão e a qualidade de higiene bucal do paciente (Abdallah et al, 2014;Bagheri, et al, 2014;Agnihotry et al, 2014;Tan et al, 2015;Backes et al, 2020).…”

O objetivo desse estudo consistiu em avaliar a estabilidade de cor da resina composta quando submetida a diferentes intensidades de fotopolimerização e substâncias corantes. Foi realizado um estudo in vitro com amostras (n=50) de resina microhíbrida (Spectro Basic, Dentsply Sirona) aleatorizadas em 10 grupos, conforme a distância de fotopolimerização (D1: 0 mm e D2: 8 mm) e as soluções corantes (soro fisiológico, café, suco de uva, refrigerante de laranja e chá). Os dados foram tabulados e analisados por meio do software IBM SPSS. Foram aplicados testes conforme a normalidade (teste de Shapiro-Wilk) e a homoscedasticidade (teste de Levene) e, após essas análises, foi realizado o teste de ANOVA à 1 critério com uma medida repetida, seguido do pós-teste de Sidak. O nível de significância foi fixado em 5%. As diferenças entre a cor inicial e final (ΔWID) foram avaliadas e a mudança de cor foi expressa através do índice de clareamento (WID). O tempo de imersão das amostras nas substâncias foi de 2 meses. Os limites de perceptibilidade e aceitabilidade foram, respectivamente, 0,72 e 2,60 unidades WID. Os valores de psoluções, ptime e pdistância foram significativos (<0,0001). Maiores valores de ΔWID foram observados no grupo refrigerante de laranja (ΔWID = -52,19) e grupo chá (ΔWID -25,23). Concluiu-se que o refrigerante de laranja e o chá foram as bebidas que mais alteraram a cor da resina composta. E a distância de fotopolimerização que obteve a melhor estabilidade de cor da resina foi de 0 mm.
