Effect of low-power laser irradiation on bony implant sites.
This study was designed to examine the effects of low-energy laser irradiation on osteocytes and bone resorption at bony implant sites. Five male baboons with a mean age of 6.5 years were used in the study. Four holes for accommodating implants were drilled in each iliac crest. Sites on the left side were irradiated with a 100 mW low-energy laser (690 nm) for 1 min (6 Joule) immediately after d...
متن کاملEffect of Low- Power Helium-Neon Laser Irradiation of Healing of Incisized Medial Collateral Ligament of Knee in Rars
Purpose: The aim of the present study is to investigate the effects of LPL on healing of incisized medial collateral ligament (MCL) of knee of rats. Materialsand Methods:MCL of right hind limb of 30 rats were transversly incisied. LPL (Helium- Neon, Continuose, output 10mW) were exposed (10 mJ/cm2 and 1.2 J/cm2) daily to group 1& II (experimental groups) respectively. In control group MCL were...
متن کاملEffectiveness of transmeatal low power laser irradiation for chronic tinnitus.
OBJECTIVE To evaluate effectiveness of 5 mW laser irradiation in the treatment of chronic tinnitus. STUDY DESIGN Prospective, randomised, double-blind study. METHODS This investigation included 66 ears in 45 patients with chronic unilateral or bilateral tinnitus. A 5 mW laser with a wavelength of 650 nm, or placebo laser, was applied transmeatally for 15 minutes, once daily for a week. A qu...
متن کاملPulse irradiation of low-power laser stimulates bone nodule formation.
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...
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...
