Title Using A Noise Canceling Audio Device As A Means To Help Calm A Dental Patient With Anxiety
Clinical Question In an anxious patient, does a noise canceling audio device have the ability to relax the patient more than an audio device alone?
Clinical Bottom Line More research is needed to conclude whether a noise canceling audio device is more effective at reducing dental anxiety than an audio device alone. However, research does conclude that music distraction is successful in reducing a patient’s anxiety during dental treatment. (See Comments on the CAT below)

PubMed ID Author / Year Patient Group Study type
(level of evidence)
#1) 15259973Canbek/2004254 Healthy patients from the university clinic with an average age of 32Crossover Study
Key resultsThe use of masking noises in a test period of 15 minutes led to a significant reduction (p = 0.0017) in patient’s perceptions of noise experienced during dental treatment compared to no masking noise.
#2) 18310736Lahman/2008Patients with dental anxietyRandomized Control Trial
Key resultsWhile music distraction resulted in a significant reduction in anxiety state in comparison with no intervention (C) (P < .05), the anxiety reduction following brief relaxation was greater than that in the control (P < .001) and music distraction (P < .001) groups.

Comments on
The Evidence
Both study designs included groups that were similar at the start with greater than 80% completion rate and adequate follow-up. The 2004 study treated the treatment group the same whereas the 2008 study treated the groups differently. Neither study used double-blind randomization and had little to no recall bias or competing interests.
Applicability Both studies are applicable to patients who experience anxiety prior to routine dental treatment, not including those patients who are phobic or have experienced psychological trauma from prior treatment.

A PubMed search for anxiety and noise on January 2014 only found a limited number of resources pertaining to multiple disciplines. PubMed: 24358573 did not pertain directly to dentistry but discussed music therapy in addition to analgesics for postoperative pain management.
