Effect of three beverages on the micro-strength of a composite resin: in vitro study
(Universidad Privada Norbert Wiener, 2019-08-15) Gómez Vásquez, Katty; Vilchez Bellido, Dina
The objective of this research was to compare the effect of three beverages on the microhardness of a composite resin in an in vitro study. The study was experimental, longitudinal, comparative, and prospective, with a comparative level, consisting of a sample of 10 composite resin discs per group, which were immersed in four immersion liquids, totaling 40 (n=40). The beverages used were an energy drink (Volt), a carbonated drink (Guaraná), a hydration drink (Gatorade), and as a control group, physiological serum. The results showed that the composite resin subjected to the energy drink Volt had an initial microhardness of 76.27 ± 4.74 Kg/mm² and a final microhardness of 70.04 ± 3.92 Kg/mm²; the composite resin subjected to the carbonated drink Guaraná had an initial microhardness of 77.04 ± 2.69 Kg/mm² and a final microhardness of 73.32 ± 3.59 Kg/mm²; the composite resin subjected to the hydration drink Gatorade had an initial microhardness of 78.48 ± 5.33 Kg/mm² and a final microhardness of 70.96 ± 2.18 Kg/mm²; while the composite resin subjected to physiological serum had an initial microhardness of 80.06 ± 3.48 Kg/mm² and a final microhardness of 70.15 ± 2.60 Kg/mm². A statistically significant difference was found between the initial and final microhardness of the composite resin subjected to the energy drink Volt, hydration drink Gatorade, and carbonated drink Guaraná (p<0.05). Conclusion: A variation between the initial and final microhardness of the composite resin was observed when subjected to the different beverages studied.
