A RCT study of relieving effect of music sedation on psychological stress before entering dental outpatient operating room -Investigation with heart rate variability analysis- - A RCT study of relieving effect of music sedation on psychological stress before entering dental outpatient operating room

Among patients in the dental anxiety block, LF/HF and VAS were significantly decreased in the music group after listening to music compared to the non-music group (Mann-Whitney U test P<0.05, respectively), while there were no significant changes in HF, CVRR and heart rate between the two groups. Among patients without dental anxiety, no significant differences were seen between music and non-music groups.
