Description

Mobile periodontal disease phototherapy device

The present invention relates to a periodontal disease phototherapy device, and more particularly, to a mobile periodontal disease phototherapy device that is convenient to move and has a separate sterilization function.

As the interest in dental cosmetology has exploded, various kinds of medicines and techniques for teeth whitening have emerged.In addition to conventional whitening silicone molds or vigorous teeth whitening in addition to conventional whitening specialists in dentistry, except for self-healing drugs In recent years, attention has been focused on light whitening.

First, whitening using normal rays is applied to teeth with high concentration of 30% hydrogen peroxide and hot rays such as incandescent lamps or halogens are applied to the teeth for about an hour to whiten teeth. You should go to the dentist for about 6 weeks. To prevent gingival damage, apply gingival aids to the gingival or apply rubber whitening to protect the gingival with a rubber membrane called rubber dam. This method is more effective than the whitening using a silicone mold for whitening, but the disadvantage is that the teeth are much colder, expensive and time-consuming due to heat.

As a result, the so-called blue light whitening method using blue light appeared, but the whitening using the conventional light is hot because the teeth are whitened by using the heat of the normal light, so the tooth is often soaked and more than 3 treatments are performed. On the contrary, the whitening using the blue light does not heat the teeth because it does not have heat, and the effect is high, so the treatment can be finished once or twice. In addition, the concentration of the drug applied to the teeth is also safer because it uses a lower concentration than normal light whitening.

The whitening method using the blue light is divided into the plasma whitening method and the broad blue light whitening method. First, the plasma whitening method is the whitening method using the plasma blue light. You can't whiten all at once. Usually whitening teeth for about 10 minutes to whiten the upper teeth one day, whitening the lower teeth another day. Although it is a very effective whitening method, it is disadvantageous in that the equipment is expensive and it takes a long time and the treatment cost is high.

On the other hand, the wide blue light whitening method is the most effective whitening method to compensate for the shortcomings of the plasma whitening is a whitening method that can whiten all teeth at once because the blue light shines a large area. Most recently developed, whitening is usually accomplished by shining a beam for 30 minutes to an hour. The principle of the broad blue light whitening method is to prepare a whitening paste in the form of a gel containing a photoactive agent reacting with blue light around 470 nm in a bleaching component such as hydrogen peroxide and applying it to the teeth to be whitened. The whitening of the teeth is achieved by irradiating blue light of the above wavelengths and activating the bleaching agent by the photoactive agent.

Fig. 1 shows an example of a conventional light source device used for such widening blue light whitening. In FIG. 1, light generated from a light source 101 such as a halogen lamp or a xenon lamp is concentrated to the front through the reflector 102 and only a blue light beam is transmitted through the blue filter 103, and then a beam spot Formed through the molded part 104 is irradiated to the teeth (T) of the patient to be whitened. The beam spot forming unit 104 forms a circular radiation beam into a rectangular beam spot to irradiate several teeth T of the patient at the same time. In this example, the beam spot forming unit 104 is formed of an optical fiber bundle. It is configured, but it can play the same role as a lens and a shutter. In addition, a light source device without the beam spot forming part 104 is also used by using a light source in which LEDs are arranged in a rectangular array. And a cooling fan 105 for cooling may also be additionally provided.

However, the whitening method using the light source device as described above has a problem in that the light output is weak, the treatment range is limited, and the treatment effect is not large.
