Introduction
This study was carried out to evaluate low power laser effects on incisional wound healing.Materials And Methods
Incisional wound was produced on thirty-six mature male guinea pigs under general and local anesthesia. In half of the animals, He-Ne laser radiations were used for five minutes and the rest of the animals were left untreated. Animals were divided into six groups of six animals each that were killed after 3, 5 and 14 days. After histopathology processing and H&E staining, specimens were examined for acute and chronic inflammations, epithelial cell migration, epithelial seal and barrier formation, fibroblast migration, fibrosis, clot formation and granulation tissue formation. Results
Based on histopathologic results and using, Mann Whitney-U and the Wilcoxon tests statistically significant differences were found between fibroblast migration, acute and chronic inflammation of radiated groups and the control group at 5 day interval.Conclusion
This study showed that He-Ne laser had beneficial effects on incisional wound healing particularly at 5 day-intervals; however, further research on chronic ulcers has been recommended.Language:
