Influence of ultrasonic broadband split signal on the morphological state of hard tissues of teeth and bone tissue of jaws during shadow velosymmetry

OBJECTIVE: Conducting a preclinical study of the effect of an ultrasound broadband complex-modulated "split" signal on the hard tissues of teeth and jaw bone of experimental animals. MATERIAL AND METHODS: =30. The exposure time was recorded in the "Pro-VUD" program. RESULTS: The average ultrasonic wave velocity (UWV) through the central incisors on the upper jaw on the right (1692±27 m/s) and left (1744±24 m/s) was 28.2 and 29% lower than the UWV through the central incisors on the corresponding sides of the lower jaw (2353±43 m/s on the right and 2459±34 m/s on the left). Microcomputer tomography of the studied tissue samples in the control group did not reveal the formation of pathological foci, which are characterized by a decrease in tissue density. Comparative histological analysis of the teeth of rabbits in the control and experimental groups did not reveal any pathomorphological changes. CONCLUSION: s.
