statement of the problem: recurrent aphthous stomatitis (ras) is one of the most common lesions in the oral cavity. due to its multifactorial nature, there is no definitive treatment for ras. laser therapy is one of the suggested treatments to reduce patient’s discomfort. purpose: the purpose of the present clinical trial is to assess the effect of low and high level laser therapy on pain contr...

the effect of low intensity laser radiation in the treatment of acute and chronic pain is now established in many studies. trigeminal neuralgia is a pain passes through nerve’s branches and its trigger is located in skin or mucosa that could lead to pain with a trigger stimulus. the pain involved branches of trigeminal nerve that sometimes has patients to seek the treatment for several years. n...

a systematic review was conducted covering the action of red laser, infrared and combination of both, with emphasis on cutaneous wound therapy, showing the different settings on parameters such as fluency, power, energy density, time of application, frequency mode and even the type of low-power lasers and their wavelengths. it was observed that in general, the lasers brings good clinical and hi...

7 Emerging economies with rapidly growing population and energy demand, own some of the most 8 expensive power plants in the world. We hypothesized that corruption has a relationship with the 9 capital cost of power plants in developing countries such as Bangladesh. For this study, we analyzed 10 the capital cost of 61 operational and planned power plants in Bangladesh. Initial comparison study...

So far, researchers have developed simplified models to control the so called Acurex field, which is a solar power plant situated in Tabernas in Spain, used mainly for research purposes. Most of these simplified models for control have been used in simulation. Some have also been used in control experiments. Usually an advanced model of the plant was used to identify and verify the simplified m...

introduction: low-level laser therapy (lllt) is shown effective in healing diabetic foot ulcer when combined with conventional therapy. since; diabetes mellitus is a leading cause of impaired wound healing. the aim of this study is to determine the effect of different diabetic control’s methods on the healing response of diabetic foot ulcer in those patients treated with low level laser therapy...

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...

introduction: the use of lasers for treatment has become a common phenomenon in the medical field. currently, numerous laser systems are available for dental use. the use of lasers for periodontal treatment becomes more complicated because the periodontium consists of both hard and soft tissues. methods: related articles were gathered and selected carefully and reviewed. among the many lasers a...

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...

BACKGROUND AND OBJECTIVES The aim of this study was to determine whether low power laser therapy (Gallium-Arsenide) is useful or not for the therapy of chronic low back pain (LBP). STUDY DESIGN/MATERIALS AND METHODS This study included 75 patients (laser + exercise-25, laser alone-25, and exercise alone-25) with LBP. Visual analogue scale (VAS), Schober test, flexion and lateral flexion measu...
