Contributions to the study of the prevalence of oral breathing associated with angle class II/1 malocclusion

Abstract

The obstruction of nasal passages determines the disturbance of the function of normal breathing, once the oral breathing is settled. The aim of the present paper is to bring a contribution to the analysis of the prevalence of oral breathing in the etiology of Angle Class II/1 malocclusion. 1,735 children aged 6 to 14/15 from the area of Craiova were part of the present study. The research has revealed a prevalence of 7,24% in the urban area and 6,47% in the rural one. The result is that, once the oral breathing is permanently settled, there may appear disorders in the cranio-facial development, sometimes leading to the appearance of Angle Class II/1 malocclusion.
