INTRODUCTION: Cyclosporin-A (CsA), an immunosuppressant, induces renal fibrosis and Renin Angiotensin System (RAS) is known to play a major role. CsA has the potential to increase the oxidative stress; specifically through the Advanced Oxidation Protein Products (AOPP) which could possibly stimulate fibrosis. A similar type of pathology occurs even in the gingiva known as CsA Induced Gingival Overgrowth (CIGO). AIM: This study was undertaken to estimate the AOPP generation by Human Gingival Fibroblasts (HGF) under the influence of CsA and Angiotensin II (Ang II)...

OBJECTIVE: Visfatin is an adipocytokine that plays a role in regulating periodontal inflammation by as yet identified mechanisms. It has been suggested that visfatin mediates inflammation via activation of the nuclear factor-kappa B (NF-κB) and phosphatidylinositol 3-kinase (PI3k) signaling pathways which play a role in the inhibition of neutrophil apoptosis. The aim of this study was to investigate the expression of visfatin, NF-κB (NF-κB1 and NF-κB2), PI3k, tumor necrosis factor alpha (TNF-α), and interleukin-1 beta (IL-1β) in the tissue of healthy individuals and patients with periodontitis...

Gingival recession has a diverse etiology. The consequences may include gingivitis, periodontitis, and hypersensitivity. Whereas the management can include surgical treatment options, sometimes a more conservative, yet still esthetic approach may be required. The use of gingiva-colored composites provides one such alternative and can be applied to varying presentations of the problem. While surgical treatment can be successful in re-creating favorable esthetic anatomy as well as achieving accurate tissue contour in cases when minor amounts of tissue are reconstructed, long-term results vary because of the vascularity and complexity of the interdental space...

OBJECTIVES: Gingival recession is the term used to characterize the apical shift of the marginal gingiva from its normal position on the crown of the tooth. It is frequently observed in adult subjects. The occurrence and severity of the gingival recession present considerable differences between populations. To prevent gingival recession from occurring, it is essential to detect the underlying etiology. The aim of the present study was to determine the occurrence of gingival recession and to identify the most common factor associated with the cause of gingival recession...

While, overall, dental implants are highly efficacious, consistently achieving predictable esthetic results can pose color-driven challenges at the implant/soft-tissue interface, particularly in the esthetic zone. An ongoing, 5-year, multicenter (eight sites) prospective study is following a total of 168 implants placed in 120 patients using a novel biomimetic (osteoconductive) implant system with pink collars and abutments that afford better gingival color matching, enhanced design variability, and streamlined fabrication and customization of the abutment/implant-tissue interface...
