В качестве измерительного устройства для определения электрохимических потенциалов полости рта использовали милливольтметр постоянного тока с высоким входным сопротивлением (более 20 МОм), чувствительностью выше 200 мВ и защитой от воздействия внешних помех и автономным электропитанием. В результате проведенного исследования установлено: определение электрохимических потенциалов металлических конструкций, расположенных в полости рта, позволяет подтвердить или опровергнуть наличие гальванического синдрома при различных заболеваниях слизистой оболочки. При глоссалгии, стомалгии и десквамативном глоссите высокая разница электрохимических потенциалов металлических конструкций наблюдалась лишь у 50 пациентов, а при эрозивноязвенной форме красного плоского лишая, ограниченном гиперкератозе слизистой оболочки и верукозной форме лейкоплакии, число пациентов, у которых было подтверждено наличие гальванического синдрома, было выше 70. ABSTRACT 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 M), 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 erosiveulcerative 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. |
