Purpose: The purpose of this study was to determine the effectiveness of immersive visualization (IV) therapy, a technique that provides visual and stereoscopic display through the use of eyewear, in anxious patients during an oral prophylaxis. Methods: A convenience sample of thirty adults was enrolled. A split mouth design was utilized. Subjects were randomly divided into two groups: group A (use of IV for the right side of the mouth), and group B (use of IV for the left side of the mouth). Subjects received a full mouth oral prophylaxis (removal of supra and subgingival calculus and selective polishing), always starting with the right side. Medical and dental histories and oral examinations were performed during the screening appointment. At screening, the Corah's Dental Anxiety Scale- Revised (DAS-R) was scored. In order to qualify for the study, individuals were required to score 9 or higher on the Corah's DAS-R, present with no severe dental calculus, severe periodontal disease, or severe dental caries. At baseline the Corah's DAS-R was validated, and the Calmness Scale was scored pre- and post IV treatment. During treatment, subjects had the opportunity to select one of three IV videos: (1) documentary, (2) music videos, or (3) TV show. After the completion of the full mouth prophylaxis, subjects completed a Post IV Opinion Survey. Results: Twenty-three females and 7 males participated in the study ( age 29.96 ± 7.8). The results showed no statistically significant difference at the level of 0.05, between groups with regard to the anxiety level at baseline based on Corah's DAS-R (p = 0.69). There was a statistically significant correlation between Calmness Scale and gender (p = 0.01 ), females report higher levels of anxiety than men. Ninety seven percent of the subjects responded positively to the use of IV eyewear during the treatment. Conclusion: The use of IV eyewear during oral prophylaxis can be an effective method to control anxiety.
