Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The patients will be divided into a control group in which the patients will be subjected to vapors of plain distal water, and lavender group where the patients will inhale vapors of the lavender oil to stimulate olfaction

Primary Study Purpose

PREVENTION

Blinding Strategy

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors

The randomization will be performed according to patients' sequences where all odd numbers of patients will be incorporated into control group, while even numbers will be included in lavender group. The patients will not be informed about the type of the essential oil. T This was achieved by inserting lavender vaporizers in all setting rooms and clinics. So that the patients will believe that there is no extraordinary maneuver in the clinics. Also, all the dentists who treated the patients and evaluators who will interview the patients and questionnaires, will not be informed of the type of the essential oil which will be used. The statistician who will analyze the questionnaires will be informed that the study's groups are named as group A or B.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lavender group

On the day of the lavender group, after filling the first phase questionnaire, 20 drops of the lavender oil will be added to the electrical aromatherapy vaporizer near the patient's chair at a distance of 20 cm in the waiting room. After 20 minutes, the second phase questionnaire will be given to the patient, and then the patient will be transformed to dental clinics in which the lavender vaporizer will be placed near the dental unit at a distance of 20 cm. The vaporizer will be also prepared by adding 20 drops of the lavender which will be added added every 20 minutes until the dental sitting will be finalized, and the third questionnaire will be answered. At home, the patients will be asked to pour 3 drops of the lavender on a pad and inhale it for 5 minutes from 10 cm distance every one hour until they attend on the next day to answer the fourth questionnaire.
