INTRODUCTION:Patients undergoing endodontic therapy often have severe perioperative and intraoperative anxiety, which may lead to increased perceptions of pain and vital sign instability throughout treatment. The purpose of this study was to test the influences of music, as a nonpharmacologic adjuvant, in terms of significant changes for systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) before, during, and after endodontic treatment in a population with different levels of anxiety assessed with the Corah Dental Anxiety Scale.

METHODS:A total of 100 patients were recruited in the present study; before starting the endodontic treatment, the interviewer administered the Corah Dental Anxiety Scale to the participants to assess the baseline level of anxiety. Patients were randomly divided into 2 groups: the first one listened to the music and the second one did not. Before, during, and after the endodontic procedures, the vital signs (diastolic and systolic blood pressure and heart rate) were recorded. Results were collected and statistically analyzed.

RESULTS:Direct contrasts between patients listening or not listening to music showed that all the measured vital signs decreased considering the overall period (during and after the canal therapy) in the group of patients listening to music (P < .05).

CONCLUSIONS:This study shows the effects of music therapy on vital values and on subjective perception of anxiety during endodontic therapy. Music and medicine always work together; the soothing effects of sounds and musical frequencies make this union an extraordinary tool of synergistic care. Music therapy is a valid nonpharmacologic adjuvant to anxiety perception in endodontic therapies.
