The present invention relates to a novel use of a mineral trioxide aggregate (MTA)-based coating composition for sensitive teeth, and more specifically, to a teeth coating composition, containing an MTA ingredient, for preventing or treating a dental hypersensitivity symptom of sensitive teeth by effectively sealing the dentinal tubule on the surface of the teeth when coated on the outer portion of the sensitive teeth.La présente invention concerne une nouvelle utilisation d'une composition de revêtement à base d'un agrégat de trioxyde minéral (MTA) pour dents sensibles et, plus particulièrement, une composition de revêtement de dents, contenant un ingrédient de type MTA, destinée à prévenir ou à traiter un symptôme d'hypersensibilité dentaire de dents sensibles par le scellement efficace des tubules de la dentine à la surface des dents lorsqu'elle est revêtue sur la partie extérieure des dents sensibles.본 발명은 민감성 치아용 MTA(Mineral Trioxide Aggregate)계 코팅 조성물의 신규한 용도에 관한 것으로서, 더욱 상세하게는 MTA 성분을 포함하여, 민감성 치아의 외부에 도포될 경우 치아 표면의 상아세관을 효과적으로 밀폐하여 민감성 치아의 시린이 증상을 예방 또는 치료할 수 있는 치아 코팅용 조성물에 관한 것이다.
