OBJECTIVES
To review the effect of lavender scent on anticipatory anxiety in dental participants.
METHODS
In a cluster randomized-controlled trial, patients' (N = 340) anxiety was assessed while waiting for a scheduled dental appointment, either under the odor of lavender or with no odor. Current anxiety, assessed by the brief State Trait Anxiety Indicator (STAI-6), and generalized dental anxiety, assessed by the Modified Dental Anxiety Scale (MDAS) were examined.
RESULTS
Analyses of variance (anovas) showed that although both groups showed similar, moderate levels of generalized dental anxiety (MDAS F((1,338)) = 2.17, P > 0.05) the lavender group reported significantly lower current anxiety (STAI: F((1,338)) = 74.69, P < 0.001) than the control group.
CONCLUSIONS
Although anxiety about future dental visits seems to be unaffected, lavender scent reduces state anxiety in dental patients.
目的
评估薰衣草气味对牙科患者预期性焦虑的影响。
方法
在一项整群随机对照试验中，在等待预约牙科就诊时，患者（N=340）的焦虑程度通过简短状态特质焦虑指标（STAI-6）进行评估，并根据改良牙科焦虑量表（MDAS）评估其一般性牙科焦虑程度。在薰衣草气味或无气味环境下进行评估。
结果
方差分析（ANOVA）显示，尽管两组患者的一般性牙科焦虑程度相似（MDAS F((1,338))=2.17，P>0.05），但薰衣草组的当前焦虑程度显著低于对照组（STAI：F((1,338))=74.69，P<0.001）。
结论
尽管对未来牙科就诊的焦虑似乎没有受到影响，但薰衣草气味可降低牙科患者的状态焦虑。
