    摘要： In a first aspect, a method for treating hard tissue that includes: (a) applying to hard tissue a composition that includes a cationically active functional group, a free radically active functional group, and a polymerization initiator capable of initiating free radical polymerization, where the number of moles of cationically active functional groups per gram of composition is no greater than about 0.0075; and (b) exposing the composition to polymerization conditions to form an adhesive bonded to the hard tissue.In a second aspect, a method for treating hard tissue that includes: (a) applying to hard tissue a first polymerizable composition that includes a free radically active functional group and a polymerization initiator capable of initiating free radical polymerization, but is essentially free of polymerizable components having cationically active functional groups and is capable of forming an adhesive bonded to the hard tissue upon exposure to polymerization conditions; (b) applying a second polymerizable composition; and (c) exposing the second composition to polymerization conditions to form a hardened composition adhered to the hard tissue. The second composition includes (i) a cationically active functional group and (ii) an polymerization initiator capable of initiating cationic polymerization.

    摘要： Disclosed is a packaged element containing a) a substrate that transmits less than about 0.5% of actinic radiation and has at least one recess, b) a cover that transmits less than about 0.5% of actinic radiation and transmits at least part of the visible light spectrum, c) a structure for maintaining the cover in contact with the substrate such that the cover filters incident radiation entering the recess, and d) an element located in the recess and having a substance thereon that is curable by exposure to the actinic radiation. Also disclosed is an article containing a) a substrate having at least one recess with an interior surface, b) an element having a tacky substance on a surface thereof, and c) a structure for positioning the element inside the recess such that the tacky substance does not separate from the element upon removal from the recess.
