A contribution to the Examination of Oral mucosa membrane bioimpedance.

Asample of 19 healthy persons were tested by means of a specially adapted measuring device in order to obtain module values and bioimpedance phase angles in ten reference points distributed along the oral mucosa. The measurements were carried out at ten approximately logarithmic frequencies set out within the range of 30 Hz to 1 MHz. Each measurement lasted 30 seconds. The results showed significant similarities on the group distribution of measuring points. This lead to the conclusion that the relevant measuring points were at lingual dorsum mucosa, hard palate and buccal mucosa, whereas the values for other less accessible regions did not significantly differ from the former. It was also found that the measuring results were concentrated at low and high frequencies. Therefore, it is advisable to narrow down the measuring range to 103 - 105 Hz.
