Resumo: ABSTRACTObjective: This study compared the color stability of different dental composite resins after prolonged exposure to a coffee solution.Methods: Sixty-four cylindrical discs (10 mm diameter x 2 mm thickness) were prepared using 8 different dental composite resins (n=8, per group). The specimens were first immersed in artificial saliva for 24 h followed by immersion in a coffee solution for 14 days. The assessment of chromatic variation (ΔE) was performed with the aid of a Vita Easyshade Advanced spectrophotometer (VITA Zahnfabrik, Bad Sackingen, Germany). The color of each specimen was calculated based on the L*, a* and b* coordinates of the CIELab system.Results: Grandio SO had the lowest average chromatic variation (ΔE=7.77) after immersion in coffee solution. Durafill VS, Grandio and Z350 XT (ΔE=8.58; ΔE=9.52; ΔE=10.39, respectively) showed similar chromatic variation, with no statistical difference in relation to Grandio SO. However, the other dental composite resins evaluated showed statistically higher values of ΔE compared to Grandio SO, and Enamel HRi (ΔE=20.56) demonstrated the highest chromatic variation.Conclusion: The Bulk Fill and hybrid composite resins from the same manufacturer (Micerium, Avegno, Italy) showed greater chromatic variation than the other composite resins tested. Grandio SO (Voco, Cuxaven, Germany) had the lowest ΔE variation.

O padrão de cada espécime foi medido examinando as coordenadas L*, a* e b* do sistema CIELab.Resultados: A resina composta Grandio SO apresentou a menor média de variação cromática (ΔE= 7,77) após a imersão em solução de café. Semelhantemente, a variação cromática das resinas compostas Durafill VS, Grandio e Z350 XT (ΔE=8,58; ΔE=9,52; ΔE=10.39) que não apresentaram diferença estatística. Todavia, as demais resinas compostas avaliadas apresentaram valores estatisticamente maiores de ΔE em relação a resina Grandio SO, sendo que a resina Enamel HRi (ΔE= 20,56) apresentou a maior variação cromática registrada.Conclusão: As resinas da categoria bulk fill e as resinas híbridas produzidas pelo mesmo fabricante (Micerium, Avegno, Itália) tiveram alterações cromáticas superiores às demais resinas testadas sendo que a resina GrandioSO (Voco, Cuxaven, Alemanha) foi a que apresentou menor alteração de ∆E.Universidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Odontologia de Araraquara Programa de Pós-Graduação em Ciências OdontológicasUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de OdontologiaUniversidade Federal de Alfenas Faculdade de OdontologiaUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Odontologia de Araraquara Programa de Pós-Graduação em Ciências OdontológicasUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de OdontologiaFaculdade São Leopoldo MandicUniversidade Estadual Paulista (Unesp)Universidade Federal de Alfenas Faculdade de OdontologiaTrevisan, Tamara CarolinaGusson JÚnior, MarceloBortolatto, Janaína FreitasPigossi, SuzaneOliveira JÚnior, Osmir Batista DeRicci, Weber Adad2018-11-12T17:27:44Z2018-11-12T17:27:44Z2018-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article15-20application/pdfhttp://dx.doi.org/10.1590/1981-863720180001000023125RGO - Revista Gaúcha de Odontologia.
