Objective: To compare in vitro the surface roughness of a BulkFill composite resin: Aura® BulkFill (SDI) with Tetric N-Ceram® BulkFill resin (Ivoclar Vivadent) when immersed in two rehydration drinks: Sporade® and Gatorade®. Materials and methods: 88 resin specimens divided into four groups were used, with a metal matrix (10 mm x 4 mm). The resins were inserted with a resin spatula, and photo-activated with the Elipar LedTM lamp, with an intensity of 1200 mW/cm2. The specimens were immersed in distilled water. After 24 hours, the roughness was measured with the Mitutoyo SJ-210P rugosimeter. Then, the immersion in rehydration drinks was performed and the final roughness was measured after 7 days. Results: The initial and final roughness of the resins Aura® BulkFill (SDI) and Tetric N-Ceram® BulkFill (Ivoclar Vivadent) showed significant differences after immersion in rehydration drinks. For specimens of Aura® BulkFill (SDI) when subjected to Sporade® an initial mean of 1.20 and a final average of 1.76 was found and the values for Gatorade® were 0.77 and 1.73. While the surface roughness of Tetric N-Ceram® BulkFill (Ivoclar Vivadent) when immersed in Sporade® was 0.82 and 1.55, and in Gatorade® 0.77 and 1.73. When comparing the difference of the final and initial surface roughness (deltas), the Aura® BulkFill resin showed significant differences while, Tetric N-Ceram® BulkFill did not have differences when immersing them in both rehydration drinks. Conclusions: The resins studied increased their roughness after being immersed in the aforementioned beverages.
