Abstract
The objective of the study was to convey preoperative patient information on orthognathic surgery, researchers compared the efficiency of multimedia and verbal explanation. The knowledge assessment and multimedia content were created to provide information prior to surgery. A clinical trial was conducted on 34 patients who were randomly assigned into 2 groups, multimedia, or verbal explanation. To test their knowledge, all participants filled out the preintervention and post-intervention questionnaires. For the results, on the posttest, the multimedia group scored 14.2 ± 0.47, whereas the verbal explanation group scored 13.1 ± 2.06. The
Mann-Whitney U test showed a significant difference between the two groups (p < 0.05). For conclusion, the developed multimedia is effective in educating the patient prior to the orthognathic surgery. It can serve as a substitute for a dentist’s direct explanation.
