Low-level laser on femoral growth plate in rats

Abstract: PURPOSE:To determine the influence of low-level laser therapy on femoral growth plate in rats. METHODS:Thirty male Wistar rats aged 40 days were divided into two groups, G1 and G2. In G1 the area of the distal growth plate of the right femur was irradiated at one point using GaAlAs laser 830 nm wavelength, output power of 40 mW, at an energy density of 10 J/cm 2 . The irradiation was performed daily for a maximum of 21 days. The same procedure was done in G2, but the probe was turned off. Five animals in each … Show more

“…Some findings support that LLLT has the effects to induce chondrogenesis in vitro [28] and to improve cartilage structure in vivo [29, 30], while others prove that LLLT has no [31] or even negative [19] effect on bone growth. These differences require further study.…”

“…At least 5 measurements per sample were taken at three different locations by two observers blind to the experimental group. Each zone of the growth plate was also scored on a scale of 0–3 based on the number of chondrocytes within the same defined region: 0 = absent, 1 = moderate, 2 = discreet, and 3 = intense [19]. …”
