BACKGROUND Low-level laser therapy (LLLT) has been shown to modulate the inflammatory process without adverse effects , by reducing pain and swelling and promoting the repair of damaged tissues. Because pain, swelling and muscle spasm are complications found in virtually all patients following oral surgery for the removal of impacted teeth, this model has been widely used to evaluate the effect...
Background and Aims : Free gingival graft is one of the most predictable procedures for gingival augmentation, but patient’s discomfort and pain during healing period of palatal donor site is a significant concern. The aim of this study was to evaluate the effect of 660nm low power laser on pain and healing in palatal donor sites. Materials and Methods: The present split mouth randomized co...
BACKGROUND AND OBJECTIVE Brain function is highly dependent on cerebral blood flow (CBF). The precise mechanisms by which blood flow is controlled by NIR laser irradiation on the central nervous system (CNS) have not been elucidated. In this study, we examined the effect of 808 nm laser diode irradiation on CBF in mice. STUDY DESIGN/MATERIALS AND METHODS We examined the effect of NIR irradiat...
introduction: the aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (pdt) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. methods: in this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. after conventional chemo mechanical preparation of root canals, microb...
introduction: low-level laser therapy (lllt) is thought to have analgesic and biomodulatory effects. our objective was to assess the pain-relieving effect of lllt and possible changes in joint stiffness and disability of patients with knee osteoarthritis (koa) and compare it to the more commonly used modality; therapeutic ultrasound(us). methods: 37 patients with mild or moderate koa were rando...
low-power lasers are a group of lasers with a power less than 250 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. these lasers have analgesic features with their ability to trigger reactions that reduce pain and inflammatory mediators. low-power lasers can also be used instead of needles in acupuncture to dec...
The aim of the present study was to perform a systematic review of the literature on the effects of low-level laser therapy in the treatment of TMD, and to analyze the use of different assessment tools. [Subjects and Methods] Searches were carried out of the BIREME, MEDLINE, PubMed and SciELO electronic databases by two independent researchers for papers published in English and Portuguese usin...
background: in the light of various applications of uv laser in biological system, we have investigated the effect of picosecond uv laser radiation on silkworm bombyx mori. materials and methods: the eggs of nb4d2 of different stages were exposed to pico second pulse laser at 355 nm from nd:yag laser for different durations. results: due to irradiation alterations in crescent larval body markin...
