    The objective of this study was to determine the chromatic stability in nano-hybrid resins with and without polishing from two different brands, immersed in pigmenting solutions. The methodology used was inductive, with a quantitative, experimental, longitudinal, and prospective approach. Two pigmented beverages were used: a carbonated beverage and purple corn drink. A total of 80 resin discs were used, divided into 10 discs of each brand, with polishing and without polishing (3M Z350 XT and Tetric N-Ceram). These resin discs, with a diameter of 10mm and a thickness of 2mm, were immersed for 10 days in containers with the carbonated beverage and purple corn drink. The Sof-Lex disc system (3M) was used for polishing the resin discs. All measurements were taken using a Chromascop colorimeter, and the data collection instrument was validated by experts. The results showed that polished resin discs of the 3M Z350 XT and Tetric N-Ceram brands, immersed in carbonated beverage, underwent a color change of 2 shades, while non-polished resin discs of the same brands experienced a color change of 5 shades. This study concluded that the chromatic stability of both 3M Z350 XT and Tetric N-Ceram resins, whether polished or not, changes when exposed to pigmented beverages. It was also concluded that polishing the 3M Z350 XT and Tetric N-Ceram resins is a crucial factor in maintaining better chromatic stability.
