To allow the restoration of a tooth to be performed with satisfactory color tone conformability and little reduction in lightness, thus enabling restoration with high aesthetics, in particular, to allow even the characteristic structure of dentin to be reproduced even in a cavity in which a background color tone can be seen through, provided is a dental filling and restorative material kit, including: a polymerizable composition (A) for a dentin restorative material for restoring a dentin portion; and a polymerizable composition (B) for an enamel restorative material to be layered on the dentin restorative material, in which the polymerizable composition (A) for a dentin restorative material and the polymerizable composition (B) for an enamel restorative material have different color tones, and in which a difference (n D a -n D b ) between a refractive index n D 3 of a polymer of a polymerizable monomer (a) in the polymerizable composition (A) for a dentin restorative material and a refractive index n D b of a polymer of a polymerizable monomer (b) in the polymerizable composition (B) for an enamel restorative material is 0.005 or more. |
