The effects of lavender scent on dental patient anxiety levels: a cluster randomised-controlled trial.

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.
