RESUMO
This study sets out to examine the prevalence of malocclusion and habits in a group of children with cerebral palsy and to compare it with a control group of healthy children. The presence of an anterior open bite was statistically significantly higher in the cerebral palsied group. The presence of aposterior crossbite was not significantly different between the examined groups, as was the case for a lingual crossbite. The occurrence of visceral swallowing, incompetent lips and oral respiration was significantly higher in the cerebral palsied group. The current study cannot satisfactorily sustain the issue of a higher prevalence of posterior and lingual crossbite in children with cerebral palsy because of no significant differences between groups, but it certainly can for an anterior openbite. The present study also adds to the evidence that there is an increased prevalence of oral breathing, visceral swallowing and lip incompetence in children with cerebral palsy.
