Abstract
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.
