Sleep-disordered breathing (SDB) ranges from snoring to sleep apnea. In children and adolescents, 3-27% snore and 1-10% have apnea. Breathing problems during sleep in children and youth are associated with health, learning and behavior problems. While big tonsils and adenoids often cause SDB in children, face and jaw shape are also responsible. Orthodontic treatments guide face and jaw growth. This will help to reposition the tongue and to improve swallowing. Orthodontic treatments work best during the growth of a child and are seen as non-invasive. It is then interesting to prevent or treat SDB in children this way.
This research program will describe and measure face and jaw growth linked with the start of SDB. It will measure the impact of the orthodontic treatments on breathing during sleep in children. Improving the upper airway by guiding face and jaw growth will improve breathing during sleep.

This will have positive impact on general health, learning and behavior of children. Questionnaires, measures of upper airway and breathing, and sleep studies at home with a small portable device will be done at various times and treatments. SDB treatment in children can help preventing it in adults. This research can help create new practice parameters of orthodontic treatments in children with SDB due to face and jaw uneven growth resulting in upper airway narrowing.
