First, to prepare a plasma intensifying member, a tip was cut out from a tip of a butterfly used for dental treatment as shown in FIG. 21, and a gel type hydrogen peroxide (H ₂ O ₂ ) of 5.4% concentration was injected into the tip as an enhancer.

Thereafter, as shown in FIG. 22, a tip into which hydrogen peroxide was injected was attached to a nozzle of a plasma generator, and a plasma generator was operated as shown in FIG. 23 to spray a plasma on a Petri dish cultured with a typical cucumber germ, S. mutans .

In the comparative example of the present invention, only the tip of the butterfly with the cut-off end was attached to the nozzle of the plasma generator, and the plasma was sprayed to the petri dish cultured with mutans.

24 is an image for checking the sterilizing effect of the plasma according to the comparative example in which only the tip is mounted on the nozzle of the plasma generator and the embodiment in which the hydrogen-peroxide-injected tip is mounted.

The comparative sample in which the plasma was sprayed to the Petri dishes in which the bacteria were cultivated with only the tips attached to the nozzles was observed as a prototype with a diameter of about 0.2 cm, about 0.7 cm, and about 0.9 cm after 15, 30, Bacteria were killed as much as the area.

On the other hand, the samples of the example in which the hydrogen peroxide-impregnated plasma was sprayed with the hydrogen peroxide-impregnated tip in the nozzle had a diameter of about 1.8 cm, about 2.8 cm, and about 4.4 cm after 15, 30, The bacteria were killed by the circular region with.

As a result of the sterilization test, when sterilization was proceeded by spraying a plasma containing hydrogen peroxide by using the plasma intensifying member of the present invention, sterilization effect was remarkable not only in the size of the sterilization zone but also in the sterilization rate, As shown in Fig.

In addition, as described above, a tooth whitening experiment was conducted by spraying a plasma to a tooth after attaching a tip into which the hydrogen peroxide was injected to the nozzle of the plasma generator. Similarly, as a comparative example, plasma was sprayed without attaching a tip to observe degree of tooth whitening.

In the tooth whitening test, 50 teeth were used in the comparative example and the example, respectively, and the plasma spraying time was 20 minutes.

In order to analyze the whitening degree of the teeth, the teeth were photographed using a stereoscopic microscope in a darkroom condition before and after the whitening treatment, and then the average of the brightness obtained in various parts of the tooth image was obtained using Photoshop, an image processing program, , And the amount of change ΔE in brightness of the teeth before and after the whitening treatment was calculated.

As a result of the experiment, in the comparative example, the average of the brightness change amounts DELTA E of 50 teeth was 2.61, and the average brightness change amount DELTA E of the 50 teeth in the example was 7.64, which was 2.93 times that of the comparative example.

Fig. 25 is an image before and after a whitening treatment of two teeth (teeth 1 and 2) subjected to a whitening treatment according to a comparative example, and Fig. 26 is an image before and after a whitening treatment of two teeth (teeth 3 and 4) It is a later image.

The amount of change in the brightness DELTA E of the teeth 1 to 4 according to the comparative example and the example is as follows.

teeth The amount of change in brightness (DELTA E) Comparative Example One 2.62 2 2.60 Example 3 7.66 4 7.62

As a result of the whitening test, it was confirmed that the plasma of the plasma intensifying member of the present invention was used to spray a plasma containing hydrogen peroxide to increase the brightness of the teeth of the comparative example, which was simply whitened by plasma spraying. In other words, when the teeth of the present invention are whitened using the plasma intensifying member, the whitening enhancement effect of about three times as much as that of simply whitening the teeth with plasma alone can be achieved.
