Abstract
Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.
