< Topic >At least the monomer of 1 genera and, at least polymerization start system of 1 genera, offer of the constituent for the dentistry barrier which at least includes the indicator of 1 where monitoring of the polymerization reaction is made possible genera.SolutionsThis invention, at least the methacrylate monomer or methacrylic acid derivative monomer of 1 genera and, at least the thickener of 1 genera, regards the constituent for the dentistry barrier which includes with the photochemical start means of polymerization and at least the coloration indicator of 1 genera. In addition, as for this invention, it regards the use of the above-mentioned dentistry barrier in order conservation gearwheel type system and the especially gearwheel pedicle while dealing with at the dentistry barrier, and the dentistry clinic which are obtained the manner which forms the dentistry barrier, with that and during especially ohuisuburichingu dealing with.< Choice figure >Drawing 1【課題】少なくとも1種のモノマーと、少なくとも1種の重合開始系と、重合反応のモニタリングを可能にする少なくとも1種の指示薬を含む歯科バリア用組成物の提供。【解決手段】本発明は、少なくとも1種のメタクリレート系モノマー又はメタクリル酸誘導体モノマーと、少なくとも1種の増粘剤と、重合の光化学的開始手段と、少なくとも1種の呈色指示薬とを含む歯科バリア用組成物に関する。また、本発明は、歯科バリアを形成する方法、それにより得られる歯科バリア、及び、歯科医院での処置中、特にオフィスブリーチング処置中に歯系組織、特に歯茎を保護するための上記歯科バリアの使用に関する。【選択図】図1
