Heart Rate Variability, Pain Syndrome and Cortisol Concentration in Oral Fluid During Sinus-Lifting And Dental Implantation

Acute pain serves as an important biological function because it warns of the degree of damage or its potential deterioration. This is a rapid response to a harmful stimulus that does not lead to long-term consequences [1]. On the other hand, it can have various psychological and emotional consequences. Attention is therefore focused on aggressive prevention and treatment of acute pain to reduce complications and progression of chronic pain conditions. The study of pain syndrome after dental surgery is still relevant [2, 3], since in clinical [2-11] and experimental studies [12-20] it was shown that surgical interventions in the maxillofacial region entail a cascade of stress reactions [21, 22].
