Description

  The present invention relates to tooth whitening in which teeth are decolored by irradiating the teeth with light, and more particularly to teeth whitening in which a liquid drug in which a photocatalyst is dispersed is applied to the teeth and irradiated with light.

Conventionally, for example, a color or stain of a tooth may occur due to a pigment or dirt of a drink such as cigarette, coffee or colored soft drink, or food such as curry being attached to the tooth. In such a case, from the aesthetic point of view, there is a high need for tooth whitening, particularly for young women, to whiten teeth or return the color of teeth to the original color.

With regard to the whitening of the teeth, for example, the mouth is opened with an opening tool or the like, and a drug in which a photocatalyst such as titanium oxide is dispersed is applied to the tooth surface. A technique for decomposing is known. There are various types of drugs such as liquid, gel or paste. In the case of a gel or paste, it is known that the photocatalyst contained in the drug is less likely to adhere to the tooth surface compared to a liquid drug, so that the decomposition reaction is difficult to proceed even when irradiated with light. .

Various proposals have been made regarding tooth whitening using such drugs and light (see, for example, Patent Document 1).

JP 2000-217844 A

According to Patent Document 1, a dental light irradiating device for performing decolorization or treatment of teeth by light irradiation, which has a substrate on which a plurality of light emitting diodes are arranged on a curved surface, the substrate inside, and teeth on the front surface. A light source device having a shape along the row and having a light-transmitting surface that irradiates light on the front surface of the dentition, and a positional relationship in which the light source device is disposed at the tip and the light source device is opposed to the dentition of the therapist And a posture positioning mechanism that can determine the posture and position, and a technique for decoloring teeth by irradiating light from a light source device onto a dentition coated with a photocatalyst is disclosed.

The inventor of the present application has accumulated research on applying a liquid drug containing a photocatalyst to the tooth surface and attempting to whiten the teeth by irradiating the drug with light. The inventor of the present application said that even if the drug is irradiated with light, if the drug remains wet, the catalytic reaction does not proceed immediately, for example, after about 7 to 10 minutes have elapsed. I found it.

If it does so, according to the light source device of patent document 1, a user may be forced to apply the state which opened the mouth, for example, apply | coating a liquid chemical | medical agent to a tooth surface, and light irradiation is completed for about 7 to 10 minutes. There is. However, when about 3 to 4 minutes have passed after the mouth is opened with a drug or the like applied to the teeth, there is a problem that saliva accumulates in the mouth and user discomfort increases.

Therefore, the present invention has been made in view of the above-described conventional problems, and the purpose of the present invention is to enable tooth whitening in a short time even with a liquid medicine, and to reduce tooth discomfort for the user. It is to provide a whitening device.
