Japanese Dentition

This book introduces the achievements of dental anthropology research in Japan to the people in the world. It starts with the tooth morphology of the people in the Paleolithic Period about 20,000 years ago. Then it goes through Jomon Age and Yayoi Age when the admixture of the people happened. Here the difference of the tooth shape between those two human groups is emphasized. After these ages, Japanese teeth were not the same from age to age influenced by the environment. In the current age of Japan, topics such as third molar agenesis, change of eruption time of the first permanent teeth, mandibular torus, and high canine are discussed. These abnormal conditions in Japan also reflect the characteristic features of Japanese history and culture.Contents: ForewordPrologueIntroductionJapanese History OverviewJapanese Dentition:The Paleolithic AgeThe Jomon PeriodThe Yayoi PeriodThe Kofun PeriodThe Medieval Period (The Kamakura Period)The Edo EraRoots of Japanese Dentition:Mongoloid Dental ComplexRoots of Jomon People's TeethRoots of Yayoi People'S TeethTooth Size in Japanese Islands:Eight Regions in Japanese IslandsSecular Change of Total Tooth SizeChanges Before and After the World War IIThird Molar Tooth:Origin of Third MolarSecular Change of the Third Molar AgenesisSize of the Other Teeth in Case of the Third Molar AgenesisEruption Disturbance in the Lower Third MolarRelationship Between the Number of the Erupted Third Molar and StatureCongenitally Missing Teeth:Frequency of Congenitally Missing TeethCongenital Agenesis of the First Molar in Japanese PeopleCharacteristics Dental Traits:History of Dental CariesSecular Change of Mandibular BoneOrder of Eruption Time of the First Molar and the First IncisorMandibular TorusJapanese Thoughts on FangsSex Differences in Size of Human TeethEpilogueAppendixReferencesIndex
