Abstract

Brainwave entrainment comprises binaural beats with a visual stimulus having a slight difference in their frequencies. When presented to a listener, they have psychophysiological effects corresponding to the frequency difference. One such effect is the relaxation achieved within the alpha range (8−13 Hz). Hence, the aim of the study is to evaluate the effectiveness of brainwave entrainment in fear and anxiety in pediatric patients undergoing dental treatment. Pediatric patients (252) aged from 7 to 12 years requiring dental treatment were presented with brainwave entrainment (experimental) delivered using a “David delight plus device” and standard behavior management protocol was delivered (control) for 10 min. Baseline and post-assessment of anxiety and fear levels were done using the Visual Facial Anxiety Scale (VFAS) and Frankl’s behavior rating scale with Wright’s modification (FBRS). Vitals such as blood pressure and pulse rate were also measured. The study sample (n = 252) comprised 118 females and 134 males. The non-significant differences for values of (VFAS1, FRS1, HR1, and BP1) indicated similar baseline characteristics. In the brainwave entrainment group, the p values of the Mann-Whitney U test and Wilcoxon Signed Ranks Test (P < 0.01) between the two-time points, indicated a statistical difference for the values of (VFAS1, FBRS1, HR1, BP1) and (VFAS2, FBRS2, HR2, BP2). Therefore, brainwave entrainment is effective in reducing pre-operative dental anxiety in pediatric patients undergoing dental treatment. Therefore, they can be used as a non-pharmacological and non-invasive behavior management aid. Keywords: Brainwave entrainment, AV entrainment, Binaural beats, Alpha waves, Behavior management
