Paper Abstract

A histopathological study on the effect of He-Ne laser treatment on the evolution of cat gingiva open wounds is presented. The irradiation initiates first a massive inflammatory cell exudate together with an antiedematic effect after the second postoperative day. A substantial acceleration of the healing process is noted on the sixth day among irradiated tissues as compared to the operated gingiva which still shows, at this period of time, inflammatory exudate and isolated fibroblasts. The persistence of inflammatory exudate and edema among the untreated gingiva seemed to have a delaying effect upon the healing process. The biostimulatory effect of soft laser seems to act photodynamically both at the intracellular level and extracellular millieu, thus promoting the proliferative capacity of fibroblasts and capillary buds formation necessary for a rapid differentiation of connective tissue. The controlled application of He-Ne laser treatment is suggested in dental healing procedures.
