Stress assessment by dental treatment - Stress assessment by dental treatment

This study examined whether green color exposure reduced stress, anxiety, and pain during peripheral intravenous cannulation (PIC). The outcome measures were salivary alpha-amylase (sAA) activity and stress-related hemodynamic changes, and the visual analog scale anxiety (VAS-A) and pain (VAS-P). The sAA in the clear group significantly increased during PIC compared with baseline, but did not increase in the green group. Median VAS-P during PIC were lower in the green than in the clear.
