Abstract: Provided is a seal device, which can reliably prevent leakage of substances from a gap in a coupling portion for two flow paths while improving ease of operation at the time of coupling the two flow paths to each other and decoupling the two flow paths from each other. The seal device includes: a first flow path (16A) which allows substances to pass therethrough; a second flow path (16B) separably coupled to the first flow path (16A); a sealing member (52), which has elasticity, and is held in a gap in a coupling portion (15) between the first flow path (16A) and the second flow path (16B); and a movable member (30) that closes the gap in the coupling portion (15) by deforming the sealing member (52) when the first flow path (16A) and the second flow path (16B) are to be coupled to each other.

Abstract: It is intended to provide a remineralization promoter for tooth enamel and a composition for an oral cavity, which can highly effectively promote the remineralization of tooth enamel and strongly inhibit dental caries. The remineralization promoter for tooth enamel and the composition for an oral cavity are characterized by containing amorphous hydroxyapatite and/or amorphized hydroxyapatite showing two peaks at 2θ = 31 to 35° in X-ray diffraction. The amorphized hydroxyapatite is obtained by reacting calcium salt with phosphate in an aqueous solution and drying the reaction solution at a temperature of 10 to 70°C.
