PROBLEM TO BE SOLVED: To develop a method for testing by which durability of a curable material for producing a dental restoration comprising an acrylic or a methacrylic ester-based polymerizable monomer as a curing component after use thereof can be tested and accurately judged according to a simple technique in a short time.SOLUTION: The method for testing the durability of the curable material for producing the dental restoration comprising the acrylic or methacrylic ester-based polymerizable monomer after use in dental restoration before the use is characterized as follows. The cured material of the curable material for producing the dental restoration is brought into contact with a solution of a basic dye, specifically magenta, methylene blue, etc., to judge the dyed state thereof.COPYRIGHT: (C)2008,JPO&INPIT【課題】硬化成分として(メタ)アクリル酸エステル系重合性単量体を含む歯科修復物製造用硬化性材料に対する、その使用後の耐用性について、簡便な手法で短時間に実施でき、正確性良く判断できる検査方法を開発すること。【解決手段】(メタ)アクリル酸エステル系重合性単量体を含む歯科修復物製造用硬化性材料の、歯牙修復に使用後の耐用性を使用前において検査する方法であって、該歯科修復物製造用硬化性材料の硬化物を塩基性染料、具体的にはマゼンタやメチレンブルー等の溶液に接触させて、その染色状態を判定することを特徴とする歯科修復物製造用硬化性材料の耐用性検査方法。【選択図】 なし
