Relevance: the purpose of this work was to study the effectiveness of proposed treatment and rehabilitation complex for patients with generalized chronic periodontitis and bruxism.

Materials and methods: we examined 73 patients aged 30 to 45 years diagnosed with generalized chronic periodontitis of moderate severity and bruxism. Control group included 15 healthy individuals of the same age for clarify normal functional parameters. Clinical, Doppler flowmetry and electromyographic methods were used for evaluation of the effectiveness of proposed treatment and rehabilitation complex.

Results: the course of treatment resulted in the increase in blood flow perfusion volume by 37.7% (p < 0.05), of blood flow perfusion rate by 58.2% (p<0.05) from baseline values. At the same time, the decrease in bioelectric activity of temporal muscle at rest by 51.82% (p >< 0.05), at voluntary contraction – by 40.4% (p<0.05), the decrease in bioelectric activity of masseter muscle at rest – by 47.4% (p><0.05), at voluntary contraction - by 35.12% (p >< 0.05) from values before treatment, were observed.

Conclusion: data obtained on the basis of electromyography and laser Doppler flowmetry showed that developed treatment and rehabilitation complex is an effective method for correcting the microcirculation in periodontal vessels and the functional activity of the muscles of maxillofacial area.
