external root resorption may be an uncontrolled phenomenon, and the most known interventions have no effect. even progressive external root resorption may not be controlled by long term ca(oh)2 therapy. currently, there are no treatment options for vital tooth that suffer from root resorption. this invasive resorption can lead to extraction of the tooth. the use of new technologies such as low ...

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...

introduction: the effectiveness of low power lasers for incisional wound healing, because of conflicting results of previous research studies, is uncertain. therefore, this study was carried out to evaluate low power laser effects on incisional wound healing. materials and methods: incisional wound was produced on thirty-six mature male guinea pigs under general and local anesthesia. in half of...

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...

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...

there is just one study about the effects of 830 nm low power laser (lpl) on conduction velocity of sural nerve in human. considering the fact that the sural nerve is a pure sensory nerve, therefore, for determining the effect of lpl on electrophysiological parameters of the nerve in human, this study was carried out as a base for further basic and clinical researches. thirty eight normal volun...
