Abstract
A composition for use in dental treatments of damaged or diseased teeth is provided. The composition comprises a combined filler material, photoinitiator and comonomer resin mixture polymerizable upon incidence of light. The comonomer resin mixture comprises a comonomer resin blend comprising at least two monomers from the same monomer series with at least a first monomer having a first molecular weight and a second monomer having a second molecular weight with the second molecular weight being greater than the first molecular weight of the first monomer. The comonomer resin mixture further comprises a third monomer combined with the comonomer resin blend.
