This study aims to evaluate the video modeling technique during the dental appointment. A blinded randomized clinical trial was composed of 2 groups, consisting of 20 autistic children (4 to 12 years) in each group: control (did not watch the video before the consultation) and intervention (watched the video before the consultation). The primary outcome was the mean number of visits to perform a dental appointment. The number of consultations was analyzed by T-test or Mann-Whitney test. The results showed that the mean number of consultations in the intervention group was 1.5 (± 1.53) and in the control group 2 (± 1.77) (p [less than or equal to] 0.05). The video modeling technique can be effective in minimizing the number of dental consultations in autistic children.
