The subepithelial connective tissue graft is a valuable technique used to cover exposed root surfaces or to increase the zone of attached gingiva. Cysts, such as the gingival cyst of the adult, are epithelial-lined cysts which may arise from heterotropic glandular tissue, a proliferating rete peg, remnants of the dental lamina, or traumatic implantation of epithelial tissue. In this paper, a case report is described of a "surgical cyst" or cystic morphogenesis of surgically implanted epithelium developing secondarily to a subepithelial connective tissue graft.

Although there were isolated differences, the overall trend was that the pluronic polyol and the mode of administration did not result in a significant change in bone wound healing as measured by the percentage of bone fill. Pluronic polyols may be considered as carriers for osseous graft materials.

These in vitro studies support the concept that EMP may act as a suitable matrix for PDLF.

The HA-TCP macroporous disk may elicit significant new bone formation due to its rigid space-maintaining scaffold and pore size for vascular ingrowth. It is well tolerated by host tissues and may be a suitable carrier for growth factors.

Our results suggest that nicotine may induce an altered compartmentalization process in which beta1 integrin molecules are produced, but are not appropriately transferred to the membrane. Nicotine effects on cellular protein synthesis and its modulation of beta1 integrin expression may impair gingival fibroblast ability to adhere to and communicate with one another and with the extracellular matrix, which could impair wound healing and/or exacerbate periodontal disease.
