Impact of verbal explanation and modified consent materials on orthodontic informed consent.

Introduction: Comprehension of informed consent information has been problematic. The purposes of this study were to evaluate the effectiveness of a shortened explanation of an established consent method and whether customized slide shows improve the understanding of the risks and limitations of orthodontic treatment.

Methods: Slide shows for each of the 80 subject-parent pairs included the most common core elements, up to 4 patient-specific custom elements, and other general elements.

Informed consent recall and comprehension in orthodontics: traditional vs improved readability and processability methods.

Introduction: Low general and health literacy in the United States means informed consent documents are not well understood by most adults. Methods to improve recall and comprehension of informed consent have not been tested in orthodontics. The purposes of this study were to evaluate (1) recall and comprehension among patients and parents by using the American Association of Orthodontists' (AAO) informed consent form and new forms incorporating improved readability and processability; (2) the association between reading ability, anxiety, and sociodemographic variables and recall and comprehension; and (3) how various domains (treatment, risk, and responsibility) of information are affected by the forms.
