Objective:
The purpose of this work was to conduct a literature search on the use of laser therapy in the tissue repair process, addressing different lasers and parameters used by the authors.
Methods:
We conducted a literature review of electronic databases to search for articles that investigate the effects of laser therapy on wound healing in rats, mice, and humans with specific diseases, published from January 2008 to March 2013.
Results:
In the 31 articles selected, the most frequently used type of laser was gallium-aluminium-arsenium (GaAIAs) in male rats. We noted that the protocol for laser application differed from author to author, making it difficult to compare results regarding the choice of parameters and treatment protocol.
Conclusions:
Laser therapy had a positive effect on the healing process of cutaneous lesions in rats, which was not observed in humans.
Insights
Laser therapy shows promise for wound healing in rats, but varied application protocols hinder direct comparisons. Its effectiveness in humans with specific diseases remains unconfirmed by this review.
Area of Science:
- Biomedical Engineering
- Regenerative Medicine
- Photomedicine
Background:
- Tissue repair is a complex biological process crucial for healing.
- Laser therapy has emerged as a potential therapeutic modality for accelerating tissue regeneration.
- Understanding optimal laser parameters is essential for effective clinical application.
Purpose of the Study:
- To conduct a comprehensive literature search on laser therapy's role in tissue repair.
- To identify and analyze different types of lasers and parameters employed in wound healing studies.
- To evaluate the reported effects of laser therapy on wound healing across various models.
Main Methods:
- A systematic literature review was performed using electronic databases.
- Articles published between January 2008 and March 2013 were included.
- Studies focused on laser therapy for wound healing in rats, mice, and humans with specific diseases.
Main Results:
- Thirty-one articles were selected for analysis.
- Gallium-aluminum-arsenide (GaAIAs) lasers were most frequently utilized, primarily in male rats.
- Significant variability in laser application protocols and parameters was observed, complicating result comparison.
Conclusions:
- Laser therapy demonstrated a positive impact on the healing of cutaneous lesions in rats.
- The positive effects observed in rats were not consistently replicated in human studies.
- Further research with standardized protocols is needed to confirm efficacy in humans.
