Assessing the Efficacy of Lemongrass and Lavender Aromatherapy in Reducing Dental Anxiety and Pain Associated With Local Anesthetic Injections in Pediatric Dental Patients

The goal of this clinical trial is to evaluate whether aromatherapy using lemongrass or lavender essential oils can reduce dental anxiety and pain perception in children aged 7-11 years undergoing local anesthetic administration in a pediatric dental setting. The main questions it aims to answer are: Does lemongrass or lavender aromatherapy reduce anxiety levels, as measured by salivary cortisol, in children receiving local anesthesia? Does aromatherapy influence pain perception and physiological stress (heart rate) during the procedure? Researchers will compare a lavender aromatherapy group, a lemongrass aromatherapy group, and a control group without aromatherapy to see if the essential oils have a calming effect that reduces anxiety and pain compared to no intervention. Participants will: Inhale either lavender, lemongrass, or no essential oil (control) for two minutes via nebulizer. Undergo local anesthesia administration for a dental procedure. Provide unstimulated and stimulated saliva samples before and after the procedure for cortisol analysis. Report their pain level using the Wong-Baker Faces Pain Rating Scale. Have their heart rate measured before and after the procedure using a finger-type pulse oximeter.
