Title
(EN) COMPOSITION FOR ORAL CAVITY
(FR) COMPOSITION POUR LA CAVITÉ BUCCALE
(JA) 口腔用組成物
Abstract
(EN)
Provided is a composition for an oral cavity, the composition containing particles that have dentinal tubule-sealing properties and excellent fixation inside the dentinal tubules. More specifically, the present invention provides a hydroxyapatite particle-containing composition for an oral cavity, wherein the ratio of a diffraction peak intensity around 2θ=32° to a diffraction peak intensity around 2θ=26° of the hydroxyapatite particles is 0.8-1.6 in an x-ray powder diffraction pattern measured using Cu-Kα characteristic x-rays.
(FR)
L'invention fournit une composition pour la cavité buccale qui présente des propriétés de scellement du tubule dentinaire, et qui comprend des particules excellentes en termes d'adhérence à l'intérieur du tubule dentinaire. Plus spécifiquement, l'invention fournit une composition pour la cavité buccale qui comprend des particules d'hydroxyapatite. Lesdites particules d'hydroxyapatite présentent un rapport de l'intensité de pic de diffraction autour de 2θ=32° vis-à-vis de l'intensité de pic de diffraction autour de 2θ=26° dans un motif de diffraction de rayons X sur poudres mesuré par un rayon X spécifique CuKα.
(JA)
象牙細管の封鎖性を有し、且つ象牙細管内での固着性に優れた粒子を含有する口腔用組成物が提供される。 具体的には、ヒドロキシアパタイト粒子を含有する口腔用組成物であって、前記ヒドロキシアパタイト粒子が、CuKα特性X線により測定される粉末X線回折パターンにおける2θ=26°付近の回折ピーク強度に対する2θ=32°付近の回折ピーク強度の比が0.8~1.6である、口腔用組成物が提供される。
