any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Abstract Background and aim: One of the most common complications in the treatment of fixed orthodontics during treatment is periodontal problems. Different therapies such as mouthwashes, antibiotics and today laser therapy are used to treat periodontal problems in orthodontic patients. The aim of this study, is that we evaluated the effect of the Diode laser on the number of four periopathog...
background and objective: genital warts, due to specific types of the human papillomavirus, have long been regarded as one of the most important causes of cervical cancer and one of the most common cause of sexually transmited diseases (stds). over the years, it has been the focus of several studies in order to find the best effective approach to eradicate the virus, however there are still co...
background: the effectiveness of low power lasers on incisional wound healing, because of confl icting results of previous studies, is uncertain. therefore, the aim of this study was to evaluate the effects of low-level helium-neon (he-ne) laser irradiation on wound healing in rat’s oral mucosa. materials and methods: sixty-four standardized incisions were carried out on the buccal mucosa of 32...
Purpose: Osteoarthritis is one the most common chronic diseases of the joints that mostly affects knee joint. Low power laser is one the minimally invasive treatments of osteoarthritis. However, the efficacy of this therapy is still controversial. This study aimed to evaluate the efficacy of low power laser therapy in reducing pain and increasing knee range of motion compared to placebo laser. ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
This article has discussed selected applications of laser therapies in otolaryngology. Lasers are the treatment of choice for PWS lesions, but new advances are needed to achieve complete blanching in the majority of cases. Noninvasive in vivo imaging and laser therapy coupled with PDT are two areas showing promise to improve outcome. PDT has the potential to offer new, cost-effective treatment ...
