Abstract:
This study tries to show an approach for wound healing process based on using of low level laser therapy, in order to enhance the healing rate of wounds. The low power lasers (LPL) was introduced to solve different pattern recognition problems associated with scar formation after completing of healing process. The research shows that LLLT can be trained to solve these problems efficiently.The work in this study describes the enhancement of healing process rate by using low power diode laser therapy.The skin and its histological description, wounds and their types, the healing process phases, and the laser systems that are used in the therapy were describe in the present work.The operation of low power laser system based on biostimulation of the wounded area by LPL system on the wound that was made on the back of the mouse. Then the histological study was done within a period from day one after injury to day fourteen to find the differences between the treated groups and untreated group. Continuous beam and pulsed beam diode laser with power 3.7 mW and wavelength 650 nm was used.From the results, we found that the pulse diode laser has more effect than continuous laser diode regarding to the enhancing them process of wound healing. This indicates that continuous laser therapy group has a delayed period in wound healing properly due to its decrease affects of cell proliferation and vascularization.
