Abstract:
Ghrelin plays a major role in obesity-related diseases which have been shown to be associated with periodontitis. This study sought to analyze the expression of the functional receptor for ghrelin (GHS-R1a) in periodontal cells and tissues under microbial conditions in vitro and in vivo. The GHS-R1a expression in human periodontal cells challenged with the periodontopathogen Fusobacterium nucleatum, in gingival biopsies from periodontally healthy and diseased individuals, and from rats with and without ligature-induced periodontitis was analyzed by real-time PCR, immunocytochemistry, and immun

Abstract:
<p>Periodontal disease is a chronic inflammatory disease that is largely attributable to infections with gram-negative bacteria and is characterised by both gingival inflammation and alveolar bone resorption. Beside macrophages, the second most common cells of the gingival inflammatory infiltrat are mast cells. Mast cells are heterogenous cell population which live from six months to one year. These cells are activated by differnt immunologic and non-immunologic signals. Activated mast cells can secrete a range of substances that regulate angiogenesis, tissue remodeling and wound

Introduction: Periodontal disease (PD) is the most common bone destructive chronic inflammatory disease in humans. Severe PD affects 8-15% of the population and impacts on the ability to chew and appearance, reduces quality of life, and is responsible for a substantial proportion of dental care costs. A dysbiotic oral biofilm is necessary but insufficient for development of PD. Rather, a dysregulated immune response to the disease-associated biofilm results in destruction of tooth supporting structures and eventual tooth loss. Despite the apparent involvement of the immune system in PD, clinic

The cell surface proteins signal regulatory protein alpha (SIRPα) and cluster of differentiation 47 (CD47) are important for the progression of the inflammation in rheumatoid arthritis and Crohn's disease.

Periodontitis is a chronic inflammatory disease initiated by gram negative anaerobic bacteria. These bacteria possess pathogen-associated molecular patterns (PAMPs) that interact with various receptors including Toll like receptors (TLRs). Bacterial DNA (bDNA) is one of the PAMPs mainly recognized by TLR9. Interaction of bDNA and its receptors leads to activation of inflammatory signaling pathways potentially resulting in periodontal bone destruction. The aim of this study was to determine the production of IL- 6 and IL-8 in response to periodontal bDNA from human osteoblastic cells (MG-

Abstract:
Background and objectives: The most widely accepted tooth movement model is defined by the pressure-tension hypothesis. An orthodontic force applied to a tooth generates areas of compression and tension in the periodontal ligament (PDL), which are transmitted to the alveolar bone. Areas of tissue exposed to tensile strain undergo bone deposition, whereas areas of tissue exposed to compressive strain undergo bone resorption. We propose that human PDL cells in monolayer culture exposed to tensile mechanical strain would express multiple genes involved in osteogenesis. Materials and Methods: Hu

Diabetes in relation to dentistry is the topic of this chapter. The incidence of diabetes is increasingly rapidly, hand-in-hand with the increase in obesity. Obesity predisposes patients to an increased insulin resistance, i.e. reduces their ability to increase the glucose transport into adipocytes, muscle, and liver cells. The pancreas responds by producing more insulin but when it can no longer produce enough to overcome the insulin resistance, the blood glucose rises. Diabetes is characterized by raised blood glucose. We describe the devastating long-term effects of diabetes, in particular

Background: Mechanical stress such as orthodontic forces can produce mechanical damage and inflammatory reaction in periodontium.

Abstract:
Background: The LPS of A.actinomycetemcomitans is one of the major pathogenic factors in periodontal disease. It induces secretion of pro-inflammatory cytokines and involves in alveolar bone destruction. We hypothesized that the LPS of A.actinomycetemcomitans could affect the activation of MMP-2 and the expression of RANKL and OPG in HPDL cells leading to the destruction of periodontium. Methods: HPDL cells were cultured in serum-free medium with or without the LPS of A.actinomycetemcomitans for 36 hours. The activation of MMP-2 was analyzed by zymography. Changes of the expression of RANKL an

Abstract:
Extract from mangosteen pericarp has demonstrated various pharmacological activities including anti-bacterial, anti-inflammatory and anti-fungal. It may have potential for the treatment of periodontal disease, which is a chronic inflammatory disease caused by anaerobic bacteria. The aim of this study was 1) to investigate the toxicity of mangosteen extract to human gingival fibroblast, 2) to examine the anti-bacterial activity of the extract against periodontopathic bacteria including P. gingivalis and A. actinomycetemcomitans, and 3) to examine the inhibitory effect of the extract on PGE[subs

Abstract:
Background and objectives: IL-17 is a novel T cell-derived cytokine that promotes inflammatory responses. It is presence in inflamed gingival tissues and gingival crevicular fluid of periodontitis patients. In this study we investigated the effects of IL-17 alone or in combination with IFN-Y on the immune modulation of human gingival fibroblasts (HGFs) which would contribute to pathogenesis of periodontium. Methods and results: Various concentrations of IL-17, IFN-Y or the combination of these two cytokines were added to HGF cultures. The expression of ICAM-1, HLA-DR, and CD40 was assessed by
