Abstract
The purpose of this investigation was to study the redevelopment
of the blood supply of free gingival grafts, in dogs, and to detennine
how the graft is nurtured prior to redevelopment of a true circulation.
The preparation of the recipient site, in attached gingiva of premolar
and molar areas, was done by sharp dissection of gingiva to its periosteal
aspect. Split-thickness grafts (approximately 1 mm. in thickness),
circa 4 x 8 mm. in size, taken fran attached gingiva of canine areas,
were then sutured on the prepared bed. The animals were sacrificed
immediately after surgery and at varying intervals of time up to twenty
days. Aproximately fifteen minutes prior to sacrifice, the animals
were vitally perfused, bilaterally, through the cam1on carotid arteries,
at existing arterial blood pressure. A filtered carbon black suspension
(Pelikan Ink, Gunther Wagner) and a 1% solution of Patent blue Violet,
a diffusible dye, canprised the perfusate. This permitted the delineation
of the blood supply and its permeability in undecalcified cleared
and decalcified histologic specimens. [TRUNCATED]
