The present invention relates to a dental composition comprising a photoinitiator system comprising a particulate carrier supporting a coinitiator covalently bonded to the surface of the carrier. Furthermore, the present invention relates to a use of the particulate carrier in a dental composition.

The particulate carrier displays multiple covalently bonded tertiary amino groups and/or tertiary phosphine groups on the surface, for crosslinking monomers, oligomers and/or polymers having one or more polymerizable double bonds.

One aspect of the present invention is: a dental glass ionomer cement including a first agent containing an ionomer glass powder; and a second agent containing a polycarboxylic acid polymer and water, wherein the first agent further contains a water-soluble compound represented by general formula (1):

##STR00001##

where R.sup.1 is a hydrogen atom or a methyl group, X.sup.1 is —O— or —NH—, and L.sup.1 is an alkylene group, and a water-soluble compound represented by general formula (2):

##STR00002##

where R.sup.2 is a hydrogen atom or a methyl group, X.sup.2 is —O— or —NH—, L.sup.2 is an alkyleneoxy group, R.sup.3 is an n-valent organic group, m is an integer of 1 or more and 42 or less, and n is an integer of 2 or more and 6 or less.
