The authors studied the use of vibroacoustic oscillations to increase the efficacy of complex therapy of periodontitis. The subjects of the study were 150 patients suffering from mild, moderate, or severe periodontitis. The results of the treatment were controlled using such clinicofunctional methods and indices as Schiller-Pisarev test, periodontal index, hygiene index, thermometry, rheoparodontography, and laser Doppler flowmetry. In treatment, "Vitaphon " device was used as the source of vibroacoustic oscillations. The authors developed the therapeutic technique and indications to treatment, and performed analysis of the therapeutic action of different vibroacoustic regimes. Considering the dynamics of patients' complaints and the results of clinicofunctional examinations, the study demonstrates therapeutic effects of vibroacoustic oscillations, such as periodontal blood flow acceleration, which, in turn, diminishes stagnation and improves trophic processes.
