The invention discloses a preparation method and application of polyethylene glycol functionalized nano capsule-like gel. The preparation method comprises the following steps: (1) extracting a nano capsule-like body; (2) preparing polyethylene glycol functionalized nano capsule-like gel; and (3) applying the polyethylene glycol functionalized nano capsule-like gel to mediating photodynamic tooth bleaching. The polyethylene glycol functionalized nano capsule-like gel is combined with a photodynamic reaction to interfere with an electron transport chain and promote ROS accumulation, and the nano capsule-like gel with a specific photoreaction oxidation function is constructed, so that the nano capsule-like gel can be used for equivalently bleaching teeth with a traditional bleaching agent, and meanwhile, the activity of the nano capsule-like gel is improved. The sensitive risk to tooth essence and the mechanical injury risk to enamel and cementum are remarkably reduced, and the composition can be applied to home care or clinical whitening treatment; and the preparation method is simple, is convenient to use, is mild and non-irritant, is high in biocompatibility, and has a good market application prospect.

The utility model relates to the field of oral irrigators, in particular to an ozone ion generating device for an oral irrigator and the oral irrigator. The shell is installed in a water tank in the oral irrigator, an opening is formed in the top of the shell and communicated with a power assembly in the oral irrigator, the ozone generator is installed on the lower portion of the shell and electrically connected with the power assembly outside the water tank through the opening in the top of the shell, and a release hole is formed in the bottom of the shell. Ozone ions generated by the ozone generator enter the water tank through the release hole; a sealing device is arranged on the shell and used for isolating water entering the shell through the release hole from the opening. By means of the mode, the ozone water and the hydrogen-rich water can be generated in the water tank of the oral irrigator, bacteria and viruses in teeth and the oral cavity can be rapidly and effectively killed, halitosis can be removed, and the effects of bleaching teeth and removing dirt are achieved.

There is herein described a teeth whitening strip or film. In particular, the present invention relates to a dissolvable or substantially dissolvable hydrogen peroxide (H2O2) teeth whitening strip or film comprising a concentration of hydrogen peroxide (H2O2) at or above 10 wt. % of the strip or film. There is also described a process for the manufacture of a dissolvable or substantially dissolvable tooth whitening strip or film along with the method of using a strip or film comprising a concentration of hydrogen peroxide (H2O2) at or above 10 wt. % of the strip or film to whiten and / or bleach teeth.

The invention relates to a mouthwash self-making machine which comprises a machine shell, a control part and a water outlet, the control part and the water outlet are arranged on the machine shell, an ozone generating device, a first water tank, a second water tank, a first water pump and a second water pump are arranged in the machine shell, and the ozone generating device is arranged at the bottom in the second water tank; the first water pump is connected with the first water tank and the second water tank, and the second water pump is connected with the second water tank and the water outlet; the capacity of the first water tank is larger than that of the second water tank; a cup stand is arranged at the bottom of the machine shell, an NFC recognition module is arranged in the cup stand, and the NFC recognition module, the ozone generation device, the first water pump and the second water pump are in signal connection with the control part. The invention aims to provide a mouthwash self-making machine. The mouthwash produced by the machine has the effects of removing bad breath of a user, bleaching teeth and killing oral bacteria.

The application discloses a method and device for bleaching teeth, the method is: (1) applying a whitening agent containing hydrogen peroxide to the surface of teeth; (2) activating the whitening agent by using a composite activation source; wherein the composite activation source comprises superimposed applied halogen light and ultrasonic waves, the halogen light has an illuminance of 170000 lux-290000 lux and a wavelength of 400-650 nm; the center frequency of the ultrasonic waves is 40+ / -1 KHZ. The device has a composite activation source emitting part, which is mainly composed of an LED lamp, a halogen lamp and an ultrasonic wave generator. The application can accelerate the external diffusion rate of hydrogen peroxide through tooth enamel, effectively shorten the bleaching time, improve the comfort of patients in tooth whitening treatment and has a good whitening effect.
