How does laser therapy contribute to wound healing?

• A. By reducing blood flow around the wound
• B. By promoting collagen synthesis and enhancing cellular proliferation
• C. By minimizing inflammation
• D. By decreasing the skin's sensitivity

Answer: (B)

Laser therapy contributes to wound healing primarily by promoting collagen synthesis and enhancing cellular proliferation. Collagen is a crucial protein that provides structure and strength to the skin and other tissues. When laser therapy is applied, it stimulates fibroblasts, which are the cells responsible for producing collagen. This stimulation leads to an increase in collagen deposition at the wound site, facilitating better tissue repair and regeneration. Additionally, laser therapy enhances cellular proliferation by encouraging the growth and division of cells involved in the healing process. This includes various cell types that play a role in tissue repair and growth, such as keratinocytes and endothelial cells. The overall result is a more efficient and effective healing response, decreased healing time, and improved overall outcomes for the patient. While the other choices may relate to aspects of wound management, they do not encompass the primary mechanisms through which laser therapy enhances healing. For instance, while minimizing inflammation can be beneficial in some contexts, it is not the primary function of laser therapy in wound healing. Reducing blood flow contradicts the healing process, as adequate blood flow is necessary for supplying nutrients and oxygen to the tissues. Lastly, decreasing skin's sensitivity does not directly correlate with the healing benefits offered by laser therapy.
