dc.description.abstract | Iron deficiency impairs the formation of hemoglobin, red blood cells, as well the transport of oxygen. The wound healing process involves numerous functions, many of which are dependent on the presence of oxygen. Laser has been shown to improve angiogenesis, increases blood supply, cell proliferation and function.We aimed to study the effect of λ660 nm laser and λ700 nm light-emitting diode (LED) on fibroblastic proliferation on cutaneous wounds on irondeficient rodents. Induction of iron anemia was carried out by feeding 105 newborn rats with a special iron-free diet. A 1×1 cmwound was created on the dorsumof each animal that were randomly distributed into seven groups: I, control anemic; II, anemic no treatment; III, anemic+L; IV, anemic+ LED; V, healthy no treatment; VI, healthy+laser; VII, healthy+ LED (n015 each). Phototherapy was carried out using either a diode laser (λ660 nm, 40 mW, 10 J/cm2) or a prototype LED device (λ700±20 nm, 15 mW, 10 J/cm2). Treatment started immediately after surgery and was repeated at 48-h interval during 7, 14, and 21 days. After animal death, specimens were taken, routinely processed, cut, stainedwith hematoxylin-eosin, and underwent histological analysis and fibroblast counting. Significant difference between healthy and anemic subjects on regards the number of fibroblast between treatments was seen (p<0.008, p<0.001). On healthy animals, significant higher count was seen when laser was used (p<0.008). Anemic subjects irradiated with LED showed significantly higher count (p<0.001). It is concluded that the use of LED light caused a significant positive biomodulation of fibroblastic proliferation on anemic animals and laser was more effective on increasing proliferation on non-anemics. | pt_BR |
