Outline of Final Research Achievements

In order to understand in detail the effects of acquired factors on jawbone morphogenesis, we developed a unique morphological comparison method using micro 3DCT to examine the morphological changes in mouse jawbone caused by feeding powdered and solid diets with the same ingredients. and published a paper on the effects of dietary differences on the morphology of the mandibular bones of mice.
In 2020, we reported the effects of dietary differences on the morphology of the maxilla in mice.
In 2022, we used principal component analysis to analyze topological changes across samples to identify factors that explain morphological differences between powdered and chow samples. In addition, based on the analytical results, canonical variate analysis was used to identify morphological features that account for differences between powdered and solid food samples.

Academic Significance and Societal Importance of the Research Achievements

本研究は、環境要因がエピジェネティック制御に影響を与え、その結果、形態形成異常が生じるという全く新しい概念を提案するものであり、学術的独創性が高い。その知識基盤が確立されれば、不正咬合患者の診断において、特定の遺伝子のエピジェネティック変異があるかどうかを調べることにより、成長予測や治療効果の予測が行えるようになるかもしれない。さらに薬剤の投与によってそれをコントロールすることができれば将来の矯正歯科治療における治療の一つのありかたに大きな変化をもたらすことができる。このように、本研究がもたらす研究結果は学術的意義、社会的意義が非常に高いと考えられる。
