ABSTRACT
@#BACKGROUND. The aim of this study was to analyze craniofacial sagittal and vertical dimensions in subjects with normal occlusions to establish age and gender-specific lateral cephalometric measurement standards for Mongolian children. MATERIAL AND METHODS. The study group consisted of a sample of 642 untreated subjects with normal occlusions from 6 to 15 year old. Craniofacial anatomic landmarks were identified directly on the digital images. A customized cephalometric analysis was used to measure 18 variables of linear measurement and 18 variables of angular measurement on software program (Winceph 11.0). Student’s t-test was employed to test for gender differences in each age. RESULTS. Most of the linear measurements, larger craniofacial distances were recorded in males than females. Also linear measurements were increasing according to age. There were no statistically significant gender differences with regard to most angular measurements at subsequent age groups. Soft tissue analysis revealed flatter profiles in females than in males from the age of 10-11 years onward, while age-dependent changes in the soft tissue profile were similar in both genders. СONCLUSION. In untreated subjects with normal occlusion craniofacial development of the hard can be considered age- and gender-dependent. Therefore age- and gender-specific differences of linear craniofacial distances should be taken into account for diagnosis and treatment planning in children and adolescents. The present results can be used as reference values for children and adolescents of Mongolian origin.
