Abstract

The goal of this investigation was to histologically evaluate the healing and revascularization of the subepithelial connective tissue graft in dogs. Six beagle dogs were used in this study. Recession defects were surgically created on maxillary left P2 and right P2, and maxillary and mandibular left central and lateral incisors. The defects were left untreated for 35 days. After elevating a split thickness flap, the graft was harvested from the palate and placed over the denuded root surfaces. The flap was then coronally repositioned and sutured. Three dogs provided the specimens for 7- and 14-day time points and 3 dogs for 28- and 60-day time points. The animals were sacrificed and the blocks obtained were divided in half. One half was processed following the Spalteholtz method and the other was processed for routine histologic examination. At 7 days, a clot was present at the demarcation zones and it was more organized at 14 days. At 28 days, the junctional epithelium was formed and the demarcation zones could not be delineated. At 60 days, the oral epithelium had regained its normal appearance. The attachment of the graft to the root surface was mediated by a combination of epithelial downgrowth and connective tissue attach...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
