Abstract

Introduction: Anxiety is one of the components of patient stress in the dental office and is recognized as one of the main factors that negatively affect treatment. The control of anxiety can be performed through conscious sedation, for which benzodiazepine is the drug of choice in dental practice, however present side-effects.

Objective: The objective of the following study is to evaluate the efficacy of Valeriana officinalis L. (Valerian) for control of anxiety during the third molar surgery.

Materials and methods: A single oral dose of either Valerian (100 mg) or placebo was randomly administered 1 h before each surgical procedure to 20 volunteers between 17 and 31 years of age. Anxiety level was assessed by physiological parameters (blood pressure and heart rate [HR]) and the observation of signs. Descriptive analysis, Chi-square test, Friedman test, Wilcoxon test and effect size test were performed (P < 0.05).

Results: According to the researcher's (80%) and surgeon's (75%) evaluations, the patients treated with Valerian were calmer and more relaxed during surgery. Valerian had a greater effect on the maintenance of systolic blood pressure and HR after surgery.

Conclusion: Valerian was more effective at controlling anxiety than a placebo when used for the conscious sedation of adult patients submitted to impacted lower third molar surgery.

Keywords: Anxiety; oral surgery; phytotherapy.
