“…As we presented before, stress between the bonds resulting from the heterogeneous structure of the mineral (multiple ion substitutions at the same crystallographic site) may increase the solubility of apatite measured as the release of metal ions occupying the X site in the X 10 (YO 4 ) 6 Z 2 structure 17 , 41 . Therefore, we deduce that the nonuniformity of enamel caused by the incorporation of metals during orthodontic treatment might result in the release of calcium ions on a microscale.…”

“…The experiments were conducted for 18 months, during which a total of 360 rinsing cycles were performed. For technical breaks, the samples were placed in a laboratory refrigerator at temperature 4 °C (Whirlpool, Wrocław, Poland) in reactors filled with remineralizing solution to cover the tooth samples 17 , 29 . This lowered the kinetics of the de and remineralization reactions (Supplementary Fig.…”

“…Enamel-building minerals equilibrate with surrounding solutions via dissolution and recrystallization. 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 .…”

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.

Experimental data of thermodynamic state functions and molar volume for phosphate, arsenate, and vanadate apatites containing Ca, Sr, Ba, Pb, end Cd at the cationic positions Me2+ and F, OH, Cl, Br, and I at the halide position X were collected. The apatite supergroup splits into distinct subgroups (populations) constituted by Me10(AO4)6X2 with the same Me2+ cations and tetrahedral AO43− anions but with different anions at the X position. Linear relationships between various parameters within apatite subgroups are observed. The prediction method for standard enthalpies of apatites (ΔHºf,el) is based on regression analysis of the linear correlations within the subgroups between ΔH°f,el of apatites and their molar volume Vm, lattice energy UPOT, and ΔH°f,el of their anions AO43− or X−. This allowed to predict 22 new ΔH°f,el values for apatites and materials with an apatite structure. The prediction precision is comparable to the experimental uncertainty obtained when reproducing experimental data using calorimetric measurements or dissolution experiments and can be applied to a wider range of apatites than other methods.
