Taking a new approach – the 445-nm laser in clinical applications

Laser systems are used in a variety of dental treatments, particularly in the fields of surgery, restorative dentistry, endodontics, and periodontology, in order to improve both the patient´s comfort and the treatment result. The effectiveness of the laser crucially depends on how the tissue absorbs the electromagnetic radiation. The development of a new kind of diode laser in the blue wavelenght range (445nm) promises good energy coupling to pigmented cells and tissue. Combined with low absorption in water, the cutting performance for surgical procedures is superior to conventional semiconductor lasers in the wavelength range 810 to 980 nm. Furthermore, blue laser light is an ideal way to improve standard methods of bacterial reduction in periodontal lesions and root canals. This overview illustrates and discussed the clicnical applications with the new 445-nm laser technology, as well as current study results. The range of applications of the blue light laser is presented here based on clinical cases.
