In addition, according to the eruption sequence for permanent teeth that has been used to date, the teeth that erupt earliest are the mandibular first molar and then the mandibular central incisor. However, a large-scale study performed on children born in the 1970s conversely confirmed that the mandibular central incisor erupts earlier than the mandibular first molar. Changes in the eruption sequence are factors that also affect the occlusal morphology of the permanent teeth, and are an important component of the preventive management of childhood caries. If - as reports to date have suggested - the timing of eruption and the eruption sequence are factors that change over time, then we believe further changes in the eruption sequence of the four teeth that erupt earliest can be expected. These four types of teeth are the upper and lower central incisors and the upper and lower first molars. The purpose of the present study was to survey and investigate the eruption status of permanent teeth in recent years. This was achieved by performing dental health checkups on students who were born in 1996 from the time they entered school until they graduated. The study was conducted in four elementary schools in a certain town in Gifu prefecture. We then extracted the state of eruption of the upper and lower first molars and the upper and lower central incisors from the investigation results, and calculated the eruption rate by tooth type and performed a survival analysis using eruption as an endpoint. Results showed that the eruption sequence for male and female children born in 1996 occurred in the following order : mandibular central incisor, then mandibular first molar. This shows that the first permanent teeth to erupt have not changed from the mandibular first molar to the mandibular central incisor since the study performed in 1970.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"大橋","familyNameLang":"ja"},{"familyName":"OHASHI","familyNameLang":"en"}],"givenNames":[{"givenName":"たみえ","givenNameLang":"ja"},{"givenName":"TAMIE","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3916","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000018742950","nameIdentifierScheme":"CiNii
