Introduction: Frowine and Moser showed that the malocclusion was independent speaking. Rathbone said that a relationship exists between the poor and I malocclusion, but no direct effect on the severity of malocclusion and speech. Hopkin and McEwen found that speech defects could occur in a normal occlusion in maloclusiones.
Objective: To determine the prevalence of malocclusions related to language problems.
Materials and Methods: A descriptive cross-sectional study, prolectivo observational in kindergarten Antonia Nava de Catalan located east of the city of Mexico. The study population consisted of 94 preschoolers, 53% (n = 50) male and 47% (n = 44) female. The average age was 4.9 (± 0.7).
Results: The analysis of the types of malocclusion in relation to language disorders, 60% of preschool children with type 2 arc of Baume disorders of language. Children who have alterations in the 78% bite problems in language. As far as the mesial and distal terminal plane exaggerated 60% of children with speech disorders have disturbances of language. In analyzing malocclusions as risk factors the value of the indirect risk was <1 indicating that act as protective factors.
Conclusions: The presence of malocclusions in infants as they are, the arc of Baume type 2, the anterior open bite and cross-level and subsequent mesial and distal terminal exaggerated, could be considered as protective factors for not developing language problems.
