Class IV Laser Treatment

Class IV laser treatment is a non-invasive procedure for healing various ailments that cause discomfort in the foot and ankle.
1.Accelerated cellular reproduction and growth – which is key in repairing the cells of cartilage, bone, tendons, ligaments, and muscle tissue.Reduced scar tissue that typically develops from specific injuries. When patients have less scar tissue, the likelihood of chronic pain is also reduced.

2.Decreased inflammation and increased blood circulation:With 26 bones in the foot alone, as well as major ligaments, tendons, joints, and nerves.

3.It can help manage chronic pain, speed up healing, and reduce inflammation by targeting deep layers of the body's tissues.When the light source is placed against the skin, photons penetrate several centimeters down and are absorbed by the mitochondria (the energy-producing part of a cell). This energy results in the restoration of normal cell function.

Abstract: The aim of this study was to investigate the effect of COZING laser irradiation on tibial bone repair in osteoporotic rats. The experimental animals were randomly divided into eight experimental groups according to ovarian hormone (sham-operated group) or ovarian hormone deficiency (depopulated group) and the condition of receiving irradiation or not receiving irradiation. Low-intensity 904 nm laser (50 mJ/cm2) accelerates the repair process of osteoporotic fractures, especially at the initial stage of bone regeneration.



INTRODUCTION: The development of new techniques to accelerate the process of bone repair has led to significant advances in the treatment of fractures. The effects of biostimulation on bone have received much attention in recent years.



METHODS: Forty-eight adult rats were randomly divided into 8 experimental groups (6 rats per group), each group being divided according to the presence of ovarian hormones (sham-operated group) or the absence of hormones (ovariectomized (OVX) group), and whether they were irradiated by radiation or not. For application of low-intensity laser therapy, the animals were anesthetized with one-third of a dose sufficient to immobilize the animals and then irradiated with a COZING laser (904 nm, 50 mJ/cm(2) for 2 seconds, point contact). Control animals received the same manipulation as those receiving radiation, but with the laser turned off. Half of the animals were executed 7 days after repair of the bone defects, and the other half were executed 21 days after the operation. After complete demineralization, the tibia was transected in the central region of the bone defect and embedded in paraffin blocks. These blocks were then cut into semi-continuous slices and stained with hematoxylin and eosin.



Results: Animals in the ovariectomized group that received laser treatment showed new bone formation when they were executed 7 days later (p < 0.001). Animals in the ovariectomized group that did not receive laser treatment had the lowest percentage of bone formation when they were executed after 7 days (p > 0.05). All animals executed after 21 days showed linear closure of the lesion.

CONCLUSIONS: Low-intensity 904 nm laser (50 mJ/cm2) accelerates the repair process of osteoporotic fractures, especially in the initial stages of bone regeneration.
