Objective. To evaluate the tissue repair posterior to realization of technical partial paladin, as treatment of palatitis in equine. Materials and methods. 12 horses were used, divided aleatorily in two groups, both with six animals, to those of first group were practiced partial paladin with saturation and to those of the second group, partial paladin were practiced and then cauterization. The groups were divided in three subgroups of two animals each one. To the first ones sutured and cauterized, biopsy were taken the day 5; to the second ones the day 15 and at the third ones the day 30 post surgeon. Results. The day 5 post surgeon, in both groups the presence of cellular infiltrate inflammatory was observed of mononuclear type, initiation of the epithelization process, fibroblastic proliferation and formation of new sanguine vessels; being noticed severe ulceration of the epithelium with abundant cellular detrituses in the cauterized animals. The day 15 post surgeon, in the sutured animals was observed infiltrated cellular mononuclear, epithelial proliferation and fibroblastic, and presence of new sanguine vessels. Samples of the cauterized animals also presented epithelial ulceration, cellular detritus and formation of disorganized granulation tissue. The day 30 post surgeon the sutured animals didn’t show evident inflammation, the epithelium was observed with normal characteristics although thicker that the adjacent one. In the cauterized animals, infiltrated cellular mononuclear was not observed, although the epithelial ulceration continued, equally existed disorganized fibroblastic proliferation and abundant collagen fibers. Conclusion. It is possible to conclude that the process of tissue repair was favored by the technique of partial paladin with suturation.
