Noise-induced hearing loss is a common type of hearing loss. The effects of laser therapy have been investigated from various perspectives, including in wound healing, inflammation reduction, and nerve regeneration, as well as in hearing research. A promising feature of the laser is its capability to penetrate soft tissue; depending on the wavelength, laser energy can penetrate into the deepest...

background and aims. muscular pain in the facial region is the most common cause of facial pains. myofascial pain dysfunction syndrome (mpds) is one of the most important facial muscle disorders comprising of signs and symptoms including pain during function, tenderness in the muscles of mastication and restricted jaw movement. due to the lack of an accepted therapeutic approach, the purpose of...

introduction: the aim of this study was to assess the caries-preventive potential of carbon dioxide (co2) laser application in conjunction with the use of titanium tetra fluoride solution on the enamel adjacent to bracket. methods: seventy-five freshly extracted bovine incisors were used. in order to attach the brackets, the area of examination was covered with adhesive tape to limit acid etchi...

introduction : intestinal ischemia and reperfusion (i-i/r) is an insult associated with acute respiratory distress syndrome (ards). herein we evaluate the dose-response effect of low-level laser therapy (lllt) on lung inflammation induced by i-i/r. methods : mice were subjected to mesenteric artery occlusion (45 min) and killed after clamp release and intestinal reperfusion (2h). increasing dos...

the use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. this review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

low level laser therapy (lllt) uses a light source that generates extremely pure light, of a single wavelength1. the effect is not thermal, but rather related to photochemical reactions in the cells. lllt was introduced as an alternative non-invasive treatment for oa about 10 years ago, but its effectiveness is still controversial2. a cochrane review of lllt in osteoarthritis included five tria...

Port- wine stain is a congenital vascular malformation originating from superficial dermal vessels which is characterized by ectasia of the capillaries. Currently, pulsed dye laser (PDL) is used to treat these vascular lesions. To date, there are few reports of eczematous lesions due to PDL. Herein, we report three cases of eczema following PDL, used for treatment of port- wine stain in Razi ho...

introduction: our aim was to compare the cost effectiveness of holmium laser prostate enucleation (holep) versus trans-urethral resection of prostate. methods:  we searched all available databases for any controlled trials comparing holep and turp from january 2000 to february 2009. two independent reviewers studied and appraised the selected evidences. then, effectiveness and cost effectivenes...
