Abstract:
Objective:To compare the morphology of dental arch and base bone between oral breathing and nasal breathing children.Methods: A simultaneous measurement system was applied to test oral and nasal respiration.34 oral breathing children and 34 nasal breathing children aged 11 to 14 years old were selected.The parameters of the morphology of dental arch a nd base bone were measured on the record models.Results:① The oral breathing children showed higher palatal vault,and narrower maxillary b ase bone.The configurations of maxillary base bone were comparatively narrower a nd longer.②The oral breathing children's medial and posterior parts of arches o f maxilla were longer,and the configurations of maxillary arch were comparativel y narrower and longer.The configurations of mandible posterior arch were compara tively narrower and longer too.Conclusion:Oral breathing m ay lead to morphological changes in dental arch and base bone in children.
