Of the different physiotherapy techniques used in the nervous process repair, the use of Low level laser therapy (LLLT) has generated results, due to the biostimulant effects that generates laser irradiation while interacting with tissues and cells. This study seeks to identify changes or morphological microscopic alterations of inferior alveolar nerve in healthy rats. We used 16 Sprague Dawley rats, which were exposed to Low level Laser in the side area of the mandibule. The left side was taken as a control on the right side was applied low-level laser so transcutaneous for 1 minute with a power density of 5 Joules/cm2, 3 sessions per week, a total of 3 weeks. The sample unit and the histological analyses were obtained from the inferior alveolar nerve section and its surrounding tissue. The results show that there is a noticeable difference in the thickness of perineural tissue in irradiated side compared to the control side, the average thickness was 21.125 mm in irradiated group and 27.575 mm for the control group showing a statistically difference significant between them. In conclusion, the application of low-power laser at low dose produces a variation in the nervous morphology, increasing the density of its components.
KEY WORDS: Low level laser therapy, laser biostimulation, inferior alveolar nerve.
