Problems solved by technology

[0003] At present, commercialized tooth whitening technologies mainly use light or heating methods such as lasers, light-emitting diodes (LEDs), and plasma arcs as external energy to accelerate the decomposition of hydrogen peroxide. However, ultraviolet light and infrared light are used to promote tooth whitening. While effective, it can cause an excessive increase in temperature in the pulp tissue which can damage the tooth and cause irritation and discomfort
In addition, it is well known that ultraviolet rays can cause certain harm to people's health
Research has found that visible light (400nm-700nm) is a relatively high-quality and safe activation light source at present, but only using visible light as an activation source does not have a good whitening effect

[0048] (1) Apply a whitening agent containing hydrogen peroxide and peroxidase to the tooth surface, wherein the content of hydrogen peroxide is 35wt%;

[0049] (2) Using a compound activation source to activate the whitening agent on the tooth surface for 30 minutes to bleach the teeth when the surface temperature rises to 9°C;

[0050] Among them, the composite activation source includes the application of halogen light, LED light and ultrasonic waves from far to near relative to the whitening agent. The illuminance of halogen light is 200000lux and the wavelength is 650nm; the illuminance of LED light is 6000lux and the wavelength is 463nm. 3000K; the center frequency of ultrasonic is 40KHZ

Embodiment 3

[0052] A method for bleaching teeth, comprising the steps of:

[0053] (1) Apply a whitening agent containing hydrogen peroxide and peroxidase to the tooth surface, wherein the content of hydrogen peroxide is 10wt%;

[0054] (2) Using a compound activation source to activate the whitening agent on the tooth surface for 20 minutes to bleach the teeth when the surface temperature rises to 9°C;

[0055] Among them, the composite activation source includes the superimposed application of halogen light, LED light and ultrasonic waves from far to near relative to the whitening agent. Before irradiating the whitening agent, the ultraviolet rays and temperature in the halogen light are filtered through optical lenses to form cold light. Light source, the cold light source is conducted through the light guide fiber and superimposed with the LED light and ultrasonic waves in turn to form the composite activation source;

Abstract

The invention discloses a method and device for bleaching teeth. The method comprises the steps that (1) a whitening agent containing hydrogen peroxide is applied to the tooth surface; (2) the whitening agent is activated by using a composite activation source, wherein the composite activation source includes superimposed halogen light and ultrasonic waves, the illuminance of the halogen light is170,000 lux-290,000 lux, and the wavelength is 400-650 nm; and the center frequency of the ultrasonic waves is 40+/-1 KHZ. The device is provided with a composite activation source emission part, andthe composite activation source emission part is mainly composed of an LED lamp, a halogen lamp and an ultrasonic generator. According to the method and device for bleaching the teeth, the diffusion rate of hydrogen peroxide through the enamel in vitro can be increased, meanwhile, the bleaching time is effectively shortened, the comfort level of patients in the treatment of teeth whitening is improved, and a good whitening effect is achieved.

Description

technical field [0001] The invention relates to the technical field of teeth whitening, in particular to a method and a device for bleaching teeth. Background technique [0002] Tooth bleaching refers to placing chemical oxidative bleaching drugs on the surface or inside of the teeth, and chemically reacting with the teeth to whiten the color of the teeth themselves. At present, the commonly used bleaching drugs on the market are mainly mixtures containing hydrogen peroxide. During whitening, hydrogen peroxide releases active oxygen or hydroxyl radicals to cleave the coloring molecules containing unsaturated double bonds on the teeth to achieve the bleaching effect. However, because the deep pigment of the teeth is very stubborn and difficult to remove, if the effective peroxide content (in H 2 o 2 If the calculation) does not reach a certain solubility, it is difficult to achieve obvious decolorization or bleaching in a short period of time; moreover, many documents point...
