| Outline of Final Research Achievements |
For the treatment of anti-resorptive agents-related osteonecrosis of the jaw, Low reactive Level Laser Therapy is indicated overseas than before. In recent years, Low reactive Level Laser Therapy has been recognized as Low reactive Level Light Therapy including light sources such as LEDs in addition to lasers, and this research was started to find out the effectiveness of LED light for anti-resorptive agents-related osteonecrosis.
The effect of LED irradiation on the indigenous bacteria in the cultured oral cavity was analyzed. Streptococcus salivarius was irradiated at wavelengths of 405, 630, and 950 nm, and the number of viable bacteria in the LED-irradiated group and the LED-non-irradiated group (control group) was compared, and a decrease in the viable cell count in the LED-irradiated group was observed.

| Academic Significance and Societal Importance of the Research Achievements |
培養口腔内常在菌に対するLED照射効果は、Streptococcus salivariusにおいて405、630、950nmのいずれの波長でも生菌数の減少を認めた。
LED光のARONJに対する有効性を見出し、レーザーよりも安価で簡便なLEDによる新規のARONJ治療機器開発へつなげる可能性が示唆された。
