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...

radiotherapy in the head and neck region and chemotherapy might give rise to oral mucositis which is a severe and painful inflammation. there is no known definite cure for mucositis. a number of studies have attempted to evaluate the effect of low-power laser on radiotherapy- and chemotherapy-induced mucositis. the present study was undertaken to evaluate the effect of low-power laser on the pr...

treatment protocols with low-level laser (also called ‘soft laser therapy) have been used in health care systems for more than three decades. bearing in mind the suitable sub-cellular absorption and the cellular-vascular impacts, low-level laser may be a treatment of choice for soft tissues. low-level lasers have played crucial and colorful roles in performing periodontal surgeries. their anti-...

The LLLT literature is large, with more than 1000 papers published on this topic. A problem in dissecting this literature is the variation in methodology and dosimetry between different studies. Not only have a range of different wavelengths been examined, but exposure times and the frequency of treatments also vary. The inclusion of sham-irradiated controls in clinical studies is an important ...

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...

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...

Low Level Laser Therapy (LLLT) is controversial because of conflicting outcomes in peer reviewed literature. The possible combination and permutation of laser parameters is almost infinite. Defining what is an appropriate dose of laser energy for anyone condition remains anecdotal. A number of factors have contributed to the heterogenity of the literature and the variable outcomes. This paper e...

low-level laser therapy (lllt) provides several benefits for patients receiving orthodontic treatment. according to some literatures, orthodontic tooth movement (otm) can be enhanced but some investigators have reported contradictory results. this article reviews the literature regarding the different aspects of the use of lllt on otm and its alterations. the general data regarding the study de...
