BACKGROUND AND OBJECTIVE Mechanical stress by an orthodontic appliance induces biologically active substances. Fibroblast growth factor is a multifunctional cytokine that has various effects on fibroblast cells, and fibroblast growth factor-2 plays an important role in remodeling of the periodontal ligament. The receptor activator of nuclear factor kappa B(More)
OBJECTIVE To determine the levels of the receptor activator of NFkB ligand (RANKL) and osteoprotegerin (OPG) in the gingival crevicular fluid (GCF) during orthodontic tooth movement. A second objective was to investigate the effect of compression force on RANKL and OPG production from human periodontal ligament (hPDL) cells. DESIGN Ten adolescent patients(More)
OBJECTIVE The aim of this study was to investigate how interleukin (IL)-8 (cytokine-induced neutrophil chemoattractant; CINC-1) and monocyte chemotactic protein (MCP)-1/CCL2 contribute to root resorption during orthodontic tooth movement. MATERIALS AND METHODS Forty 6-week-old male Wistar rats were subjected to orthodontic force of 10 or 50 g to induce a(More)
OBJECTIVE The aim of this study was to investigate how T-helper 17 cells (Th17 cells), interleukin (IL)-17, and interleukin-6 contribute to root resorption during orthodontic tooth movement. MATERIALS AND METHODS Fifteen male 6-week-old Wistar rats were subjected to orthodontic force of 10 or 50 g to induce a mesially tipping movement of the upper first(More)
OBJECTIVES Relapse of teeth that have moved during orthodontic treatment is a major clinical issue with respect to the goals of successful treatment. Such relapse is a physiologic response of the supporting tissues to application of force, and is mainly attributed to occlusal instability and increased mechanical tension exerted by the periodontal ligament(More)
(Shaked etal., PLoS ONE 2008). To further investigate this finding, several different approaches have been taken. First, the expression of HDAC-regulated candidate genes responsible for controlling neurogenesis has been examined through quantitative real-time RT-PCR. TSA-based inhibition of HDAC activity resulted in upregulation of Bmp2, Stat1, Stat3, Ngn1(More)
