    摘要: The invention relates to a multi-component dental cement which contains as a first component an ethylenically unsaturated polymerisable compound, as a second component calcium hydroxide, calcium oxide or a precursor thereof and also a polymerisation initiator, the constituents of which can be contained in one or more cement components, which is characterized in that the ethylenically unsaturated polymerisable compound has both at least one .beta.-dicarbonyl group and also at least one acrylic, alkacrylic or vinyl aromatic group. Also included are a process for the production of a multi-component dental cement and the use of the described polymerisable .beta.-dicarbonyl compounds in calcium hydroxide dental cements.

    摘要: An applicator kit, for dental purposes. has an application element with a grip area for handling, and also has a shaft, on a tip of which is disposed an application member, preferably in the form of a micro-brush that is provided with a reaction substance. A cup shaped sealing mechanism surrounds the shaft and the application member. The cup shaped sealing mechanism is slidably received within a housing which also receives a low velocity fluid initially spaced away from the cup-shaped sealing mechanism. The reaction substance on the application member is activated by pressing the sealing mechanism and application member into the fluid within the housing which causes the fluid to wet the application member.
