The aim of our research is to establish a link between malocclusions and oral dysfunctions. The clinical examination includes: caries screening (DMFT and dft scores), a quantification of dental plaque (Silness and Loë's plaque index) and orthodontic treatment need (Haute Autorité de Santé HAS). The functional examination includes improper mouth breathing, abnormal deglutition and incorrect position of tongue at rest.
