Relation Between Tongue Dimensions and Lower Incisor Crowding

Aim: The aim of this study was to evaluate the relationship between the tongue dimension measurements and lower incisor crowding/position and to identify the possible gender differences. Subjects and Method: Forty-five pretreatment plaster models and cephalometric radiographs of Class 1 patients taken by a standard technique formed the sample for this study. The sample of this study included 22 male (mean age: 15.67 +/- 1.41 years) and 23 female (mean age: 13.86 +/- 1.35 years) patients. Lower incisor crowding was measured with the Little irregularity index. Multivariate statistical analysis was used at p
