objectives: the purpose of this experimental study was to evaluate the efficacy of low level laser therapy (lllt) for pain reduction after midpalatal expansion in rats. materials and methods: sixty male sprague six-week old rats weighing 180±10g were divided into seven groups (two experimental groups of 24 rats and one control group of 12 rats). the experimental groups were subjected to expan...
background: numerous in vitro reports suggest that low level laser therapy (lllt) affects cellular processes by biostimulation, however most of them emphasize on using visible light lasers which have low penetration. the aim of this study was to determine the effect of infrared laser light (which is more useful in clinic because of its higher penetration) on secretion of fibroblast growth facto...
SUMMARY 13 Consecutive patients who underwent endoscopic Nd - Y AG laser therapy for palliation of advanced esophageal cardnoma were treated between Oct 1989, and July 1991 , in Khatam - al -Anbia Hospital. All patients had severe dysphagia and conventional methods such as surgery , Radiotherapy and chemotherapy failed to treat them. Undoubtedly without laser therapy these patients did not see...
introduction : laser therapy prevents complications of proliferative diabetic retinopathy (pdr), central retinal vein occlusion (crvo) and branch retinal vein occlusion (brvr), but its effect on visual acuity is controversial. this study evaluated the effect of laser on visual acuity in these patients. materials and methods: this interventional study conducted before–after treatment and evaluat...
Radiation damage depends on energy absorption, and is approximately proportional to the absorbed energy density in the tissue. In external radiation consideration with a certain energy flux, the amount of absorbed dose in each point of the tissue depends on the type of radiation, the radiation energy, the depth of the place of receipt, and the main components of the absorber environment. The ab...
low-power lasers are a group of lasers with a power less than 500 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. the purpose of this study was to review the clinical applications of these lasers and their success rate in different studies in orofacial pains. the articles with the key word “low level laser th...
Background: This study was designed to compare low-level laser therapy (LLLT) + exercise therapy with LLLT alone and exercise therapy alone, and to determine whether laser therapy is a useful treatment modality for chronic low back pain (LBP). Materials and Methods: This study was a double-blind placebo-controlled randomized clinical trial. Patients with chronic LBP for at least 12 weeks were ...
evidence acquisition we searched pubmed, google scholar and the cochrane databases for systemic reviews, review articles, meta-analysis and randomized clinical trials up to december 2013. results in this review, the efficacy and safety of the more commonly used cam methods for the treatment of obesity, namely herbal supplements, acupuncture, and non-invasive body-contouring, are briefly discuss...
