Way to restore blood flow in the microvasculature VASCULAR DENTAL PULP the prepared by the action of an alternating magnetic field

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to dentistry. Method includes carrying out examination by means of photoplethysmography (PPG) and further impact with alternating magnetic field. In carrying out PPG sensor of photoplethysmographer is fixed on movable guide, fixed on headband, and is centred onto area of pool of vessels of prepared teeth zone, from external side of lips and cheeks. After that, recording of parameters of local peripheral vessels of microcirculatory bed is performed in graphic and digital form for 15-20 seconds with patient in immobile free position. Recording is performed in form of histogram of PPG frequency spectrum in range 10-30 Hz. Performed are recording of PPG graph, which shows volume blood flow, recording of differential PPG, showing dynamics of blood flow rate, and recording of graph of differential PPG differential, showing dynamics of its acceleration. Then, value of dominating frequency is selected from frequencies of PPG spectrum. Selected frequency value is given to generator of current of sinusoidal form of device for control of tone of microcirculatory bed vessels. Electromagnetic emitter is fixed on mobile guide of headband and is installed in area of prepared teeth, from external side of cheeks or lips, at the distance not larger than 1 cm from their surface. Session of magnetic therapy is performed with selected frequency value from 5 to 40 Hz, intensity 15-60 mT for 20 minutes. Total time of impact does not exceed 35 minutes.;EFFECT: method reduces terms of recovery of blood flow in pulp vessels due to impact with alternating magnetic field at frequency of spontaneous oscillations of local vessels.;3 cl, 1 ex
