Objetivo: Comparar in vitro la rugosidad superficial de resinas Bulk Fill sometidos a diferentes sistemas de pulido. Materiales y métodos: Noventa especímenes de resinas compuestas: Tetric® N-Ceram Bulk Fill (TNC), Filtek™ Bulk Fill (FB) y Opus Bulk Fill (OBF) fueron divididos en 9 grupos (n=10). Cada grupo fue sometido a un sistema de pulido: Cauchos Politip (CP), Discos Sof-lex™ (DS) y Discos Diamond Pro (DDP). La rugosidad superficial inicial y final fue evaluada mediante un rugosímetro. Los datos fueron analizados mediante estadística descriptiva (media ± d.e) y para la comparación de diferencias de rugosidad inicial y final se utilizó la prueba de Kruskal Wallis (p<0.05). Resultados: La rugosidad superficial inicial (media + d.e, CP/DS/DDP) fue: TNC (1.23± 1.30µm/0.94±0.53µm/0.90±0.57µm); FB (0.53±1.29µm/0.59±0.54µm/0.63±0.26µm) y OBF (0.74±0.50µm/0.96±0.62µm/0.65±0.25µm). La rugosidad final fue: TNC (0.19± 0.04µm/0.32±0.23µm/0.28±0.22µm); FB (0.29±0.17µm/0.22±0.19µm/0.25±0.19µm) y OBF (0.15±0.05µm/0.26±0.24µm/0.20±0.14µm). No se encontraron diferencias estadísticamente significativas entre la rugosidad inicial y la rugosidad final TNC (p=0.479); FB (p=0.163) y OBF (p=0.919). Conclusión: Existe una disminución en los valores de rugosidad superficial de las resinas Bulk Fill evaluadas después de ser sometidas a tres sistemas de pulidos. / Aim: To compare in vitro the surface roughness of Bulk Fill resins using different polishing systems. Materials and methods: Ninety specimens: Tetric® N-Ceram Bulk Fill (TNC), Filtek™ Bulk Fill (FB) and Opus Bulk Fill (OBF) were divided into 9 groups (n=10). Each group was polished using a different polishing system: Politip Polishers (PP), Sof-lex Polishing Discs™ (SPD) and Diamond Pro Sandpaper Disk (DPSD). The initial and final roughness were assessed using a profilometer. The results were analyzed using descriptive statistics (mean ±s.d) and for the comparison of differences in initial and final roughness was analyzed using the Kruskal Wallis test (p<0.05). Results: The initial surface roughness (mean ± s.d, PP/SPD/DPSD) was: TNC (1.23 ±1.30um/0.94±0.53um/0.90±0.57um); FB (0.53±1.29um/0.59±0.54um/0.63±0.26um) and OBF (0.74±0.50um/0.96±0.62um/0.65±0.25um). The final surface roughness was: TNC (0.19±0.04um/0.32±0.23um/0.28±0.22um); FB (0.29±0.17um/0.22±0.19um/0.25±0.19um) and OBF (0.15±0.05um/0.26±0.24um/0.20±0.14um). There were no significant differences between the initial and the final roughness measurements: TNC (p=0.479); FB (p=0.163) and OBF (p=0.919). Conclusion: There is a minor decrease in the surface roughness measurements of the Bulk Fill resins after using three different polishing systems. / Tesis
