[Eruption times of permanent teeth in children and adolescents of Paderborn, Westphalia, Germany]

Abstract

The eruption times of permanent teeth and the sequence of tooth eruption were investigated in 1535 individuals aged 3 to 24 years. Wisdom teeth were excluded from the evaluation. All individuals were inhabitants of Paderborn, Westphalia, Germany. The results were compared to results of other German studies on tooth eruption of the 20th century. The teeth emerged symmetrically in each jaw. However, teeth erupted earlier in the mandible than in the maxilla. Teeth erupted earlier in females than in males. The sequence of emerging teeth in the maxilla is identical in both sexes: first molar, central incisor, lateral incisor, first premolar, and canine, second premolar, second molar. The sequence of tooth eruption of the mandible is identical in both sexes but differs from the maxillary sequence: first molar, central incisor, lateral incisor, canine, first premolar, second premolar, second molar. Since the fifties of the last century the acceleration of teeth emergence has not increased in German studies on this subject.
