Introduction Monosodium urate (MSU) crystals deposition, notably associated with gout, poses significant health risks. Given the relevance of alternative methods for reducing MSU levels, low-level laser therapy (LLLT) has emerged as a promising treatment approach. The proposed study aimed to evaluate the effectiveness of LLLT in mitigating MSU. Methodology Utilizing fixed incidence angles of 90°of red and infrared light sources at three wavelengths of 650 nm, 780 nm, and 830 nm (5 mW power, 5 V), irradiated onto synthetic MSU crystals suspended in phosphate-buffered saline (PBS) solution (pH 7.4, flow at 40 cm/s, 37 °C). Exposure times were from 0 to 25 min, with increments of 5 min per time. Results Microscopic observation revealed a reduction in the quantity of synthetic MSU crystals after exposure to LLLT. Notably, the 650 nm wavelength exhibited the highest efficacy, particularly at the 25-min exposure mark. Conclusion and Discussion This reduction in urate crystals can be attributed to the photochemical interaction of light with crystals, leading to alterations in molecular structure. The findings underscore the significant potential of laser therapy in managing inflammatory conditions and tissue lesions associated with crystalline pathologies.
