Screening assessment for the presence of inflammatory processes, including those during prosthetics, allows to reduce the number of postoperative complications. In this regard, the development of new screening methods is an urgent task, since the existing traditional laboratory methods (cytology, bacterial analysis) do not meet modern requirements due to their invasiveness, duration of implementation and the need for specialized equipment. The paper presents a technique for screening assessment of electrochemical parameters of saliva obtained using a non-invasive express method – joulemetry.

Purpose – development of a technique for screening assessment of the state of the oral mucosa based on joulemetric analysis of electrochemical parameters of saliva and its software implementation.

A technique for screening assessment of the state of the oral mucosa and its software implementation have been developed using wavelet filtering (sym7), approximation of the obtained experimental data by a 5th degree polynomial and calculation of the electrochemical parameter "current work" (Q) at fixed time intervals. The method is implemented as a hardware and software complex. As a result of the experimental studies conducted using the complex, a statistically significant 2-fold increase in the average Q value was revealed in inflammatory pathologies of the oral mucosa compared to the comparison group (0.130±0.050 mJ versus 0.065±0.012 mJ; p<0.001).

The developed method and its software implementation allow for the study to be conducted in 5-7 minutes, and based on the study results, a conclusion can be made about the presence or absence of an inflammatory process in the oral cavity, which allows for a decision on the possibility of prosthetics.
