A rare case of gingival necrosis following an extraoral injection of dermal filler.

Background: The utilization of dermal fillers for cosmetic procedures has increased dramatically in the past several years, and so is the number of reported adverse events and complications. Most of these reports are centered on extraoral facial structures such as skin, nose, forehead, and eyes. However, as this report illustrates, intraoral complications are also possible and require appropriate management.

Use of Collagen Matrix Scaffolds as a Substitute for Soft Tissue Augmentation: Case Series.

Introduction: The presence of keratinized mucosa (KM) around natural teeth is believed to be beneficial in certain restorative, prosthetic, and orthodontic situations. Lack of adequate KM is common and predictably treated by autogenous gingival grafts (AGGs); however, AGGs have the disadvantages of harvest site morbidity, limited donor site availability, and compromised esthetics.

Case Presentation: This case series presents the use of the xenogeneic porcine bilayer collagen matrix (BCM) in increasing the width of attached KM around natural teeth.

Management of heat-induced bone necrosis following thermal removal of gutta-percha.

Many endodontically treated teeth require a post to improve the retention of the coronal restoration, which necessitates removal of the coronal part of the gutta-percha from the canal by thermal method, among other techniques. However, this technique carries the risk of heat conduction to the attachment unit of the periodontium and infliction of permanent damage especially in cases where the remaining root's dentin walls are thin. The overall objective of this article is to report on the clinical manifestations, histologic description, and periodontal management of three cases of heat-induced damage following thermal removal of gutta-percha.

The Potential Role of Curcumin in Periodontal Therapy: A Review of the Literature.

Periodontitis is a chronic inflammatory disease in the oral cavity caused by bacterial biofilm attached to tooth surfaces. The periodontal pathogenic microorganisms trigger the disease process; however, the destruction of the periodontium is mostly caused by the host's immune response to the bacterial insults. The main thrust of periodontal therapy has been centered traditionally on reducing the microbial load by mechanical and antimicrobial means.

Effect of 1,25(OH) D and 20(OH)D on interleukin-1β-stimulated interleukin-6 and -8 production by human gingival fibroblasts.

Background And Objective: Vitamin D-1,25(OH) D or 1,25D3-maintains healthy osseous tissue, stimulates the production of the antimicrobial peptide cathelicidin and has anti-inflammatory effects, but it can cause hypercalcemia. Evidence links diminished serum levels of 1,25D3 with increased gingival inflammation. Periodontitis progression is associated with increased local production of inflammatory mediators by immune cells and gingival fibroblasts.
