A dental restorative composition comprises about 35 to about 43 wt %, based on the total dental restorative composition, of a polymerizable, ethylenically unsaturated resin composition, wherein the resin composition comprises, based on the resin composition alone, about 25 to about 35 wt % PCDMA, about 40 to about 50 wt % EBP-DMA, about 18 to about 28 wt % Bis-GMA, and about 55 to about 70 wt %, based on the total dental restorative composition, of a filler system, wherein the filler system comprises a silanized barium glass containing about 20 to about 60 wt % barium oxide based on the weight of silanized barium glass. Such dental restorative compositions display an ability to flow under ambient conditions and this increases their utility where improved flexural strength and ease of application is desired.
