Effectiveness of Auditory Distraction and Brief Relaxation Therapy in Reducing Anxiety in Dental Patients Undergoing Extraction: A Randomized Controlled Trial

Featured Application Anxious dental patients are arduous to treat, need more time, and have behavioral issues which lead to a stressful and unpleasant experience for them and the treatment provider. Dentists must take additional measures to make the overall clinical experience more pleasant for their patients. The application of these unintrusive interventions, i.e., auditory distraction and brief relaxation therapy, before a dental treatment is thus encouraged. Objective: This study compared the effectiveness of auditory distraction and brief relaxation therapy for reducing anxiety in patients undergoing tooth extraction. Methods: A non-blind, three-armed, randomized control trial was carried out. The targeted study population were patients who needed extraction of a non-restorable and non-mobile molar tooth. Eighty-six patients were recruited; the brief relaxation therapy and auditory distraction groups had 32 participants each, while 10 of the 22 participants in the control group were excluded due to missing data. The Hierarchical Anxiety Questionnaire was used to assess the anxiety level. The Mann-Whitney U or Kruskal-Wallis test was performed to compare means between the groups. The before and after comparisons in each group were carried out using the Wilcoxon Signed-Rank test. The alpha value was set at 0.05, and data were analyzed using SPSS version 24. Results: The mean anxiety score after brief relaxation therapy and auditory distraction had significantly decreased (p < 0.001). Although not significant (p = 0.13), there was a slight increase in the anxiety score of the study participants in the control group just before the extraction procedure. Brief relaxation therapy was significantly effective in reducing anxiety scores in comparison to the control group (MD = 5.87, 95% CI = 2.58, 9.17; p = 0.001), but auditory distraction was not (p = 0.14). Conclusion: Both auditory distraction and brief relaxation therapy were effective in reducing patient anxiety before a dental procedure. Furthermore, it would be interesting to learn if these findings remain consistent for more complex dental procedures, such as surgical removal of an impacted third molar.
