Palatal arch diameters of patients with allergic rhinitis

ABSTRACT

The purpose of this study was to evaluate the transverse and vertical dimensions of the palate of children with allergic rhinitis [AR]. There was no significant difference for intermolar and intercanine distances between two groups in primary and mixed dentitions. Palate depth in children with allergic rhinitis was statistically more than in children without any respiratory disease. Cross bite was more prevalent in study group. It seems that the main influence of alteration of breathing pattern from nasal to mouth occurs on the vertical plane
