術者に余分な負担を与える問題点がある。However, this conventional method uses a method of immersing 35 [%] hydrogen peroxide solution in gauze to cover the teeth. Is difficult to keep intimate for a long time, so that there is a problem that the efficiency of bleaching treatment cannot be sufficiently increased in practice, and as a result the treatment time becomes relatively long, which imposes an extra burden on the recipient. There is a problem.
【０００５】本発明は以上の点を考慮してなされたもの

塗布された漂白剤の漂白効率が格段的に大きくなる。According to the method for bleaching vital teeth using the bleaching agent having the above-mentioned constitution, the swelling action of silicic acid anhydride provides an appropriate viscosity such that hydrogen peroxide solution adheres closely to the surface of vital teeth. By being able to obtain the bleaching agent having, the bleaching efficiency of the bleaching agent applied to the tooth surface is remarkably increased.

でき、この分被施術者の負担を軽減できる。Accordingly, the higher the bleaching effect is, the shorter the bleaching time is, and the light irradiation is not always required as in the conventional case, and thus the pulp stimulation caused by the heat of the light irradiation is reduced or eliminated. By doing so, it is possible to prevent tooth pain during or after bleaching, and the burden on the recipient can be reduced by this amount.

できる。In addition to this, the bleaching agent applied to the tooth surface can be washed off by rinsing the oral cavity of the subject with water after the bleaching operation is completed, and the hydrogen peroxide solution in the state applied to the tooth surface Since there is no risk of leaking to the gums,
The protection of the gingiva can be remarkably enhanced as compared with the conventional case, and thus, a bleaching agent which is easy for a practitioner to handle and has high bleaching efficiency can be easily obtained during the bleaching operation.

するような手段を採用できる。In the above-mentioned embodiment, the application of a bleaching agent on the tooth surface was applied using a brush, but the viscosity of the bleaching agent is moderate to high as a means for applying the bleaching agent to the tooth surface. If you prepare it so that it increases to a certain degree, you can apply it by using a spatula, or by filling the cylinder (syringe) with bleach and extruding it on the tooth surface,
The bleaching agent may be filled in the tube container in advance, and the bleaching agent may be directly applied to the tooth surface from the tube container during the bleaching operation.

すれば良い。In the above-mentioned embodiment, the silicic acid anhydride and the hydrogen peroxide solution are mixed and prepared just before the bleaching agent is applied to the tooth surface. Since it has the property of decomposing by light, it is desirable to prepare a mixture just before the treatment. In contrast, when storing the mixed bleach, it is highly airtight and light-shielding. And a stabilizer such as phosphoric acid, barbituric acid, uric acid, acetanilide, oxynoline, and tetrasodium pyrophosphate may be added in an appropriate amount.

者にとつての漂白剤の取扱いを一段と簡便にできる。As described above, according to the present invention, the anhydrous silicic acid is mixed with the anhydrous silicic acid so that the silicic acid anhydride is swollen with the aqueous hydrogen peroxide and has an appropriate viscosity. It is also possible to prepare a bleaching agent that is evenly dispersed without volatilizing hydrogen peroxide water easily. By applying this bleaching agent to the tooth surface, hydrogen peroxide can be applied to the tooth surface of vital teeth. Water can be sufficiently adhered, and thus the bleaching effect of bleaching can be used for bleaching vital teeth. It can be made easier.
