Does Viewing a Third Molar Informed Consent Video Decrease Patients' Anxiety?

PURPOSE: Before having impacted third molars removed, patients are frequently asked to view a brief video describing the operation and its benefits and risks. The purpose of this study was to determine whether such information reduces or increases patients' anxiety level. PATIENTS AND METHODS: In this prospective cohort study, 100 patients presenting for consultation regarding removal of their impacted third molars completed a form asking them to grade their anxiety level before and after viewing the informational video as calm, slightly anxious, moderately anxious, or very anxious. RESULTS: Thirty-one percent reported increased anxiety after viewing the video. Only 12% showed a decrease, and in 57%, there was no change (28% were still slightly, moderately, or very anxious). Scoring of the pre- and post-viewing anxiety levels showed a statistically significant increase in anxiety after viewing. CONCLUSIONS: Viewing the video increased or did not reduce the anxiety level in a significant number of patients. Therefore, it is important to complement this video with positive verbal and written reinforcement of such aspects as patient comfort, procedural safety, and adequate pain control.
