Sažetak
Aim was to determine effect of pH, fluoride (F−) and hydrofluoric acid concentration (HF) on dynamic of nickel (Ni2+) and titanium (Ti4+) ions release. Nickel-titanium wires with untreated surface (NiTi), rhodium (RhNiTi) and nitride (NNiTi) coating were immersed once a week for five min in remineralizing agents, followed by immersion to artificial saliva. Ion release was recorded after 3, 7, 14, 21 and 28 days. Pearson correlations and linear regression were used for statistical analysis. Release of Ni2+ from NiTi and NNiTi wires correlated highly linearly positively with HF (r=0.948 and 0.940, respectively) ; for RhNiTi the correlation was lower and negative (r=−0.605 ; p<0.05). The prediction of Ti4+ release was significant for NiTi (r=0.797) and NNiTi (r=0.788 ; p<0.05) wire. Association with F− was lower ; for pH it was not significant. HF predicts the release of ions from the NiTi wires better than the pH and F− of the prophylactic agents.
