Description
本出願は、2004年11月9日出願の米国仮特許出願第60/626,407号“Tooth Whitening Compositions”、2004年11月26日出願の第60/631,121号“Whitening System”、2005年1月22日出願の第60/643,309号“Dental Whitening”、および2005年2月15日出願の第60/653,421号“Whitening System Capable of Effective Whitening Action”の便益を主張し、これらの内容は参照により本開示に含まれる。
本発明は、歯牙漂白組成物に関する。特に、本発明は、2成分の歯牙漂白系に関する。
(a) 少なくとも1種の過酸化物を含んだ第1のゲル成分を調製する;
(b) 過酸化物ゲルの漂白作用を触媒できる少なくとも1種の遷移金属化合物を含んだ活性剤ゲルを調製する;
(c) 歯牙へ過酸化物ゲルおよび活性剤ゲルを塗布する;
(e) 歯牙に光を照射する;
ステップを含み、
前記漂白系は、非発泡、泡状、または発泡性の状態とできる方法を提供する。
第1のゲル成分が少なくとも1種の過酸化物を含み、第2のゲル成分が、少なくとも1種の、過酸化物の漂白作用を触媒し、標準的またはより低濃度の過酸化物でより効果的な漂白作用をもたらすための低酸化状態の遷移金属化合物を含む口腔へ使用可能な活性剤ゲルを含む、2成分の漂白ゲルと、
重量比で約3%から約5%のアルカリ金属塩(硝酸カリウムなど)と、約1100ppm以下の濃度のフッ化物イオンの源を含み、2成分の漂白ゲルと同程度の粘度を有する、1成分の粘性ゲルと、
を含む、過敏性低減効果を有する歯牙漂白系を提供する。
エナメル質、象牙質、および獲得被膜である。歯牙のエナメル質は主に、無機質からなり、その大部分はヒドロキシアパタイト結晶の形をとり、さらに、主にコラーゲンという形で約5%の有機物も含みうる。これに対し、象牙質はその20%がコラーゲンを含むタンパク質で構成され、残りは無機質、主に、エナメル質においてみられるのと同様のヒドロキシアパタイト結晶からなる。獲得被膜は、歯牙の表面に連続的に形成される、タンパク層またはタンパクマトリックスである。獲得被膜は強度の機械的清掃によって剥離することがあるが、その後すぐ、迅速に再生する。
