A redox curing dental composition comprising:(a) one or more compounds having a radical polymerizable carbon-carbon double bond;(b) a redox initiator system comprising(i) a reducing agent which is a compound of the following formula (I):whereinR1and R2which may be the same or different, independently represent a C1-18hydrocarbyl group, or R1and R2form together with the silicon atom to which they are bonded a 3 to 8-membered silicon-containing alicyclic ring, which groups R1and/or R2may be substituted with one to three substituents selected from the group consisting of a C1-6alkoxy group, a halogen atom, or a carboxylic acid group; and(ii) an oxidizing agent adapted to oxidize the reducing agent of formula (I) in the absence of light for generating a radical capable of initiating radical polymerization of the one or more compounds having a radical polymerizable carbon-carbon double bond.
