Summary
Introduction: This prospective study aimed to assess the impact of olfaction on providing
positive emotional responses and reducing dental anxiety and pain.
Material: A randomized double-blinded controlled study was enrolled on female patients. The
olfaction was stimulated via lavender essential oils. Patients were divided into lavender and
control groups. Patients in lavender group inhaled 2 % lavender vapors. In control group,
patients inhaled distal water vapors. The variables included pain, anxiety, and vital signs.
Anxiety was measured through Modified Dental Anxiety Scale (MDAS) and Speilberger State-Trait
Anxiety Inventory (STAI) questionnaires. Pain was evaluated through visual analog scales
(VAS). Vital signs included the systolic (SBP) and diastolic blood pressure (DBP), heart rate
(HR), respiratory rate (RR), and oxygen saturation (Spo2). All variables were assessed before
the intervention, 20 minutes after inhalation of vapors, and at the end of dental settings.
The last evaluation was on the day after visits. P-values < 0.05 were considered significant.
