Sažetak
The aim of this study was to measure the magnetic field in dentistry together with simultaneous substraction of direct ground component of the magnetic field. The research instrument used to measure the power of the magnetic field was of our own design. It measures the
magnetic field by the Hall sensor that is powered with 5 to 10 V and is integrated in one chip together with preamplifier. The sensor output is differential (Q1-Q2) and proportionate to measurement values of magnetic induction. As the values of alternate fields in a laboratory setting are small the differential output voltage should be
increased by about 100 times. Our study samples consisted of instruments currently available in dentistry: halogen lamps, polymerizing lamps, amalgam mixers, micromotors and dental chairs. On the basis of our study results and statistical analysis the following conclusions are made magnetic field spreads through space in ISOTROPIC manner. The greatest frequency obtained at the smallest distance was 100 kHz. The sensitivity of the measurement
instrument was 0.0001 μT and the majority of instruments produce magnetic radiation higher than 4o G. The power of the magnetic field decreases with increasing distance from the source. The investigated instruments produce a relatively mild magnetic field. The instruments with stronger magnetic fields are located far enough from the persons on whom they act. The newly produced instrument acts on their environment by smaller magnetic fields.
