REDOX CURING DENTAL COMPOSITION

A redox curing dental composition comprising:a. one or more compounds having a radical polymerizable carbon-carbon double bond;b. a redox initiator system comprisinga reducing agent which is a compound of the following formula (I):whereinR1 and R2which may be the same or different, independently represent a C1-18 hydrocarbyl group, or R1 and R2 form together with the silicon atom to which they are bonded a 3 to 8-membered silicon-containing alicyclic ring, which groups R1 and/or R2 may be substituted with one to three substituents selected from the group consisting of a C1-6 alkoxy 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.
