Abstract: Provided are monomers useful for dental materials that include a compound in which a core and a specific terminal group are bonded to each other directly or via a linking group, wherein the core is a C1-200 polyvalent organic group having a valence of not less than 3 containing an oxygen atom or a nitrogen atom in which an atom bonded to the terminal group or the linking group is the oxygen atom or the nitrogen atom; the terminal group is a specific (meth)acryloyl group-containing group, a (meth)acryloyl group, a C1-20 hydrocarbon group or a hydrogen atom, and the terminal group needs to meet specific requirements; and the linking group is a specific divalent group, and when the compound contains a plurality of linking groups, the linking groups may be the same as or different from each other. Compositions, dental materials and kits are also provided.
