Sažetak
Introduction- Bioimpedance (BI)-based diagnostic methods of the oral mucosa are becoming increasingly important due to their non- invasiveness, low costs and immediate results. Different devices and forms of terminal electrodes used in research are placed on the mucosa by the researcher's hand, and thus, can lead to inconsistent results due to hand movements. Aim - To investigate the effect of fixed pressure value, as a method for the attachment of electrodes, on the results of oral mucosa BI measurements.Material and methods - The study included 101 participants with healthy oral mucosa. BI was measured at 14 measurement points. The measurements were performed with an original measurement device comprising of an intraoral sensor, measuring instrument and a PC. During measurements the intraoral sensor was placed on the mucosa, and when the required subpressure was obtained, the system registered a measurement. The subpressures of 250 and 350 mB were used for the fixation of electrodes.Results - Values of BI measured at higher subpressure were significantly lower at all frequencies and locations, except on the dorsum of the tongue, lateral tongue and sublingual mucosa. On these locations, the mucosa exerted lower resistance to subpressure allowing better adherence of the electrodes and less . Conclusion- BI values can vary depending on the pressure exerted by measuring electrodes on the mucosa. Therefore, the design of a future measuring device should take into account the standardization of electrode pressure on the mucosa in order to avoid measurement errors due to pressure inconsistencies.
