The use of photoplethysmography allows an accurate assessment of the level of blood supply in inflammatory symptoms in patients with diabetes after tooth extraction, this method has the positive properties of non-invasiveness, high sensitivity and probabilistic ease of examination. Photon radiation has been shown to increase blood vessel wall elasticity, erythrocyte elasticity, blood oxygen transport function, cell membrane activity, accelerate tissue regeneration, reduce lipid oxidation, and normalize blood rheology. The photon radiation of the "MultiSpectr-001" multispectral physiotherapy device has been shown to lead to anti-inflammatory, desensitizing, analgesic, antispasmodic, anti-edema effects, which was confirmed in this study in the treatment of diabetic patients.
