OBJECTIVES To analyze the effects of low-level laser therapy (LLLT), 670 nm, with doses of 4 and 7 J/cm(2), on the repair of surgical wounds covered by occlusive dressings. BACKGROUND DATA The effect of LLLT on the healing process of covered wounds is not well defined. MATERIALS AND METHODS For the histologic analysis with HE staining, 50 male Wistar rats were submitted to surgical incisions and divided into 10 groups (n = 5): control; stimulated with 4 and 7 J/cm(2) daily, for 7 and 14…

Effects of laser irradiation at different wavelengths (660, 810, 980, and 1,064 nm) on mucositis in an animal model of wound healing

It is suggested that low-level Nd:YAG and 980-nm diode laser therapy accelerate the wound healing process by changing the expression of PDGF and bFGF genes responsible for the stimulation of the cell proliferation and fibroblast growth.

Effect of photobiomodulation (670 nm) associated with vitamin A on the inflammatory phase of wound healing

It is shown that laser plus vitamin A enhances healing by reducing the wound area and may have potential application for clinical management of cutaneous wounds.

Light-based therapy on wound healing : a review

The effects induced by light source (laser and incoherent light like LED) on different biological targets and the appropriate dose appears to be between 1 and 5 J cm−2, with an advantage on tissue interaction and 25% has no effect or inhibition on the healing process.

Effects of low-power light therapy on wound healing: LASER x LED*

LED and LASER promote similar biological effects, such as decrease of inflammatory cells, increased fibroblast proliferation, stimulation of angiogenesis, granulation tissue formation and increased synthesis of collagen, which are dependent on irradiation parameters, mainly wavelength and dose.

Laser phototherapy improves early stage of cutaneous wound healing of rats under hyperlipidic diet

It can be concluded that the hyperlipidic diet modified the inflammation pattern in wound healing and that laser light has a positive biomodulative effect on the healing process only in early stages.

The photobiomodulation (658, 830 and 904nm) on wound healing in histomorphometric analysis

Photobiomodulation was effective to stimulate the tissue repair process, with better results for the 658 nm wavelength.

The effect of low-level laser therapy (660 nm) on the gene expression involved in tissue repair

The LLLT (660 nm) at the dose of 5 J/cm2 should modulate cellular viability, upregulated VEGF, and downregulated IL6 expression of messenger RNA in culture of L929 fibroblast cells.

Histomorphometric evaluation of the effects of various diode lasers and force levels on orthodontic mini screw stability.

Low-level laser therapy may be a supplementary treatment method to increase the stability of the orthodontic mini screw by histomorphometrically analyzing the effects of different laser dose and force levels using white rabbits.



The influence of low-level laser therapy on biomodulation of collagen and elastic fibers.

It was concluded that low-level laser therapy contributed to a larger expression of collagen and elastic fibers during the early phases of the wound healing process.

Dose and wavelength of laser light have influence on the repair of cutaneous wounds.

It is concluded that low-level light therapy (LLLT) can have a positive biomodulatory effect on the repair of cutaneous wounds.

Low-level laser therapy (LLLT) efficacy in post-operative wounds.

Clinical evaluation showed that the healing process of these postoperatively treated wounds has occurred and that the functional recovery of the patients was faster than without treatment, and low-level laser radiation with wavelength of 904 nm to stimulate postoperative aseptic wounds (early scar).

Occlusion versus air exposure on full-thickness biopsy wounds.

Treatment with occlusive dressings increased early epithelial migration of acute full-thickness biopsy wounds compared with air exposure in healthy men.

Low-Level Laser Therapy Facilitates Superficial Wound Healing in Humans: A Triple-Blind, Sham-Controlled Study.

The untreated wounds in subjects treated with LLLT contracted more than the wounds in the sham group, so L LLT may produce an indirect healing effect on surrounding tissues, and data indicate that LLLt is an effective modality to facilitate wound contraction of partial-thickness wounds.

A comparative study of the effects of electrical stimulation and laser treatment on experimental wound healing in rats.

Both ES and laser treatment can be used successfully in decubitis ulcers and chronic wounds, in combination with conventional therapies such as daily care and debridement of wounds; however, ES has more beneficial effects during the inflammatory phase in some parameters than laser treatment.

The biomechanical and biochemical results collectively suggest that laser photostimulation promotes the tissue repair process by accelerating collagen production and promoting overall connective tissue stability in healing wounds of diabetic rats.

Effect of helium-neon laser on wound healing.

The mean breaking strength, as measured by the ability of the wound to resist rupture against force, was found to be significantly increased in the test group, and early epithelization, increased fibroblastic reaction, leucocytic infiltration and neovascularization were seen in the laser irradiated wounds.

The efficacy of low-power lasers in tissue repair and pain control: a meta-analysis study.

The findings mandate the conclusion that laser phototherapy is a highly effective therapeutic armamentarium for tissue repair and pain relief.
