[Eruption times of permanent teeth in children and adolescents in the German state of Saarland]

Abstract

The eruption times of permanent teeth and the sequence of tooth eruption were investigated in 1,856 individuals aged 4 to 24 years (female: 912, male: 944). Wisdom teeth were excluded from the evaluation. All individuals were inhabitants of the German state of Saarland. The results were compared to results of national and international studies on tooth eruption of the 20th century and studies published in recent years. The teeth emerged symmetrically in each jaw. However, teeth erupted earlier in the mandible than in the maxilla, excluding the slightly earlier eruption of maxillary premolars and first molars in males. The sequence of emerging teeth in the maxilla of females is: first molar, central incisor, lateral incisor, first premolar, canine, second premolar, and second molar. The sequence of tooth eruption of the mandible of females differs from the maxillary sequence: first molar, central incisor, lateral incisor, canine, first premolar, second premolar, second molar. The sequence of emerging teeth in the maxilla of males is: first molar, central incisor, lateral incisor, first premolar, second premolar, canine, and second molar. The sequence of tooth eruption of the mandible of males differs from the maxillary sequence: first molar, central incisor, lateral incisor, first premolar, canine, second premolar, second molar. The results of this study are in accordance with those from other current studies of German federal states, obtained by the same method.
