Embodiment 1

[0054] The making of the ivory plate

[0055] The surface of an ivory disc (circular, about 1.5 cm in diameter, about 3 mm in thickness) sold in the general market is polished with No. 60 (coarse mesh) sandpaper to make the disc surface smooth. The brightness of the surface of the polished ivory plate was measured with Shade Up Navi (a colorimeter for tooth surface bleaching, manufactured by Matsukaze Co., Ltd.), and it was confirmed that the color tone (brightness) of the polished surface was 1. The ivory plate was in the test. use. The brightness value shown in Shade Up Navi is from 1 to 9, and it increases with every 0.5 as a scale value. Hue 1 is the brightest, and the brightness decreases as the value increases.

[0056] Preparation of various solutions used in coloring operations

[0057] Various solutions for use in the coloring operation were prepared in the following manner. First, 1% by weight of IXOS SCP5000 (manufactured by Nitta Gelatin Co., Ltd.) was diss...

Embodiment 2

[0084] Preparation of dried hydroxyapatite with tea stains

[0085] First, prepare protein solution (1% by weight of EquosSCP5000, manufactured by Xintian Gelatin), tea stain, artificial saliva (20mM HEPES KOH (pH7.0), 1.5mM CaCl 2 , 0.9mM KH 2 PO 4 ).

[0086] Tea stains are made in the following ways. Put 5g of instant coffee, 2 black tea bags, and 2 green tea bags into 110ml of water, heat in a microwave oven for 2 minutes, then shake at room temperature for 3 hours to overnight to release heat. Next, the solution was filtered through 200-mesh filter paper.

[0087] Dry hydroxyapatite with tea stains was produced in the following manner. Put 2.5 g of hydroxyapatite powder (Biogel-HTP, manufactured by BioRad) into a 50 mL test tube, add 20 mL of protein solution, let stand for 15 minutes, perform centrifugation (2500×G, 2 minutes), and remove the supernatant . Thereafter, 20 mL of tea-stained liquid was added to the hydroxyapatite precipitated after centrifugation, ...

Abstract

[Problem] The purpose of the present invention is to provide an oral composition that enables a high level of whitening effectiveness to be obtained over the entire application area of the oral composition. [Solution] The present inventors discovered that a tooth whitening composition with a high level of whitening effectiveness over the entire tooth whitening composition application area can be obtained by including colloidal platinum as a platinum catalyst in a peroxide-containing oral composition. The present inventors also discovered that whitening effectiveness can be enhanced by application of a tooth whitening composition comprising colloidal platinum to the surface of the teeth followed by photo-irradiation of the application site.

Description

technical field [0001] The invention relates to a tooth bleaching composition containing platinum nano colloid. Background technique [0002] The tooth surface is stained by staining source substances such as coffee, tea, and tobacco tar. Removing coloring stains on the tooth surface and keeping the teeth white have been long-standing goals of dental care, and various products for whitening the tooth surface have also been developed. In addition, dentists also perform treatments for whitening the surface of teeth. [0003] Oral compositions containing peroxides are generally used to whiten tooth surfaces. It is known in the prior art that peroxides exert their bleaching effect on teeth by decomposition. Peroxides are decomposed by metal catalysts such as titanium dioxide to exert their bleaching effect. As described above, oral compositions containing both peroxides and metal catalysts are used for tooth bleaching. [0004] Patent Document 1 discloses a tooth bleaching ...
