DURAN, Gerardo et al. The effect of different finishing and polishing procedures on the surface gloss of Bulk-Fill resin composites. Int. j interdiscip. dent. [online]. 2020, vol.13, n.1, pp.17-20. ISSN 2452-5596.

Statement of the problem:

The literature still lacks evidence regarding which polishing techniques have the ideal clinical outcomes for bulk-fill resin composites.


This study evaluated the surface gloss of two commercially available bulk-fill resin composites after different polishing procedures and characterized their micromorphology via scanning electron microscopy.

Material and Methods:

80 bulk-fill compactable composite resin discs were created. The control group was left untreated, and remaining samples were subjected to different polishing techniques. Gloss units were measured and surface morphology of disc samples was assessed. The Tukey post-hoc test was used to identify any differences.


Statistically significant differences were found between the different polishing systems applied to Filtek BulkFill Posterior and Tetric N Bulk-Fill. No differences were found when the same polishing system was applied for both resins. The highest gloss values were obtained in the control group and the ENA Shiny system; the lowest were obtained with SofLex XT and Soflex Spiral Wheels for the bulk-fill composite resins studied.


Diamond pastes have the highest gloss behavior, followed by diamond rubber points. The systems with aluminum oxide discs present the lower gloss behavior. SEM images provided useful evidence, and future studies should include an evaluation over time.
