Study of the strength of healing skin of rats treated with phototherapy in laser
Introduction: Laser therapy has been widely studied for its healing; however, few studies have been developed to evaluate tensile strength after phototherapy.

| Sumario: | Introduction: Laser therapy has been widely studied for its healing; however, few studies have been developed to evaluate tensile strength after phototherapy. Objective: To analyze voltage scar skin incisions in rats after laser therapy (InGaAlP-670nm). Method: Twenty rats were divided into two groups (placebo/irradiated), underwent skin incision on the back. The irradiated group received a dose of 6J/cm2 and in the placebo group the equipment remained off. After sacrifice, three and seven days post-surgery, skin samples were subjected to tensile-histological analysis. Results: It was observed significant difference in breaking strength between groups, decrease in maximum deflection (without statistical expression), reduction of the inflammatory infiltrate and acceleration of fibroplasia and angiogenesis, consistent with increased synthesis of collagen in the area of lesions in the irradiated group. Conclusion: Therapy with low-intensity laser increases the tensile strength of the skin, enhancing tissue repair response, reducing risks of dehiscence and postoperative complications. |
