A study on the eruption timing of primary teeth in Korean children.
The objectives of this study were to clarify the eruption time and sequence of primary teeth in Korean children. A random sample of 1070 children from ages of four to thirty-six months was examined: 567 were males and 503 were females. The median values to measure the eruption time of the primary teeth were used. The results show that the primary teeth of boys erupt earlier than those of girls. As to the eruption sequence of primary teeth, the mandibular central incisor and second molar erupted earlier than their maxillary counterparts. For the lateral incisor, the canine and the first molar, the maxillary teeth erupted before the mandibular ones.
