Influence of coherent light on blood microcirculation in human oral cavity mucous membrane: An objective monitoring by laser photoplethysmography and Doppler flowmetry

摘要

Integrated device for laser therapy and monitoring of blood microcirculation has been developed. Influence of laser irradiation on the statement of blood microcirculation in mucous membrane of human oral cavity has been investigated. Changes of blood saturation and velocity of blood microcirculation have been studied by methods of laser photoplethysmography and Doppler diagnostics. Influence of coherent light on the intensity of microcirculation in the capillary net of mucous membrane has been demonstrated directly during the short-time session of laser therapy.
