Resumen:
The apical area is the space in the maxillary bones that contains teeth during formation and is subsequently occupied by the apices of the permanent teeth. Its dimensions are easy to perceive and determine by observing a panoramic X-ray. Our objective was to analyze the influence of crossbite on the size of the anterior and mesial apical area in Caucasian children.
Based on the ortopantomograph of 353 patients in mixed dentition and crossbite, the sizes of the apical areas of the four hemiarches were studied using the Tps Dig Version 2® computer program. These data were subjected to statistical analysis using the SPSS 22.0 for Windows program and applying the methods of descriptive statistics of quantitative variables, the Kolmogorov-Smirnov test, the non-parametric test Mann-Whitney-Wilcoxon test, and the paired Student t-test.
In the group of boys, average values in the superior-mesial, superior-anterior, inferior-mesial and inferior-anterior apical areas of the crossbite were 173.43, 99.85, 180.32 and 87.56 respectively, with the lower values being in the hemiarch without malocclusion. In the group of girls, for the same apical areas, average values were 165.64, 94.24, 168.62 and 83.34 r...
