Abstract
Official abstract text for this publication.
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 a 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.
First claim
Opening claim text (preview).
1 . A dental filling and restorative material kit, comprising: 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, wherein the polymerizable composition (A) for a dentin restorative material and the polymerizable composition (B) for an enamel restorative material have different color tones, and wherein a difference (n D a -n D b ) between a refractive index n D a 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. 2 . A dental filling and restorative material kit according to claim 1 , wherein the dental filling and restorative material kit consists of the polymerizable composition (A) for a dentin restorative material and the polymerizable composition (B) for an enamel restorative material. 3 . A dental filling and restorative material kit according to claim 1 , wherein a 1-mm cured body of the polymerizable composition (A) for a dentin restorative material has a contrast ratio of from 0.55 to 0.75, and wherein a 1-mm cured body of the polymerizable composition (B) for an enamel restorative material has a contrast ratio of from 0.30 to 0.54.
