The effect of alpha binaural beat music on orthodontic pain after initial archwire placement: A randomized controlled trial.

OBJECTIVE: The objective of this article was to evaluate the effect of alpha binaural beat music on pain level after initial placement of a maxillary fixed appliance, compared to music without binaural beats (placebo) and no music (control). METHODS: 60 patients undergoing maxillary fixed orthodontic appliance and initial archwire placement were randomly allocated into the three aforementioned groups. The pain level experienced was monitored for the following seven days, using the short-form McGill pain questionnaire (SF-MPQ). RESULTS / DESCRIPTORS: Intensity of both sensory and psychological aspects of pain reduced significantly in the binaural beat music (BBM) group, compared to the control, after the 5th day. Statistically significant lower affective and total pain scores were also found on day 6 for the placebo group, compared to the control. Present Pain Intensity (PPI): Statistically significant lower scores were found between the BBM group and the control group from days 3 to 7. Statistically significant lower scores were also found between the placebo and the control groups on days 4, 5 and 6. Visual Analog Scale (VAS): Compared to the control group, the placebo group had a lower VAS score on day 4, and the BBM group had lower scores on days 6 and 7. CONCLUSIONS: There was a significant reduction of pain demonstrated in the BBM group, compared to the control, toward the end of the first week of treatment. There was no difference in reported pain between the BBM and placebo groups for any of the scores.

RESUMO Objetivo: O objetivo deste artigo foi avaliar o efeito da música alfa com ritmo binaural sobre o nível de dor após a instalação de um aparelho fixo superior com arco inicial, em comparação com a música sem ritmos binaurais (placebo) e sem música (controle). Métodos: 60 pacientes submetidos a instalação de aparelho ortodôntico fixo superior e do arco inicial foram alocados aleatoriamente nos três grupos acima mencionados. O nível de dor experimentado foi monitorado durante os sete dias seguintes, usando a forma curta do questionário de dor McGill (SF-MPQ). Resultados: Após o quinto dia, a intensidade dos aspectos sensoriais e psicológicos da dor foi significativamente reduzida no grupo de música com ritmo binaural (BBM), em comparação com o grupo controle. Escores significativamente menores de dor afetiva e total também foram encontrados no dia 6 para o grupo placebo, comparado ao controle. Intensidade da Dor Presente (PPI): escores significativamente menores foram encontrados para o grupo BBM, em comparação ao grupo controle, nos dias 3 a 7. Escores significativamente menores também foram encontrados para o grupo placebo, em comparação ao grupo controle, nos dias 4, 5 e 6. Escala Visual Analógica (VAS): comparado ao grupo controle, o grupo placebo teve um escore VAS menor no dia 4, e o grupo BBM teve escores menores nos dias 6 e 7. Conclusões: No final da primeira semana de tratamento, houve redução significativa da dor no grupo BBM, em comparação ao grupo controle. Não houve diferença entre a dor relatada nos grupos BBM e placebo para qualquer um dos escores.
