Indicators of jawbone microhardness in stress -induced experimental periodontitis

The article deals with the evaluation of microhardness of various parts of the jaw bone tissue at different stages of periodontitis in experimental animals under chronic stress. The study was carried out by using a stress-inducing device of our own design for 60 white laboratory rats. The duration of the experiment was 120 days. The results of the study showed that the microhardness of bone tissue depends on the intensity of the inflammatory process in periodontitis. The obtained data on the change in the microhardness of the bone tissue of the alveolar process in periodontitis will be useful in the calculation of loads on the teeth at dental implantation, prosthetics, the imposition of dental splints to fix jaw fractures and other forms of jaw pathology, accompanied by bone resorption.
