Modelling of human palate surface development from 7 years to adulthood
Moravec, Tomáš ; Bejdová, Šárka (advisor) ; Zemková, Daniela (referee)
The diploma thesis deals with the differences in the development of the palate in girls and boys within five age groups in the age range of 7 to 19 years, using methods of geometric morphometry. Furthermore, the work deals with the monitoring of sexual dimorphism in the development of the palate. Understanding palate growth, knowledge of differences in its development and changes related to sexual dimorphism are very useful, as the results of this study will serve as a comparative standard for palate defects in the Czech population, but also for appropriate planning of orthodontic procedures. The material consists of 228 gypsum castings of palate without any pathologies, 112 of which belonged to boys and 116 girls of the Czech population. Thus, transverse data are used in our study. The subjects were divided into five age groups 7, 10, 12, 15 and 19 with respect to gender. Age changes of the entire palate surface were modeled using geometric morphometry methods (Coherent point drift - Dense correspondence analysis, Per vertex T- test and Principal component analysis). To visualize the results, superprojection color maps, maps of significance and superprojection. The results show the greatest variability in the form of palate in girls of groups 10 and 12 years and in boys of groups 10 years, and...
