Abstract: Objective: The use of multimedia tools improves patient understanding of surgical procedures, reduces anxiety and increases satisfaction. The present study evaluates the impact of an audiovisual intervention (video) upon anxiety and stress in patients requiring an oral biopsy. Material and methods: A prospective randomized clinical trial was carried out in patients requiring an oral biopsy. The control group ( n = 60) received verbal standard information while the experimental group ( n = 60) received information in the form of a video. The following data were recorded: gender, age, educational level and hemodynamic parameters (blood pressure, heart rate and blood oxygen saturation). The following questionnaires were used to assess anxiety and stress before and after the biopsy procedure: Corah’s Modified Dental Anxiety Scale (MDAS), the State-Trait Anxiety Inventory (STAI) and the Hospital Anxiety and Depression Scale (HADS). Results: The final study sample consisted of 120 patients, of which 65.8% were women and 34.2% men, with a mean age of 40.5 ± 15.3 years. At the end of the study, the experimental group presented a significantly lower MDAS score than the control group ( p = 0.041). The STAI score also showed a significant decrease with respect to the control group at the end of the study ( p = 0.012). There were no statistically significant changes in the hemodynamic parameters in either group. Conclusions: The video constituted a useful and easy tool for reducing anxiety among patients requiring an oral biopsy.
