According to a new study in Acta Odontologica Scandinavia, researchers have said that sugared soft drinks and juices do not appear to degrade the physical and chemical properties of nickel titanium orthodontic wires.
According to a recent report, researchers from the University of Bologna evaluated the effect of Coca Cola, orange juice, and Gatorade on the Young’s modulus, hardness, surface topography, and chemical composition of nickel-titanium-based orthodontic wires.
The report stated that the researchers cut 32 specimens (20mm in length) from the straight portion of performed 0.019 x 0.025-inch nitinol heat-activated archwires and randomly divided into four groups of eight specimens each: Group A1 (Coca Cola) regular), Group A2 (Santal orange juice), Groups A3 (Gatorade), and Group B (distilled, deionized water). Each specimen was immersed in 10mL of one of the soft drinks or the control for 60 minutes at 37?C.â€
The study concluded that there were no significant differences between the groups either in the young’s modulus or hardness after the selected soaking protocol.
besides some surface colour changes, the topography and the chemical composition of the wires were not affected by the immersion in any of the chosen soft drinks, they noted.
