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)...

This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration...

Esthetic implant therapy can be challenging in the anterior maxilla, and meticulous treatment is often required to deliver optimal esthetics. Close collaboration between surgical and prosthetic team members using the novel approach of prosthetic crown lengthening helped camouflage a shallow implant platform location, providing the proper gingival frame for esthetic restorations. This case report presents an interdisciplinary approach that included ridge augmentation, second-stage crown lengthening, and prosthetic soft tissue manipulation to address an implant placed too shallow in the alveolus of an extraction socket...

Crown lengthening by forced eruption is usually followed by conventional surgical procedures. The aim of the present study was to evaluate clinical use of Nd:YAG laser fiberotomy in crown lengthening by forced eruption as an alternative to surgery. Patients who needed crown lengthening were enrolled in this prospective case series and underwent forced eruption. Fiberotomy by Nd:YAG laser was performed 2 days after initiation of forced eruption and every 2 weeks afterward to reach optimum clinical crown length...

Background The size, proportion and gingival zenith position of maxillary anterior teeth plays in the anterior teeth esthetics. Objective To compare the gingival zenith positions and levels between male and female in right and left side as an esthetic parameter. Method Impression of the maxillary arch was made in each participant with irreversible hydrocolloid, and dental cast was made with dental stone type IV. Two clinical parameters were evaluated: (1) the gingival zenith position (GZP) from the vertical bisected midline along the long axis of each individual maxillary anterior tooth; and (2) the gingival zenith level (GZL) of the lateral incisors in an apical-coronal direction relative to the gingival line joining the tangents of the GZP of the adjacent central incisor and canine teeth under healthy conditions...

Lip repositioning surgery to address excessive gingival display induced by different etiologies has received major attention recently. Several techniques and variations have been reported, including myotomy or repositioning of the levator labii superioris muscle, Le Fort impaction, maxillary gingivectomies, botulinum toxin injections, and lip stabilization. This study reports a case of excessive gingival display treated by a modified combined approach. A 25-year-old woman with a 4- to 8-mm gingival display when smiling caused by a combination of short clinical crowns induced by an altered passive eruption and hypermobility of the upper lip underwent a staged esthetic crown-lengthening procedure followed by a modified lip repositioning technique...

INTRODUCTION: Conventional methods to estimate the time of death are adequate, but a histological method is yet unavailable to assess postmortem interval (PMI). The autolytic changes that occur in an unfixed antemortem gingival tissue which reflects histologically at an early stage are similar to changes that occur in postmortem tissue. These histological changes can be used and applied in a postmortem tissue as a method to assess PMI. AIMS: The aim of the study is to assess the histological changes in a gingival tissue left unfixed for various time intervals and to correlate the findings with duration...
