Non-randomized controlled prospective study on perioperative levels of stress and dysautonomia during dental implant surgery

This is the authors' abstract. We don't add key points for this paper.

CgA levels were high in both groups immediately before surgery, and thus CgA values immediately before surgery may not be a reliable indicator of the need for intravenous sedation. Also, spectral analysis of HRV, especially ΔL/H and ΔCCV(HF), could be useful for assessing tension and anxiety.
