ClinConnect Summary

This clinical trial is studying how certain orthodontic treatments, specifically mandibular advancement (moving the lower jaw forward) and maxillary expansion (widening the upper jaw), can improve breathing in children with specific dental issues. Researchers want to see if these treatments can increase the space in the upper airway, which might help children breathe more easily. They aim to find out if changes in the shape or size of the airway can lead to better airflow and less effort when breathing. This is important because breathing difficulties in children can lead to problems with behavior and learning.

To participate in this study, children aged 8 to 14 years old who have certain dental conditions may be eligible. Specifically, the trial is looking for boys aged 9-14 and girls aged 8-12 who have a specific type of bite issue known as skeletal class II division 1 malocclusion, along with a narrower upper jaw. However, children with certain health problems or those who have had previous orthodontic treatments may not qualify. Participants can expect to undergo assessments to measure their airway volume and airflow both before and after treatment, helping researchers understand how these orthodontic techniques can make breathing easier for kids.
