Trastornos del habla asociados a maloclusión dental en pacientes pediátricos

Abstract

The most frequent language disorders among schoolar children, are constituted by pronunciation alterations, known as dyslalias. Harvold suggested that the occlusal and structural abnormalities had a direct relationship to the occurrence of the phonetic alterations. The objective of this study was to determine the association between dyslalia and the malocclusion in children who were attended at the Service of Dentistry of the Institute of Human Communication. The occlusion was evaluated in fifty, five year old patients, diagnosed with delayed language during September/ 2002 to April/2003. It was observed that significant association exists between dental malocclusion and dyslalia (χ2 = 5.78, p < 0.06). Certain dental malpositions can exclude or to hinder the formation of the appropriate constrictions of the vocal tract.
