over the past three decades physicians have used light level laser therapy (lllt) for the management and the treatment of diabetic peripheral neuropathy and have obtained results that calls for further investigations. this study aimed to investigate the effectiveness of lllt in treatment of pain symptoms in patients with diabetic polyneuropathy. in this study 60 patients with diabetic periphera...

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...

the aim of this study was to assess the surface of yttrium-stabilized tetragonal zirconia (y-tzp) after surface treatment with lasers and airborne-particle abrasion.first, 77 samples of presintered zirconia blocks measuring 10 × 10 × 2 mm were made, sintered and polished. then, they were randomly divided into 11 groups (n=7) and received surface treatments namely, er:yag laser irradiation with ...

This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered.

purpose: to evaluate the complications of scleral perforation during strabismus surgery and the role of cryopexy, laser therapy, and conservative management in an animal model. methods: in this experimental study, 42 pigmented-eye rabbits were included. an s-24 needle attached to a 6-0 polyglactin suture was passed through the sclera and into the vitreous cavity in both eyes of the animals. one...

purpose: retinopathy of prematurity (rop) adversely affects normal ocular vascularization in premature infants. it can be mild with no visual consequences, or may become aggressive with new vessel formation and even progress to retinal detachment and blindness. modern treatment can prevent blindness due to neovascularization but uncorrected refractive errors may lead to amblyopia. methods: in t...

introduction: endovenous laser therapy (evlt) for greater saphenous vein (gsv) insufficiency is a newly established method of treatment only recently made availablein iran. the present study seeks to describe the results of the first 20 patients treated with evlt at shohada-e tajrish medical center, tehran, iran. methods: 20 patients (16 male, 4 female) with the mean age of 38.9 and an average ...

introduction: tonsillectomy is among commonest otorhinolaryngologic surgeries. many methods have been used to control post surgical pain, but despite it, pain is still one of the problems related to this operation. recently, due to the non invasiveness of low level lasers, this modality has attracted attention. the purpose of this study is to evaluate the effects of low level laser irradiation ...

introduction: with the rapid increase in use of lasers in medical treatments, it is important to understand the mechanisms of heat transfer in biological tissues in order to minimize damage to the tissues resulting from extra heat applied. the aim of this study is to investigate the temperature distribution in living biological tissues when laser irradiation is used in a treatment. methods:  in...
