Contexte : Les effets de la succion sur les structures dento-faciales ont été largement étudiés, mais sa relation avec la fonction et/ou la forme du palais a été négligée. Une voute palatine haute est classiquement associée aux habitudes de succion ; ces constatations sont issues d'observations cliniques, mais ne se basent pas sur des études statistiques. L'objectif de ce travail est de comparer les résultats obtenus à une population témoin.
Méthode : A partir d'un questionnaire rempli par les parents le comportement de succion de 250 enfants âgés de 3 à 5 ans a été colligé. Les paramètres étudiés étaient la largeur, la profondeur et la hauteur du palais mesuré directement à partir des moulages maxillaires des enfants et ainsi l'indice palatin a été calculé. Toutes les valeurs ont été comparées en utilisant le test t de Student.
Résultats : Des différences significatives ont été observées dans la profondeur, la largeur, la hauteur et l'indice palatin au niveau des premières et secondes molaires. Aucune différence significative n'a été observée au pour l'index palatin en ce qui concerne les premières canines maxillaires.
Conclusion : Il a été conclu que la succion pouvait entraîner des modifications dans les dimensions du palais.
Background: The effects of digit sucking on dentofacial structures has been widely studied, but its relationship with the function and/or shape of the palate has been neglected. A clinical observation of high palatal vault has been reportedly associated with digit sucking. However, the description has been made on the basis of subjective clinical observation rather than actual measurements. The aim of this study is to assess the effects of digit sucking habits on palatal dimensions of children with digit sucking habit; and compare the findings obtained to a control population.
Method: Cross-sectional sucking behaviour data was collected on 250 school children aged 3 to 5 years using questionnaires completed by parents. Parameters including palatal widths, depth and heights were measured directly from the maxillary casts obtained from the children and palatal index was calculated. All values were compared using t-test.
Results: Significant differences were seen in palatal depth, palatal width, palatal height and palatal index at the level of the maxillary primary first and second molars. No significant difference was observed for palatal index at the level of the maxillary primary canine.
Conclusions: It was concluded that digit sucking may cause changes in palatal dimensions.
