OBJECTIVE
The effect of orange juice and Coca Cola(®) on the release of metal ions from fixed orthodontic appliances.
MATERIALS AND METHODS
A continuous flow system designed for in vitro testing of orthodontic appliances was used. Orange juice/Coca Cola(®) was flowing through the system alternately with artificial saliva for 5.5 and 18.5h, respectively. The collected samples underwent a multielemental ICP-OES analysis in order to determine the metal ions release pattern in time.
RESULTS
The total mass of ions released from the appliance into orange juice and Coca Cola(®) (respectively) during the experiment was calculated (μg): Ni (15.33; 37.75), Cr (3.604; 1.052), Fe (48.42; ≥ 156.1), Cu (57.87, 32.91), Mn (9.164; 41.16), Mo (9.999; 30.12), and Cd (0.5967; 2.173).
CONCLUSIONS
It was found that orange juice did not intensify the release of metal ions from orthodontic appliances, whereas Coca Cola(®) caused increased release of Ni ions.
目的
研究橙汁和可口可乐对固定正畸矫治器金属离子释放的影响。
材料与方法
采用一种为正畸矫治器体外测试设计的连续流动系统。橙汁/可口可乐分别与人工唾液交替流经该系统5.5小时和18.5小时。对收集的样本进行多元素电感耦合等离子体发射光谱分析，以确定金属离子的实时释放模式。
结果
计算出实验过程中矫治器释放到橙汁和可口可乐中的离子总质量（微克）：镍（15.33；37.75）、铬（3.604；1.052）、铁（48.42；≥156.1）、铜（57.87，32.91）、锰（9.164；41.16）、钼（9.999；30.12）和镉（0.5967；2.173）。
结论
研究发现，橙汁不会加剧正畸矫治器中金属离子的释放，而可口可乐会导致镍离子释放增加。
