Nd: YAG laser

An Nd:YAG laser, often simply referred to as a YAG laser, is a commonly used true pulse laser technology in many medical applications, including in optometry and dentistry. YAG lasers are close to an infrared wavelength of 1064 nm, which can be absorbed by pigment in living tissue, such as melanin and hemoglobin, and have superior biostimulatory properties. Photothermal interaction allows the laser energy to penetrate into the tissues, and the technology can be used as both non-contact and contact depending on the application or procedure being performed. In dentistry, YAG lasers are used primarily for gum disease or periodontal disease to disinfect and debride bacteria-filled periodontal pockets. This technology can also be used to seal treated pockets and support reattachment by acting as a scaffold, as well as for frenectomies, gingivectomies, and biopsies. They can help improve osteogenesis, help with clotting, and can help prevent alveolitis.
