Zaburzenia artykulacji a funkcje fizjologiczne układu stomatognatycznego u młodzieży szkolnej
Articulatory disorders and physiological functions of stomatognathic system among primary school children

Summary/Abstract: Dysfunctions of the stomatognathic system, such as inappropriate breathing, swallowing or chewing function, may lead to speech defects due to lowered muscle tension or motor efficiency, especially of the tongue or lips. This paper presents the findings of the logopedic research conducted on 115 students sixth graders, constituting the entire population in the examined age groups. The results indicate a high number of articulatory disorders − 83%. Functional abnormalities were found in a smaller number of the examined students, respectively: breathing disfunction – 18 per cent, swallowing disfunction – 30 per cent, inappropriate placing of tongue at rest – 33 per cent, lowered tongue and lips efficiency – 27 per cent. A comparison of the quantitative data revealed that in the groups of young people with inappropriate physiological functions there are more speech defects. The statistical analysis confirmed two essential correlations: the way of swallowing and the position of the tongue at rest have the influence on the quality of articulation. Articulatory disorders were confirmed in all the children with parafunctions in the stomatognathic system. The findings are alarming because of the epidemiology of the observed phenomena in children.
