Although low-power laser irradiation provides many anabolic effects such as acceleration of bone formation, the effects of different pulse frequencies used during laser irradiation on bone formation have not been elucidated. Osteoblastic cells isolated from fetal rat calvariae were irradiated once with a low-power Ga-Al-As laser (830 nm, 500 mW) in two different irradiation modes; continuous ir...

PURPOSE The meta-analysis was performed to identify animal research defining the effects of low power laser irradiation on biomechanical indicators of bone regeneration and the impact of dosage. METHODS We searched five electronic databases (MEDLINE, EMBASE, PubMed, CINAHL, and Cochrane Database of Randomised Clinical Trials) for studies in the area of laser and bone healing published from 19...

Introduction: Skin cancer has been increased day by day, but it can be cured if it diagnosed early. After reviewing the scientific literature about 980 nm diode laser, and its multiple advantages on skin diseases. We studied in this paper the effectiveness of this type of laser on the progression of skin cancer among hamsters which were exposed to carcinogen on the bac...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

in russia (formerly ussr) study of biomodulation action (bma) mechanisms of low-intensity laser irradiation (lili) began in 1964, immediately after the development of lasers. during the period from 1965 to 1972 several dozens of scientific conferences were held, hundreds of studies were published. generally, secondary mechanisms and results of lili effect on patients with various diseases were ...

introduction: pulsed dye laser (pdl) is an important treatment for superficial infantile hemangioma, but few studies report on its cellular mechanism. the aim of this study was to evaluate alterations of serum vascular endothelial growth factor (vegf) level in infantile hemangioma (ih) patients after laser treatment and effects of pdl irradiation on human umbilical vein endothelial cells (huvec...
