Posture and posterior crossbite in oral and nasal breathing children

Abstract

The most known etiologic factors of oral breathing may influence the craniofacial development leading to anatomical and functional alterations. A proper head and cervical spine posture allows a well functioning of the stomatognathic system structures and vice versa. This study was conducted to evaluate the prevalence of posterior crossbite in a group of oral breathing children (OB) and nasal (NB) and associate the type of bite with the head and cervical spine posture. It was concluded that most of the children, either oral or nasal breathers, did not present a crossbite and any kind of head posture and cervical spine can vary independently of a posterior crossbite.
