Also to design our own opinion on the subject, as chemists. Laser is nothing more than a light with very special characteristics that grant it therapeutic properties. We can observe the existence of three different types of laser, being one of them the therapeutic laser, which is used in substitution for medications or along with them. Another type of laser is the surgical one and, in addition to these, there is a diagnostic type. A great advantage is that, instead of taking the medicine, the patient’s own body can be activated by the laser to produce certain substances that can often replace the drugs. This is a literature review emphasizing the use of low level laser. Thus, the reflections from this study can contribute to the amplification of the production of knowledge that aims at the resignification of the use of laser in therapy. Greater attention was given to two types of laser radiation: He-Ne and As-Ga, both presenting a high therapeutic potential in superficial and deep injures. However, the He-Ne laser excels in superficial lesions, whereas the As-Ga laser does so in deep injures, such as articular, muscular, etc.展开更多
