Treatments of horizontal root fractures: four case reports

EBRU KÜÇÜKYILMAZ

Horizontal root fractures are rare in comparison to other types of injuries and the reported prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root fractures depend on many variables, the most important being the length of time between trauma and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing. The aim of these case reports is to present four different patients who had horizontal root fractures of imma ...Daha fazlası

Surgical Treatment Of Symptomatic Coiling Or Kinking Internal Carotid Artery

GALİP AKHAN | ALİ GÜRBÜZ | LEVENT YILIK

Coiling of the artery is a rare morphologic entity most frequently described in the internal carotid artery. Herein we present two cases with symptomatic kinked internal carotid artery: one suffering from paresthesia of the right arm and speech disturbances and the other suffering from weakness of the left half of the body and speech disturbances. Both patients were treated surgically. None of the patients experienced any peri- or postoperative complications.

Yeni Araştırmalar Bağlamında Diyarbakır Kalesi

RAZAN AYKAÇ

Diyarbakır farklı din, kültür ve devletlerin hâkimiyeti altında kalmış ve tarihin her döneminde medeniyetlerin ilgi alanı olmaya devam etmiştir. Hıristiyanlık ve İslam bu şehirde hüküm süren iki önemli dindir. Romalılar, Partlar, Sasaniler ve Bizans İslam öncesi dönemin bölgeye hâkim olan devletleri olarak öne çıkmaktadır. Diyarbakır’da İslam fethi Hz. Ömer devrinde gerçekleşir. Hulefâ-i Râşidîn döneminden sonra yönetimi Emeviler devralmış bu dönemde Diyarbakır onların hâkimiyeti altında kalmıştır. Abbasiler dönemi Diyarbakır’da kitabelerine en çok rastlanan dönemlerden biri olarak görülmekted ...Daha fazlası

Comparison of craniofacial morphology, head posture and hyoid bone position with different breathing patterns

TANCAN UYSAL

Objectives: The aim of this study was to evaluate differences in craniofacial morphology, head posture and hyoid bone position between mouth breathing (MB) and nasal breathing (NB) patients. Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of 12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements (15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements were evalu ...Daha fazlası

Measurements from conventional, digital and CT-derived cephalograms: a comparative study

ASLI BAYSAL

Objective: The purpose of this retrospective radiographic study was to determine the reliability and reproducibility of skeletal and dental measurements of lateral cephalograms created from a computerised tomography (CT) scan compared with conventional and digital lateral cephalograms. Methods: CT and conventional lateral cephalograms of the same patients were obtained from university archives. The lateral cephalometric radiographs of 30 patients were manually traced. The radiographs were subsequently scanned and traced using Dolphin Imaging software version 11 (Dolphin Imaging, Chatswort ...Daha fazlası

Turkish Character Usage in Text Classification

Ali Aycan KOLUKISA

Abstract This study is prepared to examine the effects of Turkish character usage on text data by using multiple classifiers. Regression Classifiers, SVM, NB-Classifiers, and ANN are frequently used in supervised learning methods, especially in classification problems. Regression classifiers generally come in two types: as Linear and Logistic. There are also more than one type of Naive Bayes classifier. In our study, after mentioning the properties of Linear Regression and Logistic Regression classifiers in general terms, why Logistic Regression is much more suitable for this study is explaine ...Daha fazlası

Mandibular anterior bony support and incisor crowding: Is there a relationship?

İLKNUR VELİ

INTRODUCTION: The aim of this study was to test the null hypothesis that increased irregularity of the mandibular incisors is associated with a reduction in the alveolar support on cone-beam computed tomographic sections. METHODS: From a sample of 1100 digital volumetric tomographs, 125 tomographs of subjects with Class I malocclusion (mean age, 21.6 ± 4.8 years) were selected for this study. An irregularity index was used to categorize these tomographs as having mild, moderate, or severe crowding. All tomographs were taken by using an iCAT (Imaging Sciences International, Hatfield, Pa) ima ...Daha fazlası

Henry Corbin, Tanrının Yüzü İnsanın Yüzü: Yorumbilgisi ve Tasavvuf, çev. Kübra Gürkan, B. Garen Beşiktaşlıyan

Hermeneutik ve tasavvuf arasındaki ilişki özellikle son dönemde tasavvuf metinlerinin muhtevasını anlama girişimleriyle artmış ve belirginleşmiştir. Birçok çalışmada doğaüstü olarak kabul edilen bu mistik metinlerin yapısı, içinde bulunduğu geleneğin de etkisiyle kapalı kalmış ve ulaşılamadıkça okur için daha da büyük bir ilgi odağı haline gelmiştir. Hermeneutik bir tavırla tasavvuf metinlerine nüfuz edilebileceği düşüncesi ise halen tartışmalıdır.

Modeling and Design Optimization to Determine the Mechanical Properties of a Recent Composite

Naciye Burcu KARTAL

This study proposes an appropriate optimization model for determining a new composite material's mechanical properties by neuro-regression analysis. This new composite material is obtained by combining hemp and polypropylene fibers. It was developed for the sector of upholstered furniture. First, different multiple regression models have been tried for input and output values. The R2 training, R2 testing, R2 validation, and minimum, maximum values were determined for each model. Then, the stochastic optimization approach is used to predict and optimize the mechanical properties of the new bioc ...Daha fazlası

Effect of LED-mediatedphotobiomodulation therapy on orthodontic tooth movement and root resorption in rats

TANCAN UYSAL

The aim of this experimental study was to evaluate the effects of light-emitting diode-mediated-photobiomodulation therapy (LPT), on the rate of orthodontic tooth movement (TM) and orthodontically induced root resorption, in rats. Twentymale 12-week-oldWistar rats were separated into two groups (control and LPT) and 50 cN of force was applied between maxillary left molar and incisor with a coil spring. In the treatment group, LPT was applied with an energy density of 20 mW/cm2 over a period of 10 consecutive days directly over the movement of the first molar teeth area. The distance b ...Daha fazlası
