| Outline of Final Research Achievements |
To clarify the effects of social and environmental factors during pregnancy and childhood on the onset of malocclusion and the influence of malocclusion on physical and mental health, we conducted a survey of all students (age, 12-15 years) enrolled in every junior high school (schools N = 5) in Koshu City. Koshu City is the field study area for Project Koshu, an ongoing prospective birth cohort study.
As a result, a longitudinal population-based study revealed an association between maternal smoking habits and the development of permanent tooth defects in their children. These results provide fundamental data for elucidating the mechanisms by which maternal smoking influences permanent tooth loss in children.

| Academic Significance and Societal Importance of the Research Achievements |
本研究にて明らかとなった不正咬合の発症要因、および不正咬合が健康状態に与える影響は、今後の不正咬合の予防・治療の政策を立案する上で重要な論理的基盤となり、結果として子どもの健康状態を改善することが可能となる。さらに本研究は自治体が主体で行っているため、学校や社会への還元が行いやすい環境にある。よって、不正咬合の予防政策の立案及び実施のモデルとなる可能性が期待できる。
