DEVELOPMENT OF THE HARDWARE AND SOFTWARE COMPLEX FOR NON-INVASIVE EXPRESS DIAGNOSTICS OF THE STATES OF PERIODONTAL TISSUES IN THE POST-OPERATIVE PERIOD
Abstract
Background. The aim of the work is to develop a method for assessing the state of periodontal tissues and a hardware-software complex that implements this method. Materials and methods. The possibility of using electrochemical methods for assessing the state of periodontal tissues is substantiated. The structure of the hardware-software complex based on the joulmetric assessment of the electrochemical parameters of a biological object is considered. The advantages and disadvantages of electrochemical two-electrode sensors are analyzed in detail. The analysis of materials for electrode insulation was carried out. An algorithm for processing the received data is described. An experimental study of the state of periodontal tissues was carried out using the developed system. The pilot study involved 60 people aged 19 to 45 years. The study group included people with inflammatory diseases of periodontal tissues (n = 30), the control group consisted of people with a healthy oral cavity (n = 30). Results. In the course of the experimental studies of the electrochemical properties of periodontal tissues by joulemetry using the developed hardware and software complex, it was found that in patients with a healthy oral cavity, the current work values range from 0.046 to 0.137 μJ and average 0.088 μJ. The current work values in patients with severe clinical manifestations of periodontitis range from 0.157 to 0.351 μJ and average 0.248 μJ. Conclusions. Thus, the relationship between the electrochemical parameter of the current work and the activity of inflammation in periodontal tissues was obtained, which is characterized by the fact that with an active inflammatory process, the values of this parameter are higher compared to the state of the object in the norm.
