Abstract
Introduction: The aim of the present study was to evaluate the effectiveness of cannabidiol-rich Cannabis extract in reducing anxiety and postoperative pain in patients submitted to endodontic treatment METHODS: The study was carried out after approval by the Research Ethics Committee (Registration No. 5.075.961). The following groups were tested: cannabidiol (CBD) and placebo. Pain was measured using a Visual Analog Scale (VAS) before the start of treatment and 24, 48 and 72 h and 7 days after the session. Anxiety was assessed using the Modified Dental Anxiety Scale and a VAS, before and immediately after treatment. In addition, salivary cortisol was measured before drug administration and after anesthesia. Data were analyzed descriptively using absolute frequencies and percentages, with a 5% margin of error.
Results: The mean anxiety scores were higher in the Cannabidiol group than in the placebo group in each assessment (pre: 5.06 versus 3.07, respectively; post: 4.61 versus 2.60). However, there was no significant difference in the reduction of dental anxiety at the beginning of the consultation and throughout the procedure. We did not find statistically significant differences in postoperative pain between the Cannabidiol and placebo groups at any of the time points.
Conclusion: There was no evidence of an exposure-response relationship between the intervention and control groups. However, more studies are needed to determine clinical outcomes.
期刊介绍:
The Journal of Endodontics, the official journal of the American Association of Endodontists, publishes scientific articles, case reports and comparison studies evaluating materials and methods of pulp conservation and endodontic treatment. Endodontists and general dentists can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation in the one journal that helps them keep pace with rapid changes in this field.
