A smile is a mesmerizing expression of joy, success, courtesy and reveals self-confidence. The harmony of the smile is determined not only by the shape, position and the color of teeth, but also by the gingival architecture. Gingival tissues form an important part of what we can consider to be a pleasing smile. The elegance of this pleasant smile could be, affected by highly pigmented gingiva. This gingival pigmentation occurs as a result of melanin granules, which are produced by melanoblast. Although melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly sort by people with moderately pigmented gingiva...

Background and objective:FAM20A gene mutations result in enamel renal syndrome (ERS) associated with amelogenesis imperfecta (AI), nephrocalcinosis, gingival fibromatosis, and impaired tooth eruption. FAM20A would control the phosphorylation of enamel peptides and thus enamel mineralization. Here, we characterized the structure and chemical composition of unerupted tooth enamel from ERS patients and healthy subjects. Methods: Tooth sections were analyzed by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X-Ray Diffraction (XRD), and X-Ray Fluorescence (XRF)...

BACKGROUND: Zirconia abutments are frequently used for implant-supported single crowns. Even though demonstrating esthetic benefits compared to metal abutments, zirconia abutments lead to an increased brightness of the peri-implant mucosa compared to natural teeth and are not ideal from an esthetic point of view. PURPOSE: To test whether or not a fluorescent hybrid zirconia abutment offers superior esthetics compared to a non-fluorescent one-piece zirconia abutment based on spectrophotometric analysis...

BACKGROUND AND OVERVIEW: "Pink esthetics," which are considered to be as important as "white esthetics," have attracted increasing attention. To date, clinicians rarely have applied computer-aided design and computer-aided manufacturing (CAD/CAM) techniques in the rebuilding of the contour of the marginal gingiva in the esthetic zone. CASE DESCRIPTION: In this case report, the authors describe a female patient who had gingival inflammation and an asymmetrical contour of the marginal gingiva of the anterior maxillary teeth because previously placed ceramic crowns violated the biological width...

Gingiva is a unique tissue which protects the underlying periodontal tissues from consistent mechanical and bacterial aggressions. Molecular analysis of gingiva is likely to improve our understanding of the underlying biological processes at work. The aim of this preliminary exploratory study is to analyze the proteomic profile of healthy gingiva and to detect prominently expressed proteins. Gingival tissue samples were obtained from periodontally healthy individuals who underwent surgical crown lengthening procedure...

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)...
