Adjunct music therapy and haemodynamic balance in mandibular third molar surgery: A randomized clinical study

Abstract

Introduction: There are conflicting evidences that music can improve psychoemotional stability and haemodynamic changes during surgeries, as well as improve doctor-patient relationship and the overall clinical outcome. This method is cheaper, devoid of side effects of drugs and provides a memorable experience to patient.
Aim: This study sets out to investigate the effect of adjunct music therapy on haemodynamic changes in patients undergoing transalveolar mandibular third molar surgery in a tertiary hospital in southwest Nigeria.
Methodology: A total of 146 participants between 21 and 55 years were randomized by balloting into music and non-music groups with equitable gender distribution. For participants in the music group, third molar surgery was performed with selected music tracks played via both external speaker and later headphone while the control group had the stages progress without musical intervention. The blood pressure, pulse rate, respiratory rate were recorded at predetermined interval. Normality of data distribution was tested using Shapiro-Wilk test. Student t-test was used to compare mean for quantitative variables between the groups. The chi-square test was used to compare proportions and to investigate association between categorical variables (p<0.05).
Result and Conclusion: There was no significant difference in the blood pressure, pulse rate and respiratory rate between participants in this study. This suggests that music therapy confers no significant advantage in stabilizing the blood pressure, respiratory and pulse rates of patient during mandibular third molar surgery.
