Summary

This study looked at whether the way a child's jaw is aligned (called skeletal malocclusion) affects their sleep quality. Researchers studied 164 children aged 7 to 13 who had no other mouth or breathing problems. They measured sleep using a parent questionnaire and took X-rays to check jaw and airway measurements. The goal was to see if jaw position alone can impact how well children sleep.
