Can Binaural Beat Music Be Useful as a Method to Reduce Dental Patients' Anxiety?

BACKGROUND: One of the main issues in dentistry and a barrier to offering dental treatment is anxiety. The usage of music is one of the nonmedical ways to reduce anxiety. Binaural beat technology is used as a music treatment technique. The goal of this study wasto determine whether employing binaural beat technology during and after dental appointments can help patients feel less anxiety and pain. METHODS: In this clinical trial, 80 patients who were candidates for mandibular wisdom tooth surgery (in 2 test and control groups) were examined. In the control group, after the injection of anaesthesia and before surgery, they waited for 10 minutes and during this time no intervention was done. In the test group, thought, after the injection of anaesthesia, the patients were asked to listen to binaural beat music with headphones for 10 minutes. The level of anxiety of the patients before and after the intervention was checked with the Spielberger State-Trait Anxiety Inventory and finally the data were entered into SPSS version 21 software. RESULTS: The score of overt anxiety (P = .524) and covert anxiety (P = .118) before the start of the study was not significant between the 2 groups, but overt anxiety (P = .001) and covert anxiety (P = .000) after the intervention in the test group decreased significantly. CONCLUSIONS: The research showed that the use of binaural beat music has significantly reduced the level of overt and covert anxiety in patients and can be used as an alternative nonpharmacologic method to reduce anxiety.

Antifungal Properties of Zataria multiflora on Candida species: A Systematic Review.

BACKGROUND AND PURPOSE: Candida infections have increased significantly in the antimicrobial resistance era, and synthetic antifungal drugs have limitations. The present work aimed to review the antifungal properties of Zataria multiflora (Z. multiflora) as an herbal remedy. METHOD: PubMed, Scopus, ScienceDirect, Web of Science, SID, Civilica, and Magiran databases were searched for the antifungal activity on in vitro, in vivo, dental biofilm, and clinical studies of Z. multiflora on Candida species. RESULTS: Overall, 33 articles evaluated the effect of Z. multiflora on Candida species and classified them into four groups, as follows in vitro (23), dental biofilm (6), in vivo (2), and clinical studies (3). All studies considered Z. multiflora effective in reducing or even inhibiting the growth of Candida species. NoMFC significant differences were seen in the effect of Z. multiflora on susceptible Candida compared to the resistant groups of Candida in the studies. It was also influential in inhibiting C. parapsilosis, C. glabrata, C. krusei, C. kefyer, and C. zeylanoides. CONCLUSION: Considering the side effects and resistance of current antifungal drugs as well as the benefits of using herbal medicines, such as lower cost, less likely to develop drug resistance, the absence of side effects, and toxicity compared with chemical ones, it is possible as a powerful alternative to replace or combine with the current antifungal for Candida infection therapy along with other therapies.
