Aim. To assess the influence of low frequency magnetic fields on the contents of calcium, magnesium and fluoride in saliva. Subjects and methods. Sixty two patients were subjected to magnetic stimulation with low frequency magnetic fields of mean induction 3 μT at the first intervention and 4 μT at the following fourteen ones. Saliva was sampled before magnetic stimulation and after the 5 th, 10 th and 15 th interventions. The contents of calcium and magnesium ions were measured by means of atomic absorption spectrometry. The content of fluoride was determined using an ion-selective electrode. Results. No statistically significant differences were found between the calcium concentrations before magnetic stimulation and after 5, 10 and 15 interventions. Statistically significant differences in the magnesium concentrations were observed only between 10 th and 15 th interventions. No statistically significant differences in fluoride concentrations were found. Conclusion. Low frequency magnetic fields have no or weak influences on the content of calcium, magnesium and fluoride in saliva.
