title: [Orthodontic abnormalities of deciduous and permanent occlusion].
abstract: The aim of this study was to examine the trend in orthodontic anomalies for the period from primary to permanent dentition. 246 examinees (132 boys and 114 girls) with orthodontic anomalies were examined for the first time at the age of 4.5-5.5. These examinees were reexamined by the same orthodont at the age of 12.5-13.5. No orthodontic procedures were performed with the children in the meantime. From the period of primary to permanent dentition, 16.3% of orthodontic anomalies developed into eugnathia. During this period, the incidence of Class II Division I anomalies, premature tooth loss and open bite significantly decreased, and the incidence of Class II Division 2 and crowding increased. From primary to permanent dentition 63.4% orthodontic anomalies altered, and 36.6% remained with a stabile diagnosis.
