Irradiation effect of 780-805nm diode laser on wound healing in mice
Main Article Content
Abstract
Material and methods: The experimental study was performed on ninety six white albino mice. An incision of 1.5cm length was done on the face side of each mouse. Then the animals were divided into two main groups; control group which didn’t receive laser irradiation while the other group was the lased group which exposed to single dose of 360J/cm of 780-805nm diode laser. Animals were subdivided into four subgroups according to healing periods. Histological specimens were taken at 1st, 3rd, 7th and 14th day for microscopical examination concerning inflammatory cells infiltration and epithelial cell layer thickness.
Results: Results show obvious reduction in inflammatory cell infiltration and more epithelization in laser treated wounds compared with control wounds. Statistical analysis showed a significant difference between two groups.
Conclusion: Low level diode laser (790-805nm) has beneficial effects in enhancement of soft tissue wound healing process histologically.
