Zusammenfassung: | The invention relates to a two-part dual cure dental composition with improved stability toward discoloration and premature polymerization. The dental composition comprises a Base Part and a Catalyst Part, the Base Part comprising polymerizable component(s) without an acidic moiety, optionally polymerizable component(s) with an acidic moiety, filler(s), transition metal component(s), peroxide component(s), stabilizer component(s) comprising a free-radical moiety, the Catalyst Part comprising polymerizable component(s) without an acidic moiety, filler(s), ascorbic acid component, photo-initiator system, stabilizer component(s) comprising a phosphite or sulfite moiety. The dental composition is in particular useful as bulk fill dental composite, dental resin cement, core build-up dental material or self- and dual cure dental adhesive. The invention further relates to an initiator system and the use of a stabilizer comprising a free-radical moiety.
