Effect of Septal Deviation, Concha Bullosa and Haller's Cell on Maxillary Sinus's Inferior Pneumatization; a Retrospective Study.

Maxillary sinus's inferior pneumatization is a physiological process, which increase with time and accelerates following extraction. The aim of this study was to determine the prevalence of nasal septal deviation (NSD), concha bullosa (CB), and Haller's cells (HC) and to examine the correlation of maxillary sinus inferior pneumatization (MSIP) with these anatomical variations. Material and Methods : 300 (150 m, 150 f) CBCT scans taken at the Marmara University School of Dentistry from 2011 to 2014 were retrospectively reviewed for the presence of CB, NSD, HC and MSIP.

Cytokine profiles in serum of patients with oral lichen planus.

Objective: Oral lichen planus (OLP) is a chronic inflammatory disorder of oral mucosa, which represents T-cell-mediated autoimmune diseases. The inflammatory response in OLP is characterized by the accumulation and expansion of T-helper 1 (Th1) lymphocytes. Several lines of evidence have suggested that a complex cytokine network plays an important role in the exacerbation and perpetuation of OLP.

Evaluation of cytotoxic T-cell activation, chemokine receptors, and adhesion molecules in blood and serum in patients with oral lichen planus.

Background: Our purpose is to study cytotoxic T-cell activation (through evaluation of CD8+CD40+ and CD8+CD154+ cells), chemokine receptors (through evaluation of CD8+CD184+ and CD8+CD195+ cells), and adhesion molecules (through evaluation of CD8+CD152+ cells) which play a part in cell activation in blood and serum samples of patients with OLP and then to compare them with healthy controls.

Methods: Thirty patients with OLP, and 30 matched healthy controls participated. The mean ages of OLP patients and controls were 51,10 ± 12,25 and 48,09 ± 11,92, respectively.

Interleukin-2, interleukin-6 and T regulatory cells in peripheral blood of patients with Behçet's disease and recurrent aphthous ulcerations.

Background: One of the factors involved in the pathogenesis of Behçet disease (BD) and recurrent aphthous ulcerations (RAU) is a cell-mediated immune response in which several cytokines (interleukin-2, interleukin-6) and T regulatory cell (T reg cell) population seem to play a major role. The aim of this study was to measured the interleukin-2 (IL-2), interleukin-6 (IL-6) levels and analysis of CD4(+) CD25(+) Foxp-3(+) Treg cells in peripheral blood from patients with BD and RAU. In addition; we also analysed peripheral blood from healthy subjects for comparison.

Evaluation of demands and needs for dental care in a sample of the Turkish population.

Objectives: To evaluate the demands and needs for dental care and to identify the level of dental and periodontal status in patients of different age groups visiting the Faculty of Dentistry, Marmara University, Istanbul, Turkey.

Methods: A total of 1000 first-visit patients (517 female and 483 male) were examined and questioned. The main complaint of each patient was recorded and considered to be a measure of demand for dental care.
