摘要：
The present invention features a hardenable dental composition that contains: (1) at least one cyclic allylic compound having at least one sulfur atom in the ring, and (2) at least one at least one ethylenically unsaturated compound, such as a substituted (meth)acryloyl compound. The compositions also typically comprise an initiator system, preferably a photoinitator system containing at least 0.08 wt-% of one or more photosensitizers.
