Description

Laser irradiation device for oral treatment {LASER IRRADIATION DEVICE FOR ORAL TREATMENT}

The present invention relates to a laser irradiation device for oral treatment having a new mouthpiece structure to facilitate laser treatment of areas in the oral cavity vulnerable to oral mucositis.

In general, low-level laser therapy (LLLT) is a treatment method that promotes a spontaneous healing effect on damaged areas of the body through a photobioregulation mechanism that regulates biological activity using laser light. LLLT technology is used in various fields such as skin and beauty, ophthalmology, dentistry, pain relief, wound treatment, neurology, and oncology. In particular, in dentistry, laser irradiation devices are used to whiten teeth, relieve oral pain, and treat oral mucositis.

Meanwhile, there are frequent cases of patients with moderate to severe oral mucositis occurring after anti-cancer radiation treatment or chemotherapy. Recently, many papers have reported results showing anti-inflammatory effects such as wound healing, collagen synthesis, and neutrophil reduction after testing low-power laser treatment on animal models that induced oral mucositis.

Republic of Korea Patent Publication No. 10-2013-0057692 “Mouthpiece for oral treatment and oral treatment device having the same” and Registered Patent No. 10-1554721 “Oral light irradiation device” are applied to the inside of the mouth while the patient is holding the mouthpiece. A treatment device that uniformly irradiates a laser beam is being proposed. However, the above prior literature is configured to spread the laser beam using a beam expander and deliver it into the oral cavity or to transmit the laser light into the oral cavity by light reflection using a reflection unit, so the intensity of the laser light is weak and the laser is applied to the inflamed area. There was a problem in that the energy was weakened in the process of reaching it, making it difficult to cause damage to living organisms.

Typically, the areas where oral mucositis frequently occurs after anticancer treatment are vulnerable areas in the oral cavity, such as the oral vestibule, periodontium, sublingual glands, and tonsils. While these vulnerable areas are located deep within the oral cavity, in the above prior art, they are located in the front part of the oral cavity. There were limitations in treating oral mucositis due to structural problems where the amount of light was concentrated and it was difficult for the light to reach vulnerable areas with high intensity. In addition, the above prior art irradiates light with a single wavelength, but there is a problem in that the light cannot penetrate deep into the desired area as the energy is dissipated in the process of penetrating into the living body.
