| Outline of Final Research Achievements |
The spectral reflectance of experimental composites showed different trends in different backgrounds, plate thickness, and filler contents. The percent reflectivity tended to decrease with a decrease of the filler contents. The color matching abilities of the experimental composites improved with the increase in the filler contents. Higher filler contents might be needed to achieve the optimal color properties of structural colored flowable resin composites, thereby improving the restoration esthetics.

| Academic Significance and Societal Importance of the Research Achievements |
構造色を応用したフロアブルコンポジットレジンの開発により，その優れた操作性と相まって，簡便で審美的な修復処置が可能となる。さらに，構造色の特徴である，黒色背景での発色の顕著化，あるいは微細構造の変化がなければ色調適合性が損なわれないという工学的特徴から，不要な再修復を減少させることが可能となり，医療経済面においても意義が高い。
