the key role of chemokine receptor cxcr4 in the maintenance of stemness property of stem cells has been shown recently. the low level laser irradiation (llli) is being used currently in a wide variety of clinical cases as a therapeutic tool for wound healing, relieving pain and destroying tumor cells. the aim of this study was to evaluate the effect of llli mimicking low level laser therapy (ll...

introduction: osteoarthritis (oa) is a common degenerative joint disease particularly in older subjects. it is usually associated with pain, restricted range of motion, muscle weakness, difficulties in daily living activities and impaired quality of life. to determine the effects of adding two different intensities of low-level laser therapy (lllt) to exercise training program on pain severity,...

introduction: dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. the purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity. methods: in this pil...

several methods have been employed for cancer treatment including surgery, chemotherapy and radiation therapy. today, recent advances in medical science and development of new technologies, have led to the introduction of new methods such as hormone therapy, photodynamic therapy (pdt), treatments using nanoparticles and eventually combinations of lasers and nanoparticles. the unique features of...

a systematic review was conducted covering the action of red laser, infrared and combination of both, with emphasis on cutaneous wound therapy, showing the different settings on parameters such as fluency, power, energy density, time of application, frequency mode and even the type of low-power lasers and their wavelengths. it was observed that in general, the lasers brings good clinical and hi...

this study is focused on investigating the parameters of laser percussion drilling process of nickel-base super alloy inconel 718 with thickness of 1 mm. fiber laser with the power of 500 watts was used as the laser source. laser pulse frequency, duty cycle, laser power, focal point position, were assumed as the laser drilling process variables. the hole geometry features, i.e. entrance hole di...

temporomandibular disorders (tmd) are clinical conditions characterized by pain and sounds of the temporomandibular joint (tmj). this study was designed to assess the effect of low-level laser therapy (lllt) on healing of osteoarthritis in rats with tmd.thirty-two male wistar rats (250-200 g) were housed in standard plastic cages. after injection of complete freund's adjuvant into the tmj, rats...

BACKGROUND AND OBJECTIVES The aim of this study was to determine whether low power laser therapy (Gallium-Arsenide) is useful or not for the therapy of chronic low back pain (LBP). STUDY DESIGN/MATERIALS AND METHODS This study included 75 patients (laser + exercise-25, laser alone-25, and exercise alone-25) with LBP. Visual analogue scale (VAS), Schober test, flexion and lateral flexion measu...
