introduction dentine hypersensitivity is a common clinical problem in dental practices. so several methods such as, nd: yag laser have been used to treat this problem. previous studies reported that nd:yag laser irradiation on root surface makes some thermal changes, like dentine melting and some other side effects which are related to power of laser irradiation. the aim of our study was to com...
متن کاملHistological Changes of Diaphyse of Tibia and its Central Medulary Chanal Follwing Low-Power Laser Irradiation in Rabbit
Purpose: The reaction of compact bone of diaphyse of tibia and it's bone marrow to low power laser radiation was investigated. Materials and Methods: Ten adult male rabbits were divided randomly into experimental and control groups. Low-power He-Ne laser (36 J/cm2) were radiated into a fixed point of tibia daily for 14 consequative days. Rabbits of control group did not receive laser. At the e...
متن کاملOver-expression of CXCR4, a stemness enhancer, in human blastocysts by low level laser irradiation
The key role of chemokine receptor CXCR4 in the maintenance of stemness property of stem cells has been shown recently. The low level laser irradiation (LLLI) is being used currently in a wide variety of clinical cases as a therapeutic tool for wound healing, relieving pain and destroying tumor cells. The aim of this study was to evaluate the effect of LLLI mimicking low level laser therapy (LL...
