    Abstract: 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.

    Abstract: The invention relates to a composition for isolating tissue, the composition comprising a radiation curable component A1, preferably being present in an amount of at least 40 wt. % with respect to the composition, the radiation curable component A1 comprising a polyether polyol spacer group having a molecular weight (Mw) of 1,000 to 20,000 g/mol, and at least two (meth)acrylate moieties, photo-initiator, guanidyl containing polymer, carrageenan, optionally softener, optionally dye, optionally filler, optionally additives. The invention also relates to a process for temporarily isolating tissue, the process comprising the steps of providing the composition described in any of the preceding claims, placing the composition in contact with tissue, radiation curing the composition at least partially for a time period T1, optionally moving or adjusting the partially cured composition, optionally radiation curing the partially cured composition for a time period T2, wherein T2>T1, removing the composition from the tissue.
