The study of the electrochemical potentials of metal structures in the oral cavity in diseases of the oral mucosa

The aim of the study was to research the electrochemical potentials in the oral cavity in various oral mucosa diseases.
On the Department of Therapeutic Dentistry in I.M. Sechenov First Moscow State Medical university was examined 342 patients, aged from 36 to 78 years old with suspected development of galvanic syndrome in oral cavity. Women accounted for 61% (207 people), men - 39% (135 people). 138 patients were referred to us with a diagnosis of glossalgia and burning mouth syndrome, 54 patients with limited hyperkeratosis of the oral mucosa, 45 patients with a diagnosis of verrucous leukoplakia, 63 patients with a diagnosis of lichen planus (erosive and ulcerative form) and 42 patients with erythema migrans. All patients aimed at studying the electrochemical potential had various prosthetic metal constructions in oral cavity: crowns, bugel denture, implants, inlays, metal pins. As a measuring device, when determining the electrochemical potentials of the oral cavity, a millivoltmeter with high input resistance (more than 20 mega ohm),
sensitivity above 200 mV, protection from external interference and autonomous power supply was used.
As a result of the study, it was established that the determination of the electrochemical potentials of metal structures located in the oral cavity allows confirming or refuting the presence of galvanic syndrome in various oral mucosa diseases. In patients diagnosed with glossalgia, burning mouth syndrom and erythema migrans, a high difference in the electrochemical potentials of various metal structures was observed in only 50% of the patients examined. In erosive and ulcerative lichen planus, verrucous leukoplakia and limited mucosal hypekeratosis, the number of patients who had confirmed galvanic syndrome, was above 70%.
