Effects of Music and Aromatherapy on Blood Pressure and Heart Rate Among Endodontic Patients: A Randomized Clinical Trial.

OBJECTIVES

Music and aromatherapy are recognized as noninvasive methods for promoting relaxation. Endodontic treatment is often perceived as a stressful procedure in dental settings. This study aimed to assess the effects of these interventions on blood pressure and heart rate among patients undergoing root canal therapy.

MATERIAL AND

METHODS

In this single-blind, parallel-group, randomized clinical trial, 72 adult patients diagnosed with irreversible pulpitis and normal periapical conditions were referred to a dental school for endodontic treatment. Participants were randomly assigned to one of four groups: (1) control group, (2) music group (participants listened to tracks of Stefano Crespan Shantam, tuned to 432 Hz), (3) aromatherapy group (participants were exposed to five drops of lavender oil via a humidifier), and (4) combined music and aromatherapy group. Blood pressure and heart rate were measured before and after the intervention. Data were analyzed using SPSS software and one-way ANOVA.

RESULTS

Although systolic and diastolic blood pressure, as well as heart rate, decreased in the intervention groups, there were no statistically significant differences compared to the control group (p > 0.05).

CONCLUSIONS

Music and aromatherapy did not produce statistically significant reductions in blood pressure and heart rate among endodontic patients. Alternative methods should be explored to manage patient anxiety better.
