Surface Structure Study of Crystal Hydroxy-Apatite from Fluorosis Enamels
Fluorosis is a condition due to ingestion of excessive amounts of fluor which can cause the change in tooth structure and strength. However, there is still lack of explanation on the surface structure of crystal hydroxyapatite that influences the ...

Changes in the Enamel Protein during Enamel Formation
幼若エナメル質中に含まれている有機質のほとんどを占めている蛋白質は多成分系である事が知られている。それらのうちのどの成分が生理的に重要なのかを明らかにする目的で, 先ずラット幼若エナメル蛋白質についてゲル濾過クロマトグラフィーとSDS-ポリアクリルアミドゲル電気泳動を行なって, 石灰化の進行に伴う蛋白質のパターンの変化を調べた。続いて, ラットに3H-prolineを静注し, そのエナメル質への取込みの時間的な変化をゲル濾過クロマトグラフィーとポリアクリルアミドゲル電気泳動を行なって調べた。その結果は若いstageのmain componentである分子量約20, 000のproline, glutamic acid, histidineに富む成分が初期に多く脱却し, 石灰化が進むに従って分子量15,

Abstract Background Autogenous particulate dentin has emerged as one of the promising biocompatible alternatives to traditional bone graft materials in alveolar ridge augmentation. Although its clinical success is documented, comprehensive studies combining histological and radiographic evaluations remain limited. This case report addresses this gap by
