THE OBJECTIVE
Of this work is to study the effectiveness of a method for determining the activity of a galvanic cell in the absence and presence of galvanic syndrome and diseases of the oral mucosa, the development of which may be associated with the irritating effect of direct electric current.
MATERIAL AND METHODS
Three groups of 50 patients were examined. All patients had at least 2 metal structures in the oral cavity. The first group consisted of patients without diseases of the oral mucosa and the absence of complaints specific to galvanic syndrome. The second group included patients without signs of pathological changes in the oral mucosa but with complaints are specific to galvanic syndrome. The third group consisted of patients with diseases of oral mucosa, the development of which could be due to the irritating effect of direct electric current. The electrochemical potential of each metal structure was determined and the difference between the potential obtained was calculated to detect metal structures that could form a galvanic pair. To determine the activity of a galvanic cell formed by galvanic vapors, the hydrogen index of the gingival fluid in the area of these structures was determined.
THE RESULTS OF THE STUDY
The difference in the electrochemical potentials of metal structures in the studied groups had no statistically significant differences (p>0.05) and amounted to: 129±24.7 mV in the first group, 138±35.3 mV in the second, 135±19.8 mV in the third. In the first group, 92% of patients had no significant difference in the hydrogen parameters of gingival fluid near pairs of metal structures (p>0.05). The hydrogen values were 6.6±0.26 at the cathode and 6.9±0.35 at the anode. In the second group, 88% of patients showed significant credible differences (p<0.05) in the hydrogen parameters of the gingival fluid near metal structures, at the cathode — 7.9±0.42, and at the anode — 6.3±0.31. In the third group, 86% of patients also showed a high difference in the hydrogen parameters of the gingival fluid near metal structures, at the cathode — 7.8±0.29, at the anode — 6.3±0.22 (p<0.05).
CONCLUSION
A method for detecting the activity of a galvanic element in the oral cavity, which consists in measuring the hydrogen parameters of the gingival fluid near metal structures forming a galvanic pair, allows you to objectively assess whether the galvanic element is in a passive or active state. In the absence of galvanic syndrome and diseases of the oral mucosa, the detection rate of active galvanic cells was only 8%, wwhile in the presence of galvanic syndrome it was 88%, and in diseases of the oral mucosa it was 86%.
