OBJECTIVE: The purpose of this study was to investigate the effect of a portable video eyewear entertainment system used in conjunction with nitrous oxide/oxygen sedation during the removal of impacted lower third molars. STUDY DESIGN: Thirty-eight patients had their bilateral third molars removed under local anesthesia and nitrous oxide/oxygen inhalation sedation in 2 visits. On one side, video eyewear was used (group NE). On the other side, the tooth was removed without the use of video eyewear (group N). Vital signs were monitored. Overall behavior and the outcome of treatment were assessed. RESULTS: All 38 patients completed the study. The mean scores on behavior rating in group NE were significantly higher than those in group N (P < .05). The majority of patients (92.1%) preferred nitrous oxide with video eyewear. CONCLUSIONS: The use of video eyewear appeared to augment the effectiveness of nitrous oxide sedation in dental extraction patients.
