BACKGROUND -Several studies have been performed to understand the tissue repair process as well as the possible effects of laser therapy in wound healing. OBJECTIVES -To study the behavior of skin wounds induced in the dorsal region of Wistar rats (Rattus norvegicus), which were submitted to the low-intensity laser therapy at 3.8 J/cm 2 dosage, 15mW potency, during 15 seconds. MATERIAL AND METHODS -The animals (n=12) were divided into two groups -control and laser-treated. The latter comprised three applications (immediately after surgery, 48 hours and 7 days after induction of surgical wounds). Ten days after surgery samples of the wounds were collected and submitted to histopathological and histomorphometric studies. RESULTS -Neovascularization, fibroblast proliferation and reduced inflammatory infiltrate in surgical wound submitted to laser therapy were demonstrated. CONCLUSION -Taken together, the results suggest that low-intensity laser therapy is an effective method to modulate tissue repair, thus significantly contributing to a faster and more organized healing process.
