ABSTRACT:
The invention features compositions comprising at least one monomer that comprises a cyclic dithiane moiety attached to a (meth)acryloyl moiety. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.
