The goal of this study was to see how Low Level Laser Therapy (LLLT) (904 nm) affected the repair of standardised bone lesions in rats’ femurs. Sixty male wistar rats were divided into two groups of similar size. A group (laser group) and a group (non-laser group) (B: control group). All rats had a surgical fracture in the central portion of their femur. In group (A), a continuous wave 904 nm infrared laser with a dosage of 4 j/cm2 was delivered to the fracture site for 7 sessions, each lasting 5 minutes. On the 15th, 30th, and 45th days after operation, the animals were killed by an overdose of general anaesthetic. The specimens were treated and stained with Hematoxylin and Eosin (H/E), as well as a unique stain called Masion trichrome, before being examined under a microscope. When comparing the irradiation and control groups, descriptive analysis of histological imaging revealed that the irradiated group had a higher degree of new bone formation, osteoblastic surface, and collagen fibre. Based on the findings, the researchers concluded that LLLT was effective in boosting bone healing and increasing new bone production in surgically fractured femurs in animals.
