it is the output power and density of the lasers which determine whether a laser is a low or high-power one. if the density is less than 670mw/cm2, the laser is called a low power one. the output power of these lasers is usually less than 250mw. they use different mechanisms to accelerate wound healing such as: cellular biostimulation, improvement of circulation, vasodilation, analgesic and ant...

introduction: post-endodontic treatment pain is a relatively common condition which needs analgesics for patient’s pain relief. low-level laser therapy (lllt) is suggested as a non-pharmacological and non-invasive treatment for dealing with painful conditions. the purpose of this study was to evaluate the pain relief effect of lllt after endodontic treatment. methods: eighty patients randomly r...

conclusions accordingly, laser therapy in our protocol seemed to affect some of the nerve growth parameters, mostly on motor rather than sensory fibers. results in the two -point discrimination- test, there was no significant difference between the two groups in the thumbs but a significant improvement was observed in the index finger of the lt group. improvement of muscular examinations such a...

Akbari A1 1. Assistant Professor, Department of Physiotherapy, Faculty of Medicine, Zahedan University of Medical Sciences Abstract Background: Shoulder pain is the third most prevalent cause of musculoskeletal disorder after low back and cervical pains. Most of the shoulder symptoms are attributed to the rotator cuff. The objective of this study was to compare the effects of low-power ...

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 standards of endodontics have constantly been raised in the last 25 years by practitioners’ researches and their interest. most of the scientists believe the recent developments and the use of lasers as the most exciting achievement in endodontic treatment. nowadays, lasers are being used in endodontics to improve the prognosis of the root-filled teeth. the implement of suitable wavelengths...

background: neuropathic pain (np) is a serious suffering medical condition that frequently leads to disability and life style changes. although the exact mechanisms of np are still unknown, recently the role of reactive oxygen species (ros) reported as an important factor for np. apoptosis, increase of atp production and reduction of antioxidants are also the other factors influencing in np. th...
