| Outline of Final Research Achievements |
“Study 1”: 86 adult patients, who were scheduled to undergo impacted tooth extraction under intravenous sedation and local anesthesia, were divided into 4 groups due to the presence or absence of fear and music intervention. The effect of preoperative music intervention was evaluated by assessing the low-frequency/high frequency (LF/HF) ratio of heart rate variability (HRV), indicating sympathetic nervous activity (SNA), and a visual analog scale, indicating subjective preoperative anxiety. Music intervention is useful for relieving anxiety in patients with dental fear before entrance to a dental outpatient operating room.
“Study 2”: The study subjects were 22 healthy young volunteers. The effect of music intervention was evaluated by assessing the LF/HF ratio of HRV under position change or local anesthesia. In healthy young adults, SNA decreases significantly in the sitting and supine positions before local anesthesia with music sedation compared with nonmusic sedation.
