Öğe Analysis of Six Orthodontic Journals in Science Citation Index and Science Citation Index Expanded: A Bibliometric Analysis(Aves Press Ltd, 2018) Bilgic, Fundagul; Kucuk, Eyup Burak; Sozer, Ozlem Akinci; Ay, Yazgi; Kaya, Abdullah; Kaptac, MuratObjective: 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.Öğe The applicability of Willems' method for age estimation in southern Turkish children: A preliminary study(Elsevier Sci Ltd, 2016) Altan, Halenur Onat; Altan, Ahmet; Bilgic, Fundagul; Sozer, Ozlem Akinci; Damlar, IbrahimThe aims of the present study were to evaluate the applicability and accuracy of Willems' method for assessing southern Turkish children and to analyze the practicability of this method in different age groups for both genders. Panoramic radiographs of 756 children (378 females, 378 males) aged between 5 and 14.99 years were examined by one observer. This retrospective study involved a contemporary southern Turkish population. The chronological ages of the subjects were divided into 10 groups. These 10 groups consisted of children of the following ages 5 and 14.99. Relationships between continuous variables were examined using Pearson's correlation coefficient. The paired t-test was used to compare all data according to gender and age groups. A p-value of less than 0.05 was considered significant for all statistical data. According to the results, a very high correlation was found for both girls (r(2) = 0.946) and for boys (r(2) = 0.940). Dental age (DA) and chronological age (CA) were consistent for girls in the four age groups (5-5.99, 6-6.99, 12-12.99, and 14-14.99) and for boys in the three age groups (5-5.99,13-13.99, 14-14.99). The maturity score of Willems' Belgian samples of the DA was applicable to seven groups of the southern Turkish children. The present study reports that Willems' method is more accurate for girls than for boys. (C) 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Human-extracted premolars were randomized to three groups (n = 17) depending on the conditioning treatment used for the buccal surfaces: 37 % orthophosphoric acid, Er:YAG laser etching (MSP mode 120 mJ, 10 Hz, 1.2 W), and femtosecond laser etching (0.4 W, 800 nm, 90 fs/pulse, 1 kHz). Metal brackets were bonded with Transbond XT to the conditioned surfaces and light cured for 20 s. The samples were thermocycled (5000 cycles, 5-55 A degrees C) and subjected to shear bond strength (SBS) testing using a universal testing machine. Failure types were analyzed under an optical stereomicroscope and SEM. The adhesive remnant index (ARI) was evaluated to assess residual adhesive on the enamel surface. The results revealed no significant differences in SBS between the Er:YAG laser (7.2 +/- 3.3 MPa) and acid etching groups (7.3 +/- 2.7 MPa; p < 0.05), whereas a significant difference was observed between the femtosecond laser etching group (3.3 +/- 1.2 MPa) and the other two groups (p < 0.01). ARI scores were significantly different among the three groups. The results of our study suggest that laser conditioning with an Er:YAG system results in successful etching, similar to that obtained with acid. The sole use of a femtosecond laser system may not provide an adequate bond strength at the bracket-enamel interface.Öğe Dental Age Estimation in Southern Turkish Children: Comparison of Demirjian and Willems Methods(Kowsar Corp, 2017) Altan, Halenur; Altan, Ahmet; Sozer, Ozlem AkinciBackground: Age-related legal problems are particularly common in underdeveloped parts of Turkey. Age determination is important in terms of both laws and penalties in the legal process. Objectives: The aim of the present study was to compare the validity of the Demirjian and Willems methods in southern Turkish children. Methods: In this retrospective study, panoramic radiographs of 745 southern Turkish children (382 boys and 363 girls) aged between 4 and 15.99 years were examined by one investigator. According to Demirjian and Willems method, the mean difference between chronological and dental age was calculated for each sex and age group. The Wilcoxon test was used to compare all data. Statistical analysis was performed to test the validity of Demirjian and Willems methods by comparing the mean estimated and chronological age. Results: The Demirjian's method overestimated age with a mean accuracy of 0.832 in females and by 0.923 in males, while Willems method overestimated it by 0.202 in females and 0.434 in males. Conclusions: The dental age estimation by Willems method was found to be more accurate than Demirjian method in contemporary Turkish pediatric population.Öğe 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, YazgiObjective: 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.

Materials and Methods: Totally 54 male and female subjects, including 27 using bonded rapid maxillary expander and 27 patients without orthodontic treatment, were entered in the present study. The study group consisted of 27 patients (14 females and 13 males) suffering from both maxillary constriction and posterior cross-bite. Patients treated with a rigid acrylic, bonded rapid maxillary expander were evaluated two times using oral rinses: one at baseline (T0) and 2 after palatal spreading out (T1). The data were analyzed using a chi-square test and a Fisher's exact test. Results: After the use of RME, no significant changes were found between the data showing C. albicans colonies at T0 and at T1 (p=1.964). Conclusion: Our data suggest that the RME therapy and appliance did not cause a significant change in oral C. albicans colonization.Öğe Relationship between voice function and skeletal effects of rapid maxillary expansion(E H Angle Education Research Foundation, Inc, 2018) Bilgic, Fundagul; Damlar, Ibrahim; Surmelioglu, Ozgur; Sozer, Ozlem Akinci; Tatli, UfukObjective: To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite. Materials and Methods: Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 +/- 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearson's correlation. Results: RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 (P < .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 (P < .001 and P = .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases (P = .037 and P = .019, respectively). Conclusions: After RME therapy, voice quality differences were found to be associated with increases in nasal width.Öğe Residual monomer release from orthodontic adhesives cured with different light sources(Taylor & Francis Ltd, 2016) Botsali, Murat Selim; Sozer, Ozlem Akinci; Altunsoy, Mustafa; Demir, Abdullah; Ulker, Hayriye EsraIntroduction: The aim of this study was to evaluate the residual monomer release from orthodontic adhesives cured with light-emitting diode (LED) and halogen light sources.Methods: Seven hundred and twenty stainless steel brackets were divided into 3 groups according to the adhesive system used (Transbond XT light-cure adhesive [TXT], Transbond LR capsule [LR], and Light Bond light-cure adhesive paste [LB]), and each group was divided into 2 subgroups according to light-curing procedure (LED or halogen). Brackets were bonded with adhesives onto tooth buccal surfaces and polymerized. Each specimen contained 24 brackets that simulated the oral environment (n=5). The specimens were immersed in a 75% ethanol/water solution at 37 degrees C for 10min, 1h, 1 d, 7 d, 14 d, and 30 d, respectively. Eluted monomers (Bis-GMA, UDMA, and TEGDMA) were detected using HPLC.Results: There was residual monomer release at all time periods, and the highest amount of release was observed cumulatively on the 30th day. The cumulative Bis-GMA released from adhesives was not different (p>0.05). The cumulative TEGDMA released from adhesives was statistically different (p<0.05). There was no statistical difference between QTH and LED light-curing units for each adhesive (p>0.05).Conclusions: The release of residual monomers stays at a high level for a long time after polymerization. The total leaching of residual monomers from the Light Bond light-cure sealant resin plus Light Bond light-cure adhesive paste was higher than that of other materials for both curing units. Different curing units (LED or QTH) did not affect the monomer release from the orthodontic adhesives.Öğe *The role of overflow filling to occur orthodontic bad habit: A rare case report(University of Dicle, 2016) Bilgic, Fundagul; Arslanoglu, Zeki; Altan, Halenur; Yilmaz, Hakki; Sozer, Ozlem AkinciMalocclusions occurring in children can originate from a genetic origin or from s acquired after birth. "Force" implementation happens due to long-term. This force can be exerted by the tongue, cheek, finger or foreign bodies. In this case report, it was presented the orthodontic treatment of positioning to the vestibule in the arch was caused by applying tongue force to the tooth which overflowed filling.
