However, the same study showed that only P. gingivalis strains were susceptible to this phototoxicity while in biofilm state. The authors' conclusion was that the dental halogen curing light was “effective in reducing periodontal pathogens in planktonic state” 2 and that this method could be used for the treatment of periodontal disease.
E. coli is a type of fecal coliform bacteria commonly found in the intestines of animals and humans. A positive E. coli result is much more serious than coliform bacteria alone because it indicates that human or animal waste is entering the water supply. There are hundreds of strains of E. coli.The blue light acne treatment light also does not cause tanning or skin burn. Studies have also found that using blue light therapy for 3 consecutive days has been shown to reduce bacteria in the pores by up to 99.9% with up to 80% of patients showing an overall improvement over 3 months, although 10% of patients did not find any improvement at NIR light heals by ensuring that cytochrome oxidase binds with oxygen to turn on protectors and stimulate cell metabolism. Blue light, on the other hand, causes a toxic environment when the immune response has been triggered. That poisonous effect hastens healing of topical wounds by killing bacteria that cause infection.
For these PS, blue light (400 to 480 nm) is more effective at a microbial inactivation than green (480 to 550 nm) or red (600 to 700 nm) light. The blue light of shorter wavelength (400 to 450 nm) is more phototoxic compared to that of the blue light’s longer wavelength. Although red light is not as effective as blue light, it can be more6Q8dxeb.
