“…The presence of trace amounts of metals in human tooth enamel is a natural state 5 , 6 . Among other reasons, this is because enamel consists of minerals from the apatite group in more than 90% of its constitution 7 . These minerals have an extremely flexible crystal structure that allows for a wide range of ionic substitutions in their unit cell.…”

“…Hence, the elements present in saliva can build into their structure 13 – 17 . Therefore, the chemical composition of enamel depends not only on genetic factors but also on age, living environment, and individual dietary and hygiene habits 6 , 7 , 10 , 18 . An imbalance in the process of enamel remineralization and demineralization leads to enamel caries 19 – 21 .…”

Human enamel is composed mainly of apatite. This mineral of sorption properties is susceptible to chemical changes, which in turn affect its resistance to dissolution. This study aimed to investigate whether metal leakage from orthodontic appliances chemically alters the enamel surface during an in vitro simulated orthodontic treatment. Totally 107 human enamel samples were subjected to the simulation involving metal appliances and cyclic pH fluctuations over a period of 12 months in four complimentary experiments. The average concentrations and distribution of Fe, Cr, Ni, Ti and Cu within the enamel before and after the experiments were examined using ICP‒MS and LA‒ICP‒MS techniques. The samples exposed to the interaction with metal appliances exhibited a significant increase in average Fe, Cr and Ni (Kruskal–Wallis, p < 0.002) content in comparison to the control group. The outer layer, narrow fissures and points of contact with the metal components showed increased concentrations of Fe, Ti, Ni and Cr after simulated treatment, conversely to the enamel sealed with an adhesive system. It has been concluded that metal leakage from orthodontic appliances chemically alters enamel surface and microlesions during experimental in vitro simulated treatment.
