THE FREQUENCY OF ORAL BREATHING AND DENTALMAXILLARY ANOMALIES IN A GROUP OF CHILDREN
Abstract:
For a normal growth and development of oral and nasal cavity, the lip orifice in repose should be closed, there should be an anterior contact between the top of the tongue and the lingual surfaces of upper incisors and the tongue base should have contact with the soft palate. The purpose of this study is to determine the prevalence of incompetent lip seal in a collectivity of children and to contribute to the elucidation of the relationship existent between the incompetent lip seal and dental-maxillary anomalies. Within the studied group composed of 74 children, boys and girls, I observed an increased prevalence of incompetent lip seal. Dental-maxillary anomalies are more frequent at children with incompetent lip seal and the values average of the transversal growth of dental arches is lower in individuals with incompetent lip seal than in individuals with competent lip seal.
