effect of low-level laser therapy on dental pain induced by separator force in orthodontic treatment
background: patients undergoing orthodontic treatment experience varying degrees of pain with separator insertion. a survey of patients’ attitude towards orthodontic treatment revealed that pain was the most discouraging factor related to their treatment. moreover, it was the highest ranking reason for wanting to discontinue care. the purpose of this study was to determine the effect of low-lev...
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...
Introduction: Spinal cord injury is one of the important unresolved problems in the medical society leading to adverse consequences, such as motionlessness and neuropathic pain. Neuropathic pain is seen in both forms of hyperalgesia and allodynia. In this study, the effects of low-level laser radiation on hyperalgesia pain have been investigated. Material & Methods: In this experimental stu...
Background: Laser-tissue interaction on low-level laser therapy (LLLT) has widespread medical applications (e.g., improved wound healing). The tensile strength of radiated tissue by LLLT is known to be increased mainly because of cross collagen bands developed after radiation.Objective: In this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic ti...
Purpose: The aim of present investigation was to determine the effects of low- level He-Ne laser therapy on biomechanical property of skin wound of healthy and streptozotocin induced diabetic (STZ-D) rats. Materials and Methods: The study was performed by experimental method.36 male adult Wistar rats weighing above 250 gr. were used. Rats were divided equally into control and experimental group...
Background Sperm motility is known as an effective parameter in male fertility and it depends on energy consumption. Low level LASER irradiation could increases energy supply to the cell by producing of adenosine triphosphate (ATP). The purpose of this study is to evaluate how the low level LASER irradiation affects the human sperm motility. MaterialsAndMethods Fresh human semen specimens of as...
Muscular pain is one of the most common causes for facial pain. Myofacial pain dysfunction syndrome (MPDS) is one of the most important disorders of facial area that affected patients suffer from pain, tenderness of one or more masticatory muscles and limitation of movements. Lack of specific and effective therapeutic method, makes it necessary to find a treatment to decrease pain. Considering ...
Purpose: The aim of present study is to evaluate the effect of a pulsed infrared low-level laser on wound healing in an experimental induced diabetic rat model.Materials and Methods: 18 adult rats were divided into 2 healthy and 1 diabetic groups. Diabete was induced by intraperitoneal administration of streptozotosin in diabetic group. Two full - thickness skin incisions were made on the dorsu...
