The effect of low level laser (GaAlAs) therapy on the post-surgical healing of full thickness wounds in rabbits

Abstract

Summary Objective Our purpose was to determine the efficacy of low level laser therapy (LLLT) on wound healing in rabbits. Study design Sixteen rabbits were sedated and given a general anesthetic. A full thickness flap was used bilaterally at the buccal gingiva maxilla in a naturally toothless area, and then sutured. A low level pulsed GaAlAs laser (wavelength: 685 nm, power: 45 mW, radiant exposure: 3 J/cm 2 , frequency: 10 Hz, duty factor: 80%; application time: 1 min) was used on the left side. The right side was not lasered as a control. Tissue specimens from each site on days 3, 7, and 14 after surgery were examined microscopically. Results Less inflammation was observed on days 3 and 7 in the treatment group ( p p > 0.05). Conclusion LLLT using optimal parameters can accelerate full thickness wound healing.
