The aim of this study is to investigate the impact of lavender oil (Lavandula angustifolia) on anxiety, mood, vital signs (blood pressure, respiratory rate, heart rate and saturation) for oral surgery patients.
Lavender oil has sedative properties. Oral surgical procedures have been proven as to be the greatest concern among dental practices for patients. Limited randomized clinical trials have demonstrated evidence-based results of lavender oil, despite being the most effective essential oil for anxiety and stress. The hypothesis of the present study was that the inhalation of lavender oil prior to oral surgical procedures may reduce anxiety and consequently may effect intra and post-operative blood pressure, inspiration and heart rate.
