Annotation: Biological fluid is a complex tool that reflects the dynamic stability of the internal environment of the body, however, oral fluid can have different, physicochemical and biological properties under the influence of various factors and is one of the indicators of the body's reactivity . Numerous scientific findings have led us to conclude that human biological fluid (saliva) is a unique substance with great potential for use in basic research and medical diagnostics. Depending on the internal structure of biological fluids and their quantities, the physical changes in the evaporation process and the methods of solid phase assessment are widely used in laboratory diagnostics, the simplicity of the process of obtaining biological fluids, as well as high sensitivity and access to information is one of the new directions that has begun to be explored. Typically, when using this method, the morphology of the physical processes that take place during the evaporation of a certain amount of the biological fluid under study, which takes the form of droplets, and the solid sediment (facies) formed after evaporation. is studied. To study the process, we used a modern microscope that can meet the requirements of the time, the main function of the microscope is not only to show the object in an enlarged view, but also to take pictures, transfer the captured object to the screen, determine their pointers , creating a video image. In the process of obtaining the results of the experiment, we will be able to measure values on a small scale, ie at the micrometer level.
