    (Aves Press Ltd, 2018) Bilgic, Fundagul; Kucuk, Eyup Burak; Sozer, Ozlem Akinci; Ay, Yazgi; Kaya, Abdullah; Kaptac, Murat
    Objective: To analyze the article type, origin, main affiliation, number of publications, authors, and affiliations of six orthodontic journals during two intervals of 5 years each (2006-2010 and 2011-2015). Methods: In total, 4879 articles examined in this study were screened online at the individual journal's website. The types of articles and their authorship characteristics in the six orthodontic journals [three journals indexed by Science Citation Index (SCI) and the others indexed by Science Citation Index Expanded (SCIE)] were recorded. Parameters were tested using the Pearson chi-square for independence at a 0.05 level of significance. Results: Among all the article types, research articles were the most published in the orthodontic journals indexed by SCI and SCIE in the first (2006-2010; 88.1% and 77.6%, respectively) and second periods (2011-2015; 84.4% and 74.6%, respectively). In the first and second intervals, the European Union was the most common origin among articles accepted by the journals listed in SCI (30.1% and 29.2% respectively), whereas Asia/Oceania was the common origin among articles accepted by the journals listed in SCIE (44.1% and 43.4%, respectively). Conclusion: The articles published in the orthodontics journals listed under SCI and SCIE for 2006-2010 and 2011-2015 were significantly different in terms of numbers and characteristics.

    Evaluation of inflammation during fixed orthodontic treatment
    (Pergamon-Elsevier Science Ltd, 2016) Bilgic, Fundagul; Sozer, Ozlem Akinci; Ozcan, Oguzhan; Gurpinar, Ahmet Burak; Yilmaz, Hakki; Ay, Yazgi
    Objective: The aim of this study was to assess effects of fixed orthodontic therapy on high-sensitivity C-reactive protein (hs-CRP) level, CBC parameters and levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), urea, creatinine, sodium (Na), potassium (K), calcium (Ca), total protein (TP), and albumin (Alb). Design: Blood samples (7 ml) were drawn at baseline, on days 1 and 7, and three months after placement of braces in the study group, while only one blood sample was drawn at baseline in the control group. Serum hs-CRP levels were measured by nephelometric method. Friedman two-way variance analysis was used to assess values with skewed distribution obtained at baseline, on days 1 and 7, in the third month. Wilcoxon rank sign test was performed if median values were unequal. Results: During measurement periods, there were significant increases in hs-CRP level, WBC count and neutrophil count while a significant decrease in Na level (p < 0.05). K level was significantly decreased on the day 1. No significant differences were detected in other biochemical parameters evaluated. Conclusion: Elevation in serum hs-CRP levels and neutrophil: lymphocyte ratio within first 3 months indicates that a systemic immune response develops against therapy in patients undergoing fixed orthodontic therapy.
