Introduction: Informed consent is common to all invasive procedures in medicine, dentistry and human research. Studies have shown there is a paradox between the ideal legal and ethical position of full autonomy over the decision to consent and the reality that patients do not fully understand all the issues when giving informed consent.

Objectives: To determine if the method of delivery of the advice at informed consent would influence the level of knowledge of patients and parents, and to evaluate which areas of risk in orthodontic treatment were known or not known before and after the consent process.

Method: Ninety-nine families (one child and one parent) were split randomly into three groups. Each group was informed by a different method of communication. Group A received the traditional verbal consent method, Group B received a DVD video, and Group C was the control with no information given. The groups were tested by questionnaire before (Tl) and after (T2) the consent appointment, for recall of the risks in orthodontics.

Results: ANOVA was performed to differentiate between the groups for each of the areas of risk tested. The parent groups showed a significant increase in knowledge with both methods of consent (p<0.05), but the mean increase relative to controls was small and below ideal levels of knowledge. The child groups showed a significant increase in recall only in the DVD video group when compared to the control (p<0.01). Individual areas of consent specific to orthodontics such as root resorption showed a greater increase in knowledge and final understanding than general dental risks such as oral hygiene and gingival health.

Conclusions: Overall, recall of informed consent risks for all groups was below ideal levels required for the parents and children to have full autonomy over the consent decision. The DVD video outperformed the traditional verbal consent process in children but not parents. Specific areas of consent to orthodontics were remembered better than more general areas related to oral health.
