In general, the global dental medical device market is growing at a rate of 4.2% every year. In particular, the emerging markets are growing much higher due to the government-led medical infrastructure expansion policy than the dental market of advanced countries.

The Chinese dental medical device market is also recording high growth every year.The Chinese dental medical device market is expected to grow at a CAGR of 19% by 2019, and the implant penetration rate in China is 2 people per 10,000 people, and Korea (250 per 10,000 people) It is 1% of people).

In the future, the size of the global dental market is expected to be $18.8 billion in 2015 and $20.8 billion in 17, with an average growth of 5.1%.

Among these dental medical devices, especially in dental devices using LEDs, the majority of teeth whitening devices for a whitening effect of teeth are mainly concentrated on these teeth whitening devices. Therefore, devices released for physical therapy along with physical management of gums including teeth are not yet widely distributed.

Of course, dentistry is also introducing the concept of physical therapy for gums including teeth, but physical therapy in dentistry has long been limited to the treatment of patients with oral and facial pain and jaw joint disorders.

However, in recent years, many dentists are conducting research on physical treatment methods to reduce the burden on patients and increase the efficiency of treatment of gums including teeth, and interest in related devices is increasing.

In response to this interest, some of the dental physical therapy devices are sometimes released on the market, but once these dental physical therapy devices fail, users cannot understand the cause of the breakdown, and It is also experiencing difficulties in replacement or maintenance of consumables.

When the dental physical therapy device breaks down or the consumable needs to be replaced, it is common for the product of the dental physical therapy device to be left unused due to difficulty in taking measures or repairs A/S. In particular, it is more difficult to maintain dental physical therapy devices in public places or in general homes. Accordingly, when a failure or replacement of consumables for such a dental physical therapy device arrives, a function and service that informs the timing of this in advance is also required.

Moreover, conventional lamps applied to dental physical therapy devices treated by light irradiation contain mercury when irradiating a light source, and their use is restricted or prohibited due to environmental remedies, and due to the short service life of the lamp. The replacement cost due to frequent replacement of the lamp is also incurred.

E. coli cultured in the liquid medium was plated on the E. coli plate medium, and a 405 nm wavelength was applied to the plate medium on which E. coli was smeared with an intensity of 40 nW, 10 J/cm ² , 20 J/cm ² , 30 J/cm ² , 50 J/cm ² , and the solid medium was cultured in an incubator at 37° C. for 24 hours, and then CFU (Colony Forming Unit) can be measured.

It can be seen that a light source in a specific wavelength range is effective in sterilizing E. coli at 405 nm. However, as calibration equipment cannot be used to measure the optical characteristics of a sample for cell experiments, additional experiments may be required to secure the reliability of light source data and to develop a light source with optimal sterilization optical characteristics.

As a result of cell regeneration experiments of osteoblasts and hair follicle cells using LED light wavelength, the regeneration effect of normal cells can be confirmed through LED light irradiation with wavelengths of 630nm and 850nm.

Of course, the amount of light irradiation that evaluates the medical performance of an LED light source for skin irradiation can generally analyze the value of radiant energy per area, and a portable illuminometer type equipment is commonly used to evaluate the electro-optical characteristics of the LED light source. A measurement error of more than 20% may occur. Therefore, in order to accurately calculate radiant energy [J/cm ² ], it is essential to use a special wavelength light distribution measuring device. In addition, it is appropriate that expert manpower analysis support for the measured data should be required.

In the LED light source irradiated from the light irradiation module unit 300, the LED required for cell regeneration and pain relief recognizes the importance of light output and emission wavelength (center wavelength, peak wavelength), and analyzes the characteristics of light sources with excellent sterilization power. Can be reflected.
