摘要：The aim of this research was to determine the existence of asymmetry in the root development of the first and second permanent molar at different ages. The research was carried out based on orthopantomographic X-ray images of 523 children ( 253 boys and 270 girls), 6-14 years of age, who were orthodontic patients at the Dental Clinic of Nis. Asymmetry in the root development of the first and second permanent molar was analyzed by means of Gleiser's and Hunt's method, Tijanic's modification (1981). Asymmetric M1 root development is not present in any of the examinees. Asymmetric M2 root development is present in a total of 28 children (5,35 %), in 15 boys (5,93 %) and in 13 girls (4,81%). The difference in the stages of root formation is within the limits of one stage. Asymmetric root development is most often present in 5th and 6th stage, 46,67 % in boys and 38,4 % in girls. The next most prominent stages are 7th and 8th, 33,33 % in boys and 32,14 % in girls. Asymmetry in the root development of the lower, first permanent molar is not present in the examined samples, while asymmetry of the root development of the second lower permanent molar is present in the lower stages of development.
