Abstract

Background and purpose: Reducing dental anxiety is a major aspect of childmanagement in dental visits. This crossover randomized clinical trial was designed to determine the effect of lavender aromatherapy on anxiety level during dental treatment and pain perception during dental injection in children.

Materials and methods: Twenty-four children aged 7-9 years received restorative treatment with lavender aromatherapy in the intervention session and without aroma in the control session. Salivary cortisol and pulse rate were measured to evaluate child's anxiety level and the Face Rating Scale (FRS) was used for assessing the pain perception during injection in both visits.

Results: The treatment effect on salivary cortisol, pulse rate, and FRS score was -8.01 ± 0.92 nmol/l, -11.17 ± 1.28 (in minutes), and -2.00 ± 0.41 respectively, which was statistically significant (P < 0.001).

Conclusion: Lavender aromatherapy can decrease dental anxiety and experienced pain in dental setting.
