The present invention provides a dental hydraulic temporary sealing material composition on which a protection of tooth substance, such as tooth substance strengthening and control of secondary dental caries, can be expected by sustained-releasing various ions including a fluoride ion, while having a high initial setting ability. More specifically, the present invention provides a dental hydraulic temporary sealing material composition comprising 65.0% to 85.0% by mass of component (1): a hydraulic inorganic powder; 10.0% to 25.0% by mass of component (2): an organic solvent; 3.0% to 15.0% by mass of component (3): a resin; and 0.01% to 10.0% by mass of component (4): an ion sustained-release glass.

The present invention relates to a kit of parts comprising Paste (A), Paste (B) and Paste (C), the pastes being characterized as follows: Paste (A) comprising at least one polyorganosiloxane with at least two olefinically unsaturated groups, and at least one organohydrogenpolysiloxane, at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s); Paste (B) comprising at least one polyorganosiloxane optionally with olefinically unsaturated groups, at least one addition cure catalyst, optionally at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s) Paste (C) comprising a softener, a condensation cure catalyst, optionally filler(s), and optionally additive(s) optionally at least one polyorganosiloxane optionally with olefinically unsaturated groups. The invention is also directed to a system for storing and delivering Paste (A), Paste (B) and Paste (C), the system comprising three compartments for storing the respective pastes, means for delivering the respective pastes to an outlet orifice and an interface for receiving a mixing tip. The kit of parts or the system is in particular useful for conducting a dental retraction and dental impression process.

A glass-ceramic dental body is provided including three consecutive sections: a section A, a section B, and a section C, wherein each one of the sections has a chemical composition that differs from a chemical composition of the other sections. The glass ceramic-dental body may be characterized by a gradient of a mechanical property, an optical property, and/or a thermal property in a direction from section C to section A. Furthermore, a process is provided for preparing a glass-ceramic dental body and a use of a glass-ceramic dental body.
