| ABSTRACT Objective: The aim of this study aimed to asses the effects of Light Emitting Diode Therapy (LEDT) on wound healing in rats using different wavelengths of LEDs: 680, 730, 950 nm simultaneously. Background Data: Light Emitting Diode Therapy (LEDT) developed from Sim-Med Ltd; using GaAs semiconductor as the diode for delivering light deep into tissues to promote wound healing and tissue growth. We review in this paper and present our data of LED treatment for wound healing to rats. Material and Methods: To perform this study we used variety of wavelengths, power density, and energy density parameters for each wound in 2groups of rats (104 rats), also we used lens to maximize the power and reduce the exposure time in the second experiment. Results: we found that LED with three wavelengths (680, 730, 950 nanometer) increase wound healing process in rats in first experiment more than second experiment which used lens to maximize the power. Conclusion: The results of the study demonstrated that the LED with three wavelengths (680, 730, 950 nanometer) simultaneously with contact control increase the wound healing of the rats. The results also showed that LED has large spot size than the laser so LED is more suitable than laser for large wounds, moreover the combined wavelengths of laser optimal for wound healing cannot be efficiently produced, and the size of wounds which may be treated by lasers is limited. | ||
