The determination of electrochemical potentials in the oral cavity, as a way to diagnose galvanic syndrome, which contributes to the development of diseases of the mucous membrane
The aim was to study the electrochemical potentials in the oral cavity with various diseases of the mucous membrane. Materials and methods: on the basis of the Department of Therapeutic Dentistry of the First Moscow State Medical University by Sechenov examined 114 patients aged 36 to 78 years with suspected development of galvanic syndrome of the oral cavity. Women accounted for 61% (69 people), men - 39% (45 people). 46 patients were diagnosed with glossalgia and stomatalgia, 18 patients with limited oral hyperkeratosis, 15 patients with the diagnosis of leukoplakia, 21 patients were diagnosed with lichen planus (erosive and ulcerative form), and 14 patients were diagnosed with desquamative glossitis. In all patients aimed at investigating the electrochemical potential, the mouth had various orthopedic structures of metals: crowns, clasp prostheses, implants, tabs, metal pins. As a measuring device, in determining the electrochemical potentials of the oral cavity, a DC millivoltmeter with a high input resistance (more than 20 MQ), sensitivity above 200 mV, protection from external interference and autonomous power supply was used. As a result of the conducted research it was established: 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 diseases of the mucous membrane. According to our study, with glossalgia and stomalgia, a high difference in the electrochemical potentials of various metal structures was observed in only 50% of patients, then in the erosive-ulcerative form of red flat lichen and the veracious form of leukoplakia, the number of patients who confirmed the presence of galvanic currents in the oral cavity, was above 70%.The data obtained indicate that the galvanic syndrome is a factor contributing to the development of different diseases of the oral mucosa.
