Management of dental anxiety is one of the most challenging tasks for pediatric dental practitioners. Conscious sedation or general anesthesia had been used to solve the problem. Because of the risks of these methods, aromatherapy makes a big leap in addressing dental anxiety. Aim: Evaluate and compare the effect of essential oils (lavender and orange) inhalation on children's vital signs and anxiety during dental procedures. Materials and Methods: The study was conducted on 60 children aged 6 to 12 years who need to extract at least one primary tooth. The children were divided into three groups according to the type of inhaled oil; Group (A): Lavender essential oil, Group (B): Orange essential oil, Group (C): Control group. All vital signs including pulse, blood pressure and oxygen saturation were measured before starting the treatment and after the inhalation of the essential oil and then after the anesthesia and extraction. Wrong backer scale was used to evaluate children's anxiety level. Results: Compared with controls, both the Lavender group and the Orange group showed a significant change in post-treatment anxiety levels with respect to Wong Packer Pain Scale, along with a decrease in pulse rate and respiratory rate. When compared with Lavender, Orange oil did not result in statistical significance, although Lavender showed better results than Orange. Conclusion: Both Lavender and Orange essential oil are effective in managing anxiety and can be used to prepare the anxious child before dental procedure.
