BACKGROUND AND OBJECTIVE Cytokines produced by various cells are strong local mediators of inflammation. Mucosa-associated epithelial chemokine (CCL28), interleukin-8 (IL-8), interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) are major cytokines that play important roles in the periodontal inflammatory process. In this study we aimed to(More)
OBJECTIVE Oral lichen planus (OLP) is a chronic inflammatory disease of unknown aetiology. The aim of this study was to investigate matrix metalloproteinase (MMP)-1, MMP-9, and MMP inhibitor-1 (TIMP-1) levels in gingival crevicular fluid (GCF) by enzyme-linked immunosorbent assay and to investigate MMP-1, MMP-9, and TIMP-1 levels in gingival tissue by(More)
BACKGROUND AND OBJECTIVE Human β-defensins (hBDs) have a strong antibacterial action against various microorganisms, especially periodontal pathogens. The aim of this study was to compare the total levels of hBD-1 and hBD-3 in the gingival crevicular fluid of healthy patients with gingivitis (HG), healthy patients with chronic periodontitis (HP), patients(More)
BACKGROUND Beta-2 microglobulin (B2M) and alpha-2 macroglobulin (A2M) play key roles in the immune system. The aim of this study was to compare B2M and A2M levels in patients with different periodontal diseases. METHODS Eighty patients (20 periodontally healthy, 20 with gingivitis, 20 with chronic periodontitis and 20 with generalized aggressive(More)
BACKGROUND AND OBJECTIVE To achieve satisfactory osseointegration, primary stability and healthy peri-implant tissue must be available. In this study, our objective was to compare the adrenomedullin, human beta-defensin (hBD)-1 and hBD-2 levels in implants with different implant stability quotient (ISQ) values and with different peri-implant tissue health(More)
OBJECTIVES The aim of this study is to determine the relationship between atherosclerosis and periodontopathogenic microorganisms in chronic periodontitis patients following periodontal treatment. MATERIALS AND METHODS A total of 40 patients were included in the study. 20 of these patients diagnosed with atherosclerosis and chronic periodontitis formed(More)
BACKGROUND AND OBJECTIVE Adrenomedullin, an antimicrobial peptide, has biological applications in many tissues, but its main attribute is its ability to lower arterial pressure. The plasma adrenomedullin level is elevated in pathophysiological conditions such as arterial hypertension, acute coronary syndrome, renal diseases, diabetes mellitus and(More)
The aim of this study was to determine the myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of smoker patients with generalized aggressive periodontitis (SAgP), smoker patients with chronic periodontitis (SCP), smoker patients with gingivitis (SG-smoker control), non-smoker patients with generalized aggressive(More)
BACKGROUND AND AIMS The aim of this study is to compare patients with atherosclerosis and chronic periodontitis and patients who are systemically healthy and chronic periodontitis using alteration of adrenomedullin (ADM), chemokine (C-C motif) ligand 28 (CCL-28), white blood cell levels, platelet levels, high-density lipoprotein, low-density lipoprotein,(More)
BACKGROUND AND OBJECTIVE Cathelicidin (LL-37) and human β-defensin-2 (hBD-2) are antimicrobial peptides that have additional functions in innate immunity. The purpose of this study was to evaluate LL-37 and hBD-2 levels in the following patient groups: non-smoker patients with gingivitis (G), smoker patients with gingivitis (SG), non-smoker patients with(More)
